7.1 Wiring Function Loss For the unit to run, you must maintain a signal at the Function Loss input (the connection between control terminals 7 and 11). If the Function Loss signal is not present, the unit turns off the power devices and coasts to rest. To restart the unit, you must restore the Function Loss signal, clear any faults, and reassert the Start command. The unit ships from the factory with a jumper between terminals 7 and 11 which provides the Function Loss signal.
7.2 Wiring the Analog Output The analog output provides a 0 to 10 VDC signal to a user-supplied metering device. This output indicates speed (default) or %load (user option), based on the status of input terminal 12. If you select speed indication, 0 to 10 V = 0 to the maximum speed as defined by the maximum speed rotary switch. (Refer to chapter 8 for a description of the rotary switch.) If you select %load indication, 0 to 10 V = 0 to 200% load. Wire to the analog output as shown in figure 7.5.
7.3 Wiring the Relay Control Output A single form A relay on the terminal block can be used to indicate the unit is running (default) or has faulted (user option) based on the setup slide switch setting. Refer to the setup slide switch description in chapter 8. Wire to the relay control output as shown in figure 7.6.

7.4 Wiring RPM or %Load Display The RPM or %Load Display input (control terminal 12) selects the type of information displayed by the analog output and the built-in display, speed in RPM or %load. Wire a switch between control terminals 12 and 13 as shown in figure 7.7. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 %Load RPM RPM or %Load Display 24V DC Figure 7.7 – RPM or %Load Display Wiring 7.
7.5.1 Wiring the Preset Speed Inputs Control terminals 8, 9, and 10 select seven preset speeds as shown in table 7.1. Note that if you select a preset speed that is greater than the maximum speed setting (based on the rotary switch setting), the unit uses the maximum speed setting value. Important: Slide switch position 8 defines whether terminals 8, 9, and 10 are used as presets (default) or to define the unit’s minimum speed (user option). Refer to section 8.3.
7.5.2 Wiring the Speed Reference Signal Potentiometer Control terminal 1 provides a 10 VDC reference for use with the user-supplied 5 kΩ potentiometer. Perform the following procedure to wire the potentiometer as the speed reference (refer to figure 7.9): Step 1. Mount the speed reference potentiometer at an appropriate operator-accessible location, less than 300 meters (1000 feet) from the VSM500 unit. Step 2.
7.5.3 Wiring an External Speed Reference (0 to 10 VDC or 4 to 20 mA) The terminal block provides both 0 to 10 VDC and 4 to 20 mA inputs. Use only one of these inputs for the external speed reference. The other input must remain unconnected. 0 to 10 VDC External Speed Reference To use an external 0 to 10 VDC signal to set the speed reference, connect the signal leads as shown in figure 7.10. 0 to 10 VDC = minimum speed to maximum speed.
4 to 20 mA External Speed Reference To use an external 4 to 20 mA signal to set the speed reference, connect the signal leads as shown in figure 7.11. 4 to 20 mA = minimum speed to maximum speed. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 4 to 20 mA Speed Reference Input Common _ + 4 to 20 mA Figure 7.
7.6 Wiring Start / Stop Control Important: This applies only to standard units and local operator control units set up for terminal block control (setup slide switch position 9 = ON, see section 8.3.9). The system looks for an open-to-closed transition at the Start input before starting the unit unless you have the Power-Up Start switch (setup slide switch 1, see section 8.3.1) set to ON.
7.7 Wiring Forward / Reverse Control Important: This applies only to standard units and local operator control units set up for terminal block control (setup slide switch position 9 = ON, see section 8.3.9). The Forward / Reverse input (the connection between terminals 13 and 14) defines the requested direction of motor rotation. If the input is open, the requested direction is forward. Switching the Forward / Reverse input causes the motor to ramp to rest and then accelerate in the opposite direction.
7.8 Wiring Reset Control Important: This applies only to standard units and local operator control units set up for terminal block control (setup slide switch position 9 = ON, see section 8.3.9). An open-to-closed transition at the Reset input (control terminal 15) clears a fault once the appropriate corrective action has been taken. After clearing the fault, you must reassert the Start command in order to restart the unit. Wire a normally-open (N.O.
CHAPTER 8 Step 8 - Verify the Setup and Adjust Switches if Required The VSM500 unit is set up using two rotary switches and a 10-position slide switch mounted on the printed circuit board as shown in figure 8.1. Figure 8.1 shows the setting selections and the factory defaults. Normally, no adjustments will be needed to the factory settings. If your application requires adjustment to these settings, refer to the following sections in this chapter.
45 23 45 6 23 Max Speed Switch (SW2) 01 01 0 = 1500 RPM (50 Hz) 1 = 1800 RPM (60 Hz) (Default) 2 = 2100 RPM (70 Hz) 3 = 2400 RPM (80 Hz) 4 = 2700 RPM (90 Hz) 5 = 3000 RPM (100 Hz) 6 = 3300 RPM (110 Hz) 7 = 3600 RPM (120 Hz) 7 7 6 0 = 1 sec accel / 5 sec decel 1 = 5 sec (Default) 2 = 10 sec 3 = 15 sec 4 = 20 sec 5 = 30 sec 6 = 60 sec 7 = 90 sec Accel/Decel Switch (SW1) (See section 8.2) (See section 8.1) Setup Slide Switch (SW3) (See section 8.
8.1 Adjusting the Maximum Speed ! ATTENTION: The user is responsible for ensuring that driven machinery and all drive-train mechanisms are capable of safe operation at maximum speed. Failure to observe this precaution could result in severe bodily injury or loss of life. 6 7 01 45 The maximum speed rotary switch limits the speed reference to the unit. Regardless of what speed reference is supplied, the unit will not command a speed greater than the value selected by this rotary switch.
8.2 Adjusting the Acceleration / Deceleration Time 6 7 01 45 The acceleration / deceleration time is the amount of time it takes the motor to ramp from stop to the maximum speed setting of the unit. This is also the amount of time it takes the motor to ramp from the maximum speed setting to stop. 0 = 1 sec accel / 5 sec decel 1 = 5 sec (Default) 2 = 10 sec 3 = 15 sec 4 = 20 sec 5 = 30 sec 6 = 60 sec 7 = 90 sec Accel Time = the time required to accelerate from stop to MAX SPEED.
Step 3. Apply AC input power. Step 4. Set the desired operating speed. Standard units: Use the speed potentiometer or other user-supplied external speed reference device. Local operator control units: Use the key to increase the speed reference and the key to decrease the speed reference. Step 5. Repeat the adjustment procedure until the desired acceleration / deceleration time is obtained. Note that changes to the acceleration / deceleration time are recognized only while the drive is stopped.
8.3.1 Power-Up Start (Position 1) ! ATTENTION: Enabling this feature causes output power to be applied to the motor section automatically at drive power up. When this feature is enabled, the user must ensure that automatic start up of the driven equipment will not cause injury to the operating personnel or damage to the driven equipment.
8.3.3 Relay Control Output - Running or Faulted (Position 3) The switch at position 3 specifies the type of status indication provided by the normally open (N.O.) relay control output (control terminals 19 and 20). See section 7.3 for a description of control terminals 19 and 20. The relay can be used to indicate that the unit is running (power is applied to the motor section) or has faulted (an active drive fault exists).
Table 8.1 – Auto Restartable Faults Fault Code Description Overcurrent Overload High bus voltage Low bus voltage Overtemperature Settings (Position 4): OFF position = Auto-Restart Disabled (Default) ON position = Auto-Restart Enabled 8.3.5 Torque Curve (Position 5) The switch at position 5 selects either a variable torque curve or a constant torque curve. The variable torque selection provides a squared V/Hz curve and 110% electronic thermal overload and 110% current limit for one minute.
8.3.6 Stop Type (Position 6) The switch at position 6 selects how the motor will stop when the Stop input is asserted (or the red key is pressed). A coast-to-rest stop turns off the transistor power device drivers. A ramp-to-rest stop continues to switch the transistor power device drivers until the output frequency equals 0 Hz (decelerating the motor at a rate based on the accel / decel switch setting), and then turns off the power device drivers.
When the switch in position 8 is ON, the minimum speed will be determined as shown in the following table: Control Terminal Block Slide Switch Position 8 = ON Terminal 8 Status Terminal 9 Status Terminal 10 Status Minimum Speed Setting Open Open Open 0 RPM (0 Hz) Open Open Closed 150 RPM (5 Hz) Open Closed Open 300 RPM (10 Hz) Open Closed Closed 600 RPM (20 Hz) Closed Open Open 900 RPM (30 Hz) Closed Open Closed 1200 RPM (40 Hz) Closed Closed Open 1500 RPM (50 Hz) Closed C
8.3.9 Start Mode Select (Position 9) Important: This switch applies only to the local operator control units. The switch at position 9 is used to select whether the unit is controlled from the operator controls or from the terminal block. Note that if the unit is set up for terminal block control (Start Mode Select = ON), the and RESET keys remains active.
