4.3 Commissioning with control signal terminals (default settings)
DC1 variable frequency drives with local controls are configured and wired at
the factory. They can be started directly via the control signal terminals when
the rated motor output for the mains voltage is connected (see the
connecting example below).
Following are a series of simplified connecting examples that use the default
configuration:
NOTICE
Any contactors and switching devices on the power side are not
to be opened during motor operation. Inching operation using
the mains contactor is not permitted.
Contactors and switchgear (repair and maintenance switches)
on the motor side must not be opened while the motor is in
operation.
Inching operation of the motor with contactors and switching
devices in the output of the variable frequency drive is not
permitted.
NOTICE
Make sure that there is no danger in starting the motor. Discon-
nect the driven machine if there is a danger in an incorrect oper-
ating state.
￫
If motors are to be operated with frequencies higher than the
standard 50 or 60 Hz, then these operating ranges must be
approved by the motor manufacturer. The motors could be
damaged otherwise.
￫
You can skip this section if you want to set up the parameters
directly for optimal operation of the variable frequency drive
based on the motor data (rating plate) and the application.
