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

B
it 08, Jog 1:
Bit 08 = "1" means that the output frequency is de-
termined by parameter 09 Bus jog 1.
B
it 09, Jog 2:
Bit 09 = "1" means that the output frequency is de-
termined by parameter 510 Bus jog 2.
B
it 10, Data not valid/Data valid:
See description under Control word according to FC
protocol.
B
it 11, Slow-down:
Used to reduce the speed reference by the value in
parameter 219 Catch-up/slow-down reference.
Bit 11 = ’0’ does not cause any change to the refer-
ence.
Bit 11 = ’1’ means that the reference is reduced.
B
it 12, Catch-up:
Used to increase the speed reference by the value in
parameter 219 Catch-up/slow-down reference.
Bit 12 = ’0’ does not cause any change to the refer-
ence.
Bit 12 = ’1’ means that the reference is increased.
If both Slow down and Catch-up are activated (Bits
11 and 12 = "1"), slow down has the highest priority,
i.e. that the speed reference is reduced.
