Note:
This configuration has been obtained from a drive with
factory settings (default parameter settings).
The STO-1 and STO-2 inputs must be closed before giving a
run command.
(*) If the motor thermal sensor needs to be connected to DI1/
PTC, set
Mtr.06 (05.70)
= Drive terminal (1).
(**) If the 2 STO inputs are not in the same status, the relay
