10.1.1 Manually Clearing Faults
Step 1. Note the number of the fault code flashing on the display.
Step 2. Address the condition that caused the fault. Refer to table
10.1 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
using one of the following methods:
• Press if P037 (Stop Mode) is set to a value
between 0 and 3.
• Cycle drive power.
• Set A100 (Fault Clear) to 1.
• Cycle digital input if A051-A054 (Digital Inx Sel) is set
to 7 = Clear Fault.
10.1.2 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 or
“unattended” operation. This feature can only be used for auto-
resettable faults (see table 10.1).
When this type of fault occurs, and Auto Rstrt Tries (A092) is set to
a value greater than 0, a user-configurable timer, Auto Rstrt Delay
(A093), 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.
To automatically clear an auto-resettable fault and restart the
drive:
Step 1. Set A092 (Auto Rstrt Tries) to a value other than 0.
Step 2. Set A093 (Auto Rstrt Delay) to a value other than 0.
To automatically clear an OverVoltage, UnderVoltage, or
Heatsink OverTemp fault without restarting the drive:
Step 1. Set A092 (Auto Rstrt Tries) to a value other than 0.
Step 2. Set A093 (Auto Rstrt Delay) to 0.
Use caution when enabling this feature since the drive will attempt
to issue its own start command based on user-selected
programming.
