Gate Disable Alarm (59):

Configured by setting bit 15 “Gate Disable” of parameter 259 [Alarm
Config1].

If both digital inputs open, the drive output will be disabled and the motor
will coast to a stop. The drive HIM will display alarm 59 “Gate Disable”.

When the condition is cleared, the alarm will automatically clear in 10
seconds and the drive can be restarted.

If only one digital input opens, the drive output will be disabled and the
motor will coast to a stop. See

for a description of

drive conditions and actions.

Neither of the “Gate Disable” bits, 10 in parameter 238 [Fault Config1] or
15 in parameter 259 [Alarm Config1], are set.

If both digital inputs open, the drive output will be disabled and the motor
will coast to a stop. No fault or alarm indication will be given, but the Gate
Disable status can be seen in bit 0 “Gate Disable” of parameter 359 [20C-
DG1 Status].

When the condition is cleared, the drive can be restarted after 3 seconds.

If only one digital input opens, the drive will be disabled and the motor
will coast to a stop. See

The Gate Disable fault takes precedence.

Thermistor Input:

If the thermistor input goes out of range, the drive output will be disabled
and the motor will coast to a stop. The drive will display fault 60 “Hrdwr
Therm” on the drive HIM.

When the condition is cleared, the fault can be reset and the drive can be
restarted. This configuration requires that the two digital inputs remain
closed to function.
