4.3 Commissioning with control signal terminals (default settings)
The controls on DA1 variable frequency drives are pre-wired at the factory;
however, you will need to wire the STO inputs yourself. After the mains
voltage and the rated motor are connected, the DA1 variable frequency drive
can be started with the local controls (see following connecting example).
The following shows a simplified connecting example of a connection with
default settings.
NOTICE
Any contactors and switchgear on the power side are not to be
opened during motor operation. Inching operation using the
power switch 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
permissible.
NOTICE
Make sure that there is no danger in starting the motor.
Disconnect the driven machine if there is a danger in an
incorrect operating 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.
