AUTORESET MENU

O
VERVIEW
The Autoreset function can be enabled in case an alarm trips. You can enter the maximum number of
autoreset attempts and the time required for resetting the attempt number. If the Autoreset function is disabled,
you can program an autoreset procedure at power on, which resets an active alarm when the drive is shut off.
Undervoltage alarms or mains loss alarms can be saved in the fault list in the Autoreset menu.
To activate the Autoreset function, set a number of attempts other than zero in parameter C255. If the number
of attempts reset within a time interval t < C256 is equal to the value set in C255, the autoreset function is
disabled; it will be enabled again only when a time longer than or equal to C256 has passed.
If the drive is turned off when an alarm is active, the alarm tripped is stored to memory and will be active at
next power on. Regardless of the Autoreset function setup, an automatic reset of the last alarm stored can be
obtained when the drive is next turned on (C257 [Yes]).
