Requirement
WARNING
Unexpected motion as a result of an automatic hot restart
An activated automatic restart can initiate unexpected machine motion that may result in
death or sever injury.
• Only activate the automatic restart function if this cannot result in any dangerous situation.
• In the system or at the machine, clearly mark that the drive can automatically restart.
Description of function
p1210 activates the automatic restart function corresponding to the requirements of the
speci󹪝c application.
The automatic restart function includes 2 di󹪜erent subfunctions:
• The converter acknowledges faults automatically.
• After a fault or a power failure, the converter switches on the motor again automatically.
The converter interprets the following events as a power failure:
• The converter signals fault F30003 (undervoltage in the DC link) after the line voltage of the
converter was brie󹪞y interrupted.
• All power supplies of the converter were interrupted and all the energy storage devices in the
converter were discharged to such a level that the converter electronics failed.
For certain faults, p1206[0...9] suppresses the automatic restart.
The following diagram shows the principle of operation of the automatic restart function.
