Internal Drive Faults
A fault is a condition that stops the drive. There are two fault types.
Automatically Clearing Faults (Option/Step)
Clear a Type 1 Fault and Restart the Drive:
1. Set Parameter 192 (Auto Rstrt Tries) to a value other than 0.
2. Set Parameter 193 (Auto Rstrt Delay) to a value other than 0.
Clear an Overvoltage, Undervoltage or Heatsink OvrTmp Fault without
Restarting the Drive:
1. Set Parameter 192 (Auto Rstrt Tries) to a value other than 0.
2. Set Parameter 193 (Auto Rstrt Delay) to 0.
Auto Restart (Reset/Run)
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. Only certain faults are
allowed to be reset. Certain faults (Type 2) that indicate possible drive
component malfunction are not resettable. Caution should be used when
enabling this feature, since the drive will attempt to issue its own start command
based on user selected programming.
Type Description
1 Auto-Reset/Run
When this type of fault occurs, Parameter 192 (Auto Rstrt Tries) and related
Parameter(s): 155, 193 are set to a value greater than 0, a user-configurable timer,
Parameter 193 (Auto Rstrt Delay) and related Parameter(s): 192, 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
2 Non-Resettable
This type of fault may require drive or motor repair, or is caused by wiring or
programing errors. The cause of the fault must be corrected before the fault can be
cleared.
