Start/Stop
Clockwise rotation FWD
If you activate a digital input which has been configured as a FWD
input, the motor starts to run in a clockwise direction. If you deac-
tivate the input, the motor coasts to a stop.
If the FWD and the REV inputs are activated simultaneously, the
motor coasts to a stop.
Anticlockwise operation: REV
If you activate a digital input which has been configured as an REV
input, the motor starts to run in an anticlockwise direction. If you
deactivate the input, the motor coasts to a stop.
Issue start command
By default, the start command is issued through the inputs confi-
gured as FWD or REV. If however, the start command is currently
issued via the ON key on the keypad, set under PNU A02 the value
01 (start command via FWD/REV input) (a Section ”Start
command”, Page 78).
X Program one of the digital inputs 1 to 5 as FWD by setting the
corresponding PNU (C01 to C05) to 00.
X Program one of the digital inputs 1 to 5 as REV by setting the
corresponding PNU (C01 to C05) to 01.

Warning!
If the supply voltage for the frequency inverter is applied
when the start signal is activated, the motor will start
immediately. Make sure, therefore, that the start signal is
not active before the supply voltage is switched on.
Warning!
If the FWD/REV input is opened (inactive state if FWD/REV
is configured as a make contact) and then it is reconfi-
gured as a break contact, it must be noted that the motor
will start immediately after the reconfiguration.
