Section 2 General Information CE Compliance A custom unit may be required, contact Baldor. Compliance to Directive 89/336/EEC is the responsibility of the system integrator. A control, motor and all system components must have proper shielding, grounding and filtering as described in MN1383. Please refer to this manual for installation techniques for CE compliance.
WARNING: Do not use motor overload relays with an automatic reset feature. These are dangerous since the process may injure someone if a sudden or unexpected automatic restart occurs. If manual reset relays are not available, disable the automatic restart feature using external control wiring. WARNING: This unit has an automatic power up start feature that will start the motor whenever input power is applied and a RUN (FWD or REV) command is issued and maintained.
Section 3 Receiving and Installation Receiving & Inspection The Series 15P Inverter control is thoroughly tested at the factory and carefully packaged for shipment. 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. Verify that the control you received is the same as listed on your purchase order. 3.
Control Installation The control must be securely fastened to the mounting surface. Use the four (4) mounting holes to fasten the control to the mounting surface or enclosure. 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. Excessive vibration within the control can cause internal connections to loosen and could lead to component failure or electrical shock hazard.
Cover Removal The cover is made of plastic and could be damaged during removal if handled roughly. Refer to Figure 3-1. Insert a screw driver or small blade tool and pry the cover outward as shown to release the side. When both sides are released, remove the cover. Figure 3-1 Cover Removal Use small screw driver or suitable tool to pry cover slightly outward to release cover from its catch. Use small screw driver or suitable tool to pry cover slightly outward to release cover from its catch.
AC Line Connections A power disconnect should be installed between the input power service and the control for a fail-safe method to disconnect power. The control will remain in a powered-up condition until all input power is removed from the control and the internal bus voltage is discharged. Protective Devices Recommended fuse sizes are based on the following: 115% of maximum continuous current for time delay. 150% of maximum continuous current for Fast or Very Fast action.

Motor Brake Connections For motors with spring set brakes, connect the brake power leads and the motor power leads separately. Because the inverter has variable voltage output to the motor, the inverter may not supply enough power at low frequencies for proper brake operation. If using a motor with an internally connected brake, the brake power leads must be connected to a separate power source for proper brake operation. Refer to Figure 3-2 for terminal locations.
Analog Input (S1-7 = OFF) If S1-7 is OFF, the front panel % Speed potentiometer is selected. The J4 inputs are ignored. (S1-7 = ON) One analog input is available at J4-2 and J4-1 as shown in Figure 3-7. The input may be connected to a potentiometer as shown or an input signal can be applied to pin J4-2. The analog signal can be 0-10VDC or 4-20 mA as selected by S1–6 (see Table 3-5). Note: A potentiometer value of 5k to 10k , 0.5 watt may be used.
Digital Inputs (S1-8 = OFF) If S1-8 is OFF, the front panel commands FWD, REV and STOP are selected. The J4 inputs are ignored. (S1-8 = ON) Three inputs are available on the J4 connector. Switch S1-5 determines whether two wire or three wire operation is used. If two wire is selected (S1-5= OFF) the STOP input at J4-6 is not used. Note: Pressing the STOP switch on the front panel keypad will override the J4 commands and cause the motor to decel to a stop.

Section 5 Troubleshooting The Baldor Series 15P Control requires very little maintenance, if any, and should provide years of trouble free operation when installed and applied correctly. Occasional visual inspection to ensure tight wiring connections and cleaning to remove dust, dirt, or foreign debris which can reduce heat dissipation should be considered. Operational failures called faults are displayed on the LED’s as they occur.
Fault Code 1 – Non Resettable hardware fault (Power LED is blinking). May indicate a HW Surge Current, HW Protect or a Power Module fault is detected. Power LED Blinking Fault LED 1 Blink Action a. Check wiring to ensure a ground fault is not present. b. Make sure the load is not excessive. Fault Code 2 – 2 or 60 second Overload or a % Overload Timer fault. 2 or 60 Second Overload May indicate an overcurrent condition but the control has not tripped, the FWD or REV LED is blinking.
Fault Code 3 – Bus faults. May indicate an Over-voltage, Under-voltage or Precharge fault was detected. Power LED ON Fault LED 3 blinks Action Press Stop to reset the control. If error remains, try these steps to correct the fault. a. Lengthen DECEL time (P2). b. Add external dynamic braking assemblies. c. Correct problem with motor load. d. Check dynamic brake hardware wiring. e. Verify proper AC line voltage. May need step down transformer or line reactor. f.
