2.8.11.21.2 Switching of a motor at the inverter output
Switching in the output is possible at any time. When switching on the running motor (inverter released), the motor
is captured in its current speed and brought back to the desired speed in accordance with the ramp-up time.
For this application, function "Capture in run" (
see "CATCH ON THE FLY (FLr-)" on page 290 ) must be configured
and the function for managing an existing motor protection must be enabled.
Typical applications:
•
Safety shutdown at the inverter output
• Bypass function
•
Operation motors connected parallel
For new installations it is recommended to use the safety function "power removal".
Note:
•
The control of the motor protection must be synchronized with a stop command in the freewheel
stop of the converter on e.g. a logic input/ POWERLINK.
•
Set the parameter [Output phase loss] (OPL) to [Outp. switch] (OAC) , if you are using an output
contactor.
