Autoreset Configuration
The Autoreset function allows the automatic restoring of the driveoperation, after the detection of some alarms.
It will be active only with an appropriate setting of the parameters described below and after the drive has tripped from
one of the following alarms:
• undervoltage (UV)
• overvoltage (OV)
• overcurrent (OC)
• overcurrent desat (OCH)
• external fault (programmable) (EF)
• serial time out (St)
P.380 Autoreset attmps (Autoreset attempts)
Setting of the maximum number of autoreset, after the detection of an alarm. If P.380 is set to 0 the function is
disabled.
P.381 Autoreset clear
If enabled, it sets to zero the counter of the already-performed autoreset attempts, if no alarm condition is
detected within a period of time set in the P.381 Autoreset clear parameter. After the counter zero setting, the
number of the available restart attempts is set in the P.380 Autoreset attmps parameter. If P.381 Autoreset
clear is set with 0, the counter zero setting is not performed.
P.382 Autoreset delay
Delay that elapses between the failure detection and the beginning of the autoreset sequence.
