Bit 02, DC brake
Bit 02 = "0" leads to direct voltage braking and
stop. Braking current and duration are set in
parameter 125 and 126.
Bit 02 = "1" results in
Ramp.
Bit 08, Activation of the fixed speed in parameter 213
In the case of bit 08 = "0", the fixed speed
will not be activated.
In the case of bit 08 = "1", the motor runs
at the fixed speed.
Bit 09, Ramp selection 1/2
In the case of bit 09 = "0", ramp 1 is active
(parameter 207/208).
In the case of bit 09 = "1", ramp 2 is active
(parameter 209/210).
Bit 11, Relay 01
Bit 11 = "0": Relay 01 is not activated.
Bit 11 = "1": Relay 01 is activated, on the pre-condition
that Control word bit was selected in parameter 323.
Bit 12, Relay 04
Bit 12 = "0": Relay 04 is not activated.
Bit 12 = "1": Relay 04 is activated, on the pre-condition
that Control word bit was selected in parameter 326.
NB!:
The description of the other bits can
be found in the section "Control word
according to Profidrive".
