What To Do When an Alarm Trips
WARNING
If a protection trips or the drive is in emergency condition, the drive is locked and the
motor starts idling!
WARNING
Before resetting an alarm, press the emergency button to disable the drive and to prevent
the connected motor from running at uncontrolled speed.
Proceed as follows
:
1. Press the Emergency Button, as to deactivate the
ENABLE-A
and
ENABLE-B
signals on terminal
MDI2
and to disable the drive and to lock the motor, unless parameter

function is active): after resetting an alarm or after supplying the drive, this will start only if the
ENABLE-
A

Any information stored to the FAULT LIST is also required when contacting Enertronica Santerno
’s
Customer Service.
3. In the following sections, find the relative alarm code and follow the instructions.
4. Solve any external problems that may have been responsible for the protection trip.

6. Reset the alarm.
7. If the alarm condition persists, please contact Enertronica Santerno Customer Service.
