Internal Drive Faults
A fault is a condition that stops the drive. There are two fault types.
Table 11 Internal Drive 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 192 [Auto Rstrt Tries] to a value other than 0.
2. Set 193 [Auto Rstrt Delay] to 0.
Auto Restart (Reset/Run)
The Auto Restart feature provides the ability of 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, and Parameter 192 (Auto Rstrt Tries) Related Parameter(s):
155, 158, 161, 193 is set to a value greater than 0, a user-configurable timer,
Parameter 193 (AutoRstrt Delay) 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
programming errors. The cause of the fault must be corrected before the fault can be
cleared.
