Section 1 General Information Introduction The Baldor digital three phase multipurpose soft–starter provides reduced voltage, three phase motor starting and control over the four periods of motor operation. First, at “Start–up” (soft–start), the motor starting voltage increases from an initial preset level to full motor voltage to provide smooth motor acceleration to full speed. Second, the “Dwell” period begins when maximum motor voltage is achieved.
Safety Notice This equipment contains voltages that may be as high as 600 volts! Electrical shock can cause serious or fatal injury. Only qualified personnel should attempt the start-up procedure or troubleshoot this equipment. This equipment may be connected to other machines that have rotating parts or parts that are driven by this equipment. Improper use can cause serious or fatal injury. Only qualified personnel should attempt the start-up procedure or troubleshoot this equipment.
Section 2 Installation Receiving, Inspection and Storage When you receive your control, there are several things you should do immediately. 1. Observe the condition of the shipping container and report any damage immediately to the commercial carrier that delivered your control. 2. Remove the control from the carton. Inspect for shipping damage and report any damage immediately to your commercial carrier. 3.

Section 1 General Information Optional Remote Keypad Installation The keypad may be remotely mounted using optional Baldor keypad extension cable. Keypad assembly (white - DC00005A-01; gray - DC00005A-02) comes complete with the screws and gasket required to mount it to an enclosure. When the keypad is properly mounted to a NEMA Type 4X enclosure, it retains the Type 4X rating.
AC Main Circuit Power Disconnect A power disconnect should be installed between the input power service and the control for a fail safe method to disconnect power. Protective Devices Recommended fuse sizes are based on the following: 175% of maximum continuous current for time delay. 300% of maximum continuous current for Fast or Very Fast action. Note: These general size recommendations do not consider harmonic currents or ambient temperatures greater than 40°C.
UL Required Fuses for Short Circuit Rating UL requires R/C fuses, special purpose fuses (JFHR2) or semiconductor fuses rated 700VAC be used to obtain the short circuit current ratings required by UL.

NEMA 12/4 Installation When a NEMA12, NEMA4, NEMA4x OR IP65 enclosure is used, a separate Top of Ramp Bypass (or shunt) contactor must be connected in parallel with the soft–start control. This will allow a solid connection of the motor to the AC power lines and eliminate the heating effect caused by the SCR’s. At the completion of the start ramp (when full start voltage is obtained) a Bypass contactor is closed. This contactor is controlled by the “Top of Ramp” relay K2.
Reversing Contactor For this mode, the Stop Time must be set to zero. Also, allow a minimum of 350 milli seconds between the Forward and Reverse commands. Figure 2-7 Motor Reversing Connection To AC Input Forward Contacts Reverse Contacts MI To protect the control, be sure to add MOV protection. Refer to Appendix D for additional information.
Installation 1. Remove cover. (See cover removal described previously in this section.) 2. Mount the panel or enclosure to the mounting surface. The panel or enclosure must be securely fastened to the mounting surface. Refer to the mounting dimensions in Section 6 of this manual. Shock Mounting If the control will be subjected to levels of shock greater than 1G or vibration greater than 0.5G at 10 to 60Hz, the control should be shock mounted. 3.
Section 3 Operation Overview The start–up procedure will help get your system up and running quickly and will allow motor and control operation to be verified. This procedure assumes that the Control and Motor are correctly installed (see Section 2 for procedures) and that you have a basic understanding of the keypad programming & operation procedures. 1. Read the Safety Notice and Precautions in section 1 of this manual. 2. Mount the control. 3.
Start–Up Procedure This procedure assumes that this is the first time the control and motor have been started. The normal start–up procedure would be as follows: 1. Apply X1, X2 Control Voltage power (115VAC). 2. Apply three phase power. The display should show “Stopped & Ready”. 3. Press ENTER and the display should show “Applications”. 4. Press ENTER and the display should show “Settings”. 5. Press the UP or DOWN Arrows and select the desired type of motor load. 6.

Section 5 Troubleshooting Safety Notice Be sure to read and understand all notices, warning and caution statements in Section 1 of this manual. If you have any questions about the safe operation of this equipment, please contact your Baldor representative before you proceed. Preliminary Checks In the event of trouble, disconnect all input power to the control and perform these preliminary checks. Power Off Checks 1. 2. 3. 4. 5. Check all connections for tightness and signs of overheating.
Table 5-2 Troubleshooting Guide INDICATION Unit fails to start CORRECTIVE ACTION LED’s on control card are OFF and no error messages displayed: 1. Verify that 115VAC is present at X1 and X2 terminals. 2. Verify that 9VAC is present at terminal J2 (see Section 2 cover removal). Green power LED is ON and no error messages displayed: 1. Control board or other component may be defective. Contact Baldor. Unit trips during start 1.
Table 5-2 Troubleshooting Guide Continued INDICATION Initial motor kick then bad start CORRECTIVE ACTION Verify that AC input power and motor power wires are not reversed. (The motor will give an initial kick then start very roughly.) Current is not displayed 1. Verify the current transformer connections at J3 control terminal. 2. Verify that the soft–start control is correctly sized. Motor does not accelerate 1. Verify the Current Limit parameter value and increase if necessary. 2.
Electrical Noise Considerations All electronic devices are vulnerable to significant electronic interference signals (commonly called “Electrical Noise”). At the lowest level, noise can cause intermittent operating errors or faults. From a circuit standpoint, 5 or 10 millivolts of noise may cause detrimental operation. For example, analog speed and torque inputs are often scaled at 5 to 10VDC maximum with a typical resolution of one part in 1,000. Thus, noise of only 5 mV represents a substantial error.

Appendix A CE Guidelines CE Declaration of Conformity Baldor indicates that the products are only components and not ready for immediate or instant use within the meaning of “Safety law of appliance”, “EMC Law” or “Machine directive”. The final mode of operation is defined only after installation into the user’s equipment. It is the responsibility of the user to verify compliance.
Using CE approved components will not guarantee a CE compliant system! 1. The components used in the drive, installation methods used, materials selected for interconnection of components are important. 2. The installation methods, interconnection materials, shielding, filtering and grounding of the system as a whole will determine CE compliance. 3. The responsibility of CE mark compliance rests entirely with the party who offers the end system for sale (such as an OEM or system integrator).
EMC Installation Instructions To ensure electromagnetic compatibility (EMC), the following installation instructions should be completed. These steps help to reduce interference. Consider the following: • Grounding of all system elements to a central ground point • Shielding of all cables and signal wires • Filtering of power lines A proper enclosure should have the following characteristics: A) All metal conducting parts of the enclosure must be electrically connected to the back plane.

Appendix D Voltage Surge Protection Grounding Proper grounding is extremely important. The symptoms produced by improper grounding are obvious. Sometimes filters and other expensive devices are added to reduce the effects of problems caused by poor grounding. There can be several reference points (neutrals) in a circuit but there should always only be one ground point. Neutral and ground are not the same.
