Internal Drive Faults

A fault is a condition that stops the drive. There are two fault types.

Table 9 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

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.

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.
