Bit 00-01-02, OFF1-2-3/ON1-2-3:
Bit 00-01-02 = '0' causes ramp stop, which uses the ramp time in pa-
rameters 207/208 or 209/210.
If
Relay 123
is selected in parameter 323
Relay output
, the output relay
will be activated when the output frequency is 0 Hz.
Bit 00-01-02 = '1' means that the frequency converter can start the motor
if the other starting conditions are fulfilled.

Catch-up/slow-down reference
.
Bit 12 = '0' does not cause any change to the reference.
