9-4 VS1-MD AC Drive User Manual
9.5.1 Manually Clearing Faults
Step 1. Note the code of the fault condition on the display.
Step 2. Address the condition that caused the fault. Refer to table 9.1 for a
description of the fault and corrective actions. The cause must be corrected
before the fault can be cleared.
Step 3. After corrective action has been taken, clear the fault and reset the drive.
9.5.2 Automatically Clearing Faults (Auto Restart Feature)
The Auto Restart feature provides the ability for the drive to automatically perform a
fault reset followed by a start attempt without user or application intervention. This
allows remote operation. This feature can only be used for faults that are
auto-resettable.
When this type of fault occurs, and H26 (Auto Restart) is set to a value greater than 0,
a user-configurable timer, H27 (Retry Delay) begins. When the timer reaches zero, the
drive attempts to automatically reset the fault. If the condition that caused the fault is
no longer present, the fault will be reset and the drive will be restarted.
