ABB UNC4611b V2 HIER460378R3 Pulse output card

1  Enable the 6445 (connect input pin 5 to pin 6 on J10). 2. Verify that the motor has holding torque by attempting to rotate the motor shaft. The energized motor shaft is either immovable or very resistant to rotation when the 6445 is enabled. 3. Jog the motor (connect input pin 7 to pin 9 on J8 ). The motor moves at the default jog speed. 4. Remove the jog input. 5. From the terminal or computer, type GO.VEL. This moves the motor at the default run speed. 6. Type DIR = 1. This changes the default direction (if DIR = 0 was the initial setting). Repeat Step 5. The motor should run in the reverse direction. 7. Continue exercising the unit, testing it in your application If you need further help with your installation, contact Pacific Scientific at 978-988-9800 from 8 a.m. to 5 p.m. Eastern Standard Time, or contact your Pacific Scientific distributor.

The LEDs located on the front panel indicate unit status 

and are useful for troubleshooting. A table of the LEDs referencing the appropriate section for troubleshooting is located below. Fault output The fault output is located on pin 8 of the J10 connector. This output is active when the unit is enabled and no fault condition is present Check 66 Vdc Out @ J6-1, J6-2. If voltage is within operational range, then it is an internal failure. If not, then check AC input is applied and within operational range. 240 Vac applied and switch in 120 Vac position. Return to factory for service.

Fuse replacement 

If an open fuse is suspected, replace the fuse as follows. Usually a fuse failure indicates a problem requiring factory repair. 1. Remove power and wait five minutes to allow the charge on the capacitors to dissipate. WARNING Do not operate the unit with the cover removed. Contact with energized components causes severe shock or burn. 2. Remove the 4 phillips-head screws located on the sides of the 6445. 3. Using a nutdriver, remove the 2 jacknut screws on J7. 4. Remove the cover. CAUTION Be careful not to put a strain on the ribbon cable when removing the cover. 5. Check the fuse F1 located by the J1 120/240 Vac connector. Replace open fuse with a 5 A, 250 Vac SLO-BLO fuse. 6. Replace the cover.
