4.3 Commissioning with control signal terminals (default settings)
The controls on DA1 variable frequency drives are pre-wired at the factory;
however, the STO inputs need to be wired. After the mains voltage and the
rated motor are connected, the DA1 variable frequency drive can be started
with the local controls (see following connection example).
The following shows a simplified connecting example of a connection with
default settings.
WARNING
Any contactors and switching devices on the mains side are not
to be opened during motor operation.
Push-to-run 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.
Push-to-run operation of the motor with contactors and
switching devices in the output of the variable frequency drive is
not permissible.
WARNING
Make sure that there is no danger in starting the motor.
Disconnect the driven machine if there is danger resulting from
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.
