BASIC SAFETY INSTRUCTIONS
Switching at the output
Switching between motor and drive converter is prohibited for single drives during op-
eration as this may trigger the protection gear of the device. Function speed search must
be activated if switching can not be avoided. Control release may only be triggered after
closing the motor contactor (e.g. by switching the control release).
Connecting and disconnecting is permissible with multiple motor drives if at least 1 mo-
tor is running during the switch-over process. The drive converter must be dimensioned
to the occurring starting currents.
The speed search function must be activated if the motor is still running during a restart
of the drive converter (mains on) (e.g. due to large rotating masses).
