Control word according to Fieldbus Profile
To select Profidrive in the control word, parameter 512
Telegram Profile must be set to Profidrive [0].
The control word is used to send commands
from a master (e.g. a PC) to a slave (frequency
converter). Master
⇒
Slave.

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
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.
Bit 03, Coasting stop:
See description under Control word according
to FC protocol.
Bit 04, Quick stop:
See description under Control word according
to FC protocol.
Bit 05, Freeze output frequency:
See description under Control word according
to FC protocol.
Bit 06, Ramp stop/start:
See description under Control word according
to FC protocol.
Bit 07, Reset:
See description under Control word according
to FC protocol.
Bit 08, Jog 1:
Bit 08 = "1" means that the output frequency is
determined by parameter 09 Bus jog 1 .
Bit 09, Jog 2:
Bit 09 = "1" means that the output frequency is
determined by parameter 510 Bus jog 2 .
Bit 10, Data not valid/Data valid:
See description under Control word according
to FC protocol.
Bit 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 reference.
Bit 11 = ’ 1 ’ means that the reference is reduced.
Bit 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 reference.
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.
Bit 13/14, Selection of Setup:
See description under Control word according
to FC protocol.
Bit 15 Reversing:
See description under Control word according
to FC protocol.
