Resetting drive detected fault in Local Mode
It is not possible to clear a drive detected fault if the cause of the detected fault persists. Be certain to diagnose
and rectify the cause of the detected fault before attempting a drive reset.
With the STOP Key
To clear a drive detected fault in local mode:
1. Press the STOP key. See Fault detection codes that can be cleared with the automatic restart function after
the cause has disappeared on page 124
for a list of detected faults that can be cleared with the STOP key. If it
is possible to reset the drive, the embedded display terminal will display CLr.
2. To clear the detected fault, press the STOP key a second time.
3. If the cause of the detected fault is still present, the CLr display will not appear. Diagnose and clear the
detected fault before attempting to reset the drive.
Use of the STOP key as a clear detected fault can be set with parameter [HMI reset button] (F735) (see page
80
).
In the event of an OL1 or OL2 detected fault, the following time periods are necessary before a clear detected
fault is possible:
z OL1 (drive overload)—about 30 seconds after the detected fault has occured
z OL2 (motor overload)—about 120 seconds after the detected fault has occured
By Cycling Line Power
A drive detected fault can also be cleared by removing and restoring line power. Be certain that the cause of the
detected fault is no longer present and leave power removed long enough for all of the LEDs on the face of the
drive to extinguish.
Cycling power to clear a detected fault can cause the detected fault history to be lost. Refer to parameter [Drive
Fault Memory] (F602) on page 127
.

The logic input functions listed in the table below are active, even if [Command mode sel] (CMOd) is set to 1
(embedded display terminal control). See table on page 90
