Test
6. Perform any necessary parameter adjustments and start the drive. Confirm
that the drive stops and starts normally, then start and slowly accelerate the
motor.
7. Open Digital Input 6. The drive should stop and the motor coast to rest.
The HIM/OIM should indicate that the drive is “Not Enabled.”
8. Close Digital Input 6. The drive should not start but the HIM/OIM
should indicate that the drive is “Stopped.”
9. Provide the command to restart the drive. In the case of a maintained start,
remove and reapply the start command. In either case the drive should run
normally.
10. With the motor running, open Digital Input 5. The drive should stop and
the motor coast to rest. The HIM/OIM should indicate that the drive is in
an “Auxiliary Input” fault condition.
11. Close Digital Input 5. The drive should not start and the HIM/OIM will
continue to indicate an “Auxiliary Input” fault condition.
12. Provide the command to restart the drive. In the case of a maintained start,
remove and reapply the start command. In either case the drive should
remain stopped and in a fault condition.
13. Provide a Fault Reset command to the drive. The drive fault should clear.
The drive should not start even if a maintained start is applied when the
fault is reset.
14. Provide the command to restart the drive. In the case of a maintained start,
remove and reapply the start command. In either case the drive should run
normally.
15. Stop the drive, and disconnect all power from the drive including external
control power.
16. Disconnect the test switching devices from the two digital inputs.
17. Determine a way to interrupt the continuity of the over temperature
circuit when it is reconnected to the motor.
18. Properly reconnect the motor over temperature contact connection to the
drive and include the test mechanism to interrupt the over temperature
circuit’s continuity. This includes both Digital Input 6 (terminal 32) and
the additional required digital input. Reconnect the jumper between the
two inputs if one had been in place.
19. Reconnect power to the drive including external control power.
20. Start drive and confirm that it is operating properly.
21. Interrupt the continuity of the over temperature circuit connected to the
drive. The drive should stop and the motor coast to rest. The HIM/OIM
should indicate that the drive is in an Auxiliary Input fault condition.
IMPORTANT The drive should not start when closing Digital Input 6 even if a maintained
start command is present and had not been removed when the drive stopped.
