Section 3 Mounting The IM483 This section has recommended mounting instructions for the standard IM483. Special mounting instructions for any of the connection options for the IM483 are available in Appendix A: Standard Connection Options, of this document. An optional heat sink and thermal pad, the H-4X and TN-48, are available for the IM483. See Appendix C: Cooling Solutions, for details.
Section 4 Theory of Operation Section Overview This section will cover the circuit operation for the IM483 microstepping driver. Circuit Operation. Microstep Select Inputs. Stepping. Dual PWM Circuit. Fullstep Output. Timing. Circuit Operation Microstepping drives have a much higher degree of suitability for applications that require smooth operation and accurate positioning at low speeds than do half/fullstep drivers and reduction gearing.
PWM circuit uses alternating recirculating/non-recirculating modes to accurately regulate the current in the windings of a two phase stepping motor. Microstep Select (MSEL) Inputs Another unique feature of the IM2000 is the ability to change resolutions at any time. A resolution change can occur whether the motor is being clocked or is at rest. The change will not take place until the rising edge of the next step clock input.
The IM2000 outputs both sine and cosine data simultaneously when applying a step clock input. Dual internal look-up tables are used to output a unique position for every step clock input to enhance system performance. Dual PWM Circuit The IM2000 contains a unique dual PWM circuit that efficiently and accurately regulates the current in the windings of a two phase stepping motor. The internal PWM accomplishes this by using an alternating recirculating/non-recirculating mode to control the current.
with low inductance motors. On the downward cycle of the sine/cosine waveform, the PWM operates in a two part cycle. In the first part of its cycle, the PWM is in a non-recirculating mode to pull current from the motor windings. In the second part of the cycle the PWM reverts back to recirculating mode to increase efficiency and reduce current ripple.
Section 5 Power Supply Requirements Section Overview This section covers the power supply requirements of the IM483. Precise wiring and connection details are to be found in Section 7: Interfacing and Controlling the IM483. The following is covered by this section: Selecting a Power Supply. Recommended Wiring. AC Line Filtering. Selecting a Power Supply Selecting a Motor Supply (+V) Proper selection of a power supply to be used in a motion system is as important as selecting the drive itself.
out of each phase reservoir. This results in a less than expected current draw on the power supply. Stepping motor drivers are designed with the intent that a user’s power supply output will ramp up to greater than or equal to the minimum operating voltage of the drive. The initial current surge is substantial and could damage the driver if the supply is undersized. The output of an undersized power supply could fall below the operating range of the driver upon a current surge.
Recommended IMS Power Supplies IMS has designed a series of low cost miniature unregulated switchers and unregulated linears which can handle extreme varying load conditions. This makes them ideal for stepper motor drives and DC servo motors as well. Each of these is available in either 120 or 240 VAC configuration. See the IMS Catalog or web site (http://www.imshome.com) for information on these supplies. Listed below are the power supplies recommended for use with the IM483.
Recommended Wiring Rules of Wiring and Shielding Noise is always present in a system that involves both high power and small signal circuitry. Regardless of the power configuration used for your system, there are some wiring and shielding rules that should be followed to keep the noise-to-signal ratio as small as possible. Rules of Wiring Power supply and motor wiring should be shielded twisted pairs run separately from signal carrying wires. A minimum of 1 twist per inch is recommended.
ground leads to each driver from the power supply. The following twisted pair jacketed Belden cable (or equivalent) are recommended for use with the IM483. Belden Part# 9740 or equivalent 18 Gauge AC Line Filtering Since the output voltage of an unregulated power supply will vary with the AC input applied, it is recommended that an AC line filter be used to prevent damage to the IM483 due to a lightning strike or power surge.
Section 6 Motor Requirements Section Overview This section covers the motor configurations for the IM483. Selecting a Motor. Motor Wiring. Connecting the Motor.
Hybrid stepping motors combine the features of the PM stepping motors with the features of another type of stepping motor called a variable reluctance motor (VR). VR motors are low torque and load capacity motors which are typically used in instrumentation. The IM483 cannot be used with VR motors as they have no permanent magnet. On hybrid motors, the phases are wound on toothed segments of the stator assembly.

IMS Inside Out Stepper Motors The new inside out stepper (IOS) motor was designed by IMS to bring versatility to stepper motors using a unique multi-functional, hollow core design. This versatile new motor can be converted to a ball screw linear actuator by mounting a miniature ball screw to the front shaft face. Ball screw linear actuators offer long life, high efficiency, and can be field retrofitted. There is no need to throw the motor away due to wear of the nut or screw.
Motor Wiring As with the power supply wiring, motor wiring should be run separately from logic wiring to minimize noise coupled onto the logic signals. Motor cabling exceeding 1’ in length should be shielded twisted pairs to reduce the transmission of EMI (Electromagnetic Interference) which can lead to rough motor operation and poor system performance. For more information on wiring and shielding, please refer to Rules of Wiring and Shielding in Section 5 of this manual.
8 Lead Motors 8 lead motors offer a high degree of flexibility to the system designer in that they may be connected in series or parallel, thus satisfying a wide range of applications. Series Connection A series motor configuration would typically be used in applications where a higher torque at lower speeds is required. Because this configuration has the most inductance, the performance will start to degrade at higher speeds.
6 Lead Motors Like 8 lead stepping motors, 6 lead motors have two configurations available for high speed or high torque operation. The higher speed configuration, or half coil, is so described because it uses one half of the motor’s inductor windings. The higher torque configuration, or full coil, uses the full windings of the phases. Half Coil Configuration As previously stated, the half coil configuration uses 50% of the motor phase windings. This gives lower inductance, hence, lower torque output.
4 Lead Motors 4 lead motors are the least flexible but easiest to wire. Speed and torque will depend on winding inductance. In setting the driver output current, multiply the specified phase current by 1.4 to determine the peak output current. PHASE A PHASE A PHASE B PHASE B Figure 6.

Determining the Output Current Stepper motors can be configured as 4, 6 or 8 leads. Each configuration requires different currents. Shown below are the different lead configurations and the procedures to determine the peak per phase output current setting that would be used with different motor/lead configurations.
8 Lead Motors SERIES CONNECTION: When configuring the motor windings in series, use the per phase (or unipolar) current rating as the peak output current, or multiply the bipolar current rating by 1.4 to determine the peak output current. EXAMPLE: An 8 lead motor in series configuration with a specified unipolar current of 3.0A 3.0A per phase = 3.0 Amps Peak An 8 lead motor in series configuration with a specified bipolar current of 2.8A 2.8 x 1.4 = 3.
Setting the Output Current The IM483 uses an internal 1 milliamp current source to establish the reference voltage needed to control the output current. This voltage is programmed by means of an external 1/8 watt or higher, 1 percent resistor connected between P2:2 (Current Adjust) and P2:3 (Power Ground). The relationship between the output current and the current adjust resistor value is expressed as follows: Output Current = .
Reducing/Disabling the Output Current The IM483 has the capability of automatically reducing the current in the motor windings following a move. Use of this feature will reduce motor and driver heating, thus allowing for cooler operation and improved system power efficiency. The output current may be reduced to the level needed to maintain motor holding torque by means of a 1/8 watt or higher, 1 percent resistor. This resistor is connected between P2:1 (Reduction Adjust) and P2:2 (Current Adjust).
Controlling the Output Resolution The number of microsteps per step is selected by the DIP switch (SW1). Table 7.2 lists the standard resolution values along with the associated switch settings for a 1.8° stepping motor. If a motor with a different step angle is used, then the steps per revolution resolution will have to be calculated manually by multiplying the microsteps/ step setting by the number of full steps per motor revolution. For example, a 0.

Interfacing and Using the Isolated Logic Inputs The IM483 has 4 optically isolated logic inputs which are located on connector P1. These inputs are isolated to minimize or eliminate electrical noise coupled onto the drive control signals. Each input is internally pulled-up to the level of the optocoupler supply and may be connected to sinking outputs on a controller such as the IMS LYNX or a PLC.
Powering the Optocouplers In order to maintain isolation, the optocouplers must be powered by an external power supply connected to P1:4, with the opto supply ground connected to the ground of the input control circuitry. The logic inputs are internally limited to allow for a +5VDC power supply. A power supply in excess of +5 volts may be used, however a current limiting resistor MUST be placed in series with the input to limit the input forward current to the recommended 7 milliamps.
Direction (P1:3) The direction input controls the CW/CCW direction of the motor. The direction of motion will depend upon the wiring of the motor phases. This input is synchronized to the positive going edge of the step clock input. Enable (P1:5) This input can be used to enable or disable the driver output circuitry. When in a logic HIGH (default, unconnected) state the driver outputs will be enabled and step clock pulses will cause the motor to advance.
Interface Methods The isolated logic inputs may be interfaced to the user’s control system in a variety of ways. In all cases the inputs are normally in a logic HIGH state when left floating. For purposes of this manual we will show three interface methods: 1] Switch Interface. 2] Open Collector Interface. 3] TTL Interface. We will also show IM483 inputs connected to the IMS LYNX modular motion controller, which is a powerful machine control soulution.
Open Collector Interface Figure 7.7 shows an open collector interface connected to the reset input. This interface method may be used with any of the logic inputs. Remember that a current limiting resistor is required if an opto supply voltage greater than +5 VDC is used. +VD C R L IM IT 5 10 12 15 24 ----681 1 0 00 1 3 00 2 6 70 +VDC O p to S u pp ly P 1:4 C O N T R O L LE R OUTPUT R L IM IT … W 1% Ω R e se t P 1 :6 L o w P u lse W ill R e se t D rive r Figure 7.

It has the capability of controlling up to three axes sequentially when used with the optional high speed differential I/O module. For more information on the LYNX, browse the IMS web site at www.imshome.com.
Connecting and Using the Fault Output The IM483 has an open collector fault output located on P1:7. This output is non-isolated and has the ability of sustaining maximum driver voltage. It can sink a maximum of 25mA, which is sufficient to drive an LED or a small relay. This output is active when in a LOW state. The following conditions will cause this output to become active: 1] Phase-to-phase short circuit. 2] Phase-to-ground short circuit. 3] Phase over-current condition.
Full Step Output The full step output is a high speed MOSFET (open drain) output located at P1:8. This output will toggle LOW each time the driver makes a full step, and remain so for the duration of the full step. A full step occurs each time the Phase A or Phase B sine wave crosses through zero. At zero crossing there will be full current in one motor winding, zero current in the other. This full step position is a common position regardless of the microstep resolution selected.

Appendix A Standard Connection Options Appendix Overview The IM483 has multiple connection options available to the user. In general, these options will not change the operational characteristics of the driver. These connector options give the user multiple choices in how to interface and mount the driver into a system. Listed below are the connector options and how they may be used. IM483-34P1 The IM483-34P1 features the standard 8 pin terminal block at the connector P2 location.
IM483-34P1 The IM483-34P1 connector configuration replaces the 8 position screw terminal at connector location P1 with a 34 pin header. Connector P2 is still an 8 position screw terminal. There are 2 key features that are added with this connector option: 1] Microstep resolution select inputs (MSEL) on P1 allow for remote control of the output resolution. 2] Step/Direction outputs follow the step/direction inputs, allowing for multiple drives to be cascaded. 0.100 (2.54) 0.230 (5.84) 8X 0.025 (0.
IM483-34P1 Connector P1 Configuration PIN # FUNCTION DETAILS 3 Resolution Select 3 4 Step Clock Input A positive going edge on this input advances the motor one increment. The size of the increment is dependent upon the settings of the resolution select switch SW1. 6 Direction Input This input is used to change the direction of the motor. Physical direction also depends upon the connection of the motor windings.
The Resolution Select (MSEL) Inputs One of the key features of the 34 pin header is the availability of the resolution select inputs on P1. This allows the user to take external control of the driver output resolution, enabling the user to switch the output resolution “onthe-fly”. An example would be to switch to a lower resolution (higher velocity, lower positional accuracy) during a long move.

Step Clock and Direction Outputs Another key feature offered by the IM483-34P1 is the non-isolated step clock and direction outputs. These outputs will follow the step and direction inputs. This allows for multiple drives to be cascaded, with the primary drive receiving the step/direction signals from the control device, and the drives connected to the step/direction outputs to follow the primary. Figure A.4 illustrates a possible connection/application of these outputs.
IM483-8P2 This connector option uses 8 - 0.045 square pins at the P2 connector location. The P1 connector location uses 8 -0.025 square pins. This connector style is advantageous in a scenario where the user desires to either solder the IM483 directly into a system PCB or wire-wrap the interface connections. Figures A.5 and A.6 show the pin dimensions. 8X 0.025 (0.64) Sq. Post Tin Plated Bronze 0.200 (5.08) 0.820 0.720 (20.83) (18.29) 8 Pin Connector Pins - P1 Applicable Products: IM483-8P2 Figure A.

IM483-34P1-8P2 This option combines the features and potential uses of the IM483-34P1 and the IM483-8P2. The connector pins used for connector P2 are identical to those used on the IM483-8P2. The difference between the P1 connector on this model and the standard IM48334P1 is in the pin height of the pin header shipped with the drive. There is no difference in the receptacle used. This option may be solder-mounted or the pins may be wire-wrapped for interfacing. 8X 0.025 (0.64) Sq.
