Operating Manual

9.3.2 Automatic
Restart
Description
The automatic restart function automatically restarts the cabinet unit after an
undervoltage or a power failure. The alarms present are acknowledged and the
drive is restarted automatically. The drive can be restarted using the standard
procedure starting from standstill or using a flying restart. For drives with small
inertia loads and load torques where the drive can be brought to a standstill within
seconds (such as pump drives with water gauges), the start from standstill is
recommended. For drives with large inertia loads (such as fan drives), the flying
restart function can also be activated. This enables you to switch to the motor that
is still rotating.
WARNING
If p1210 is set to 2 or higher, the motor can be restarted automatically without the
need to issue the ON command.
In the event of prolonged power failures and when the automatic restart function is
activated (p1210 > 1), the drive may have been at a standstill for a long time and
mistakenly considered to have been switched off.
For this reason, entering the area around the drive when it is in this condition can
cause death, serious injury, or considerable material damage.
