Troubleshooting the Drive
In this troubleshooting section, “check” means investigating whether an item is functioning and in an
acceptable physical condition, and then taking corrective action (adjusting, fixing, replacing, etc.) as
necessary. In the Corrective Action column, you may not have to perform all of the steps to correct
the problem.
Maintenance and Inspection
This section describes basic maintenance and inspection procedures for the IMPULSE•G+ Mini.
Alarm and Fault classes are described as follows:
•
Major Fault: Brake is set, ALM indicator LED remains lit, fault is displayed on keypad and
brake contact output (terminals MC, MB, & MA) is deactivated. In order to continue operation
the reset key must be pressed, a multi-function input set for fault reset or power must be cycled.
•
Fault (minor): Brake is set, ALM/indicator LED flashes, fault code flashes in the keypad brake
contact output (terminals MC, MB, & MA) is deactivated. The reset key does not need to be
pressed. The drive will attempt to run again at the next run command.
•
Alarm (Warning): Brake does not set, operation continues, ALM/indicator LED flashes, fault
code flashes, brake contact output (terminals MC, MB, & MA) stay activated.
