Safety Notice: This equipment contains voltages that may be as great as 1000 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.
WARNING: Motor circuit may have high voltage present whenever AC power is applied, even when motor is not rotating. Electrical shock can cause serious or fatal injury. WARNING: Dynamic brake resistors may generate enough heat to ignite combustible materials. Keep all combustible materials and flammable vapors away from brake resistors. Caution: Disconnect motor leads (T1, T2 and T3) from control before you perform a “Megger” test on the motor.
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 (seeTable 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 Descriptions Five failure conditions are indicated by LED’s on the front panel. Carefully examine all LED’s (Power, Fault, FWD, REV and Stop) to determine the cause of the fault condition. Press Stop to reset the control. 1. Non Resettable hardware faults (Power LED is blinking) (HW Surge Current, HW Protect, Power Module faults) Power LED Fault LED Description Blinking 1 Blink Hardware fault is detected. High output current, or control board power supply failure. a.
3. Bus faults (Over-voltage, Under-voltage or Precharge faults) Power LED Fault LED Description ON 3 blinks High or low DC bus voltage is detected or DC Bus charging error detected. 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. Use step down transformer if needed.
