ABB UNS0880a-PV2 3BHB005922R0002 Redundant channel module

Disconnect the AC power. Disconnect motor cable and cycle the J1 120/240 Vac 60/50 Hz power Off and On. If the PROCESSOR FAULT LED is OFF, check motor cable and motor for shorts across the windings or between the windings and the motor case. Drive faults while decelerating. Drive internal bus over voltage. Measure drive internal bus voltage at J6-1 and J6-2 (66 Vdc Out) with a storage oscilloscope during deceleration. If regeneration causes the bus voltage to exceed 84 V, verify the system load inertia to insure that the 66 Vdc out limit is never exceeded.

Measure the +5 V Logic Supply at J7-4 to J7-1 and J10-7 to J10-6 within +5V (±5%). Note: The total 5 Vdc current from pins J7-4, J11-8 and J10-7 must be less than 450 mA.

 Communications Interface Faul

t Procedure Follow this procedure if the terminal does not communicate with the indexer/drive: SYMPTOM CORRECTIVE ACTION 6445 will not respond to commands over serial link Verify that baud rate and COM port are set correctly in PacCom. Check that terminal transmit and receive lines from computer go to receive and transmit lines on the 6445. (See Section 2.5.4) Verify that serial cable is functioning properly. 1. Disconnect serial cable. 2. Short pins2&3 (See Section 2.5.4) 3. Type a character on keyboard. 4. Verify that character entered echoes back to screen.

Return procedure
