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.

Status word according to Profidrive protocol
The status word is used to inform the master
(e.g. a PC) of the slave ’ s (frequency converter)
mode. Slave
⇒

Bit 00, Control not ready/ready:
Bit 00 = ’ 0 ’ means that the Bit 00, 01 or 02 in the
control word are ’ 0 ’ (OFF1, OFF2 or OFF3) or the
frequency converter is not ready for operation.
Bit 00 = ’ 1 ’ means that the frequency converter
is ready for operation.
Bit 01, Drive ready:
See description under Status word according
to FC protocol.
Bit 02, Coasting stop:
Bit 02 = ’ 0 ’ means that Bits 00, 02 or 03 in the control
word are "0" (OFF1, OFF3 or Coasting stop).
Bit 02 = ’ 1 ’ means that Bits 00, 01, 02 and
03 in the control word are "1", and that the
frequency converter has not tripped.
Bit 03, No trip/trip:
See description under Status word according
to FC protocol.
Bit 04, ON 2/OFF 2:
Bit 04 = ’ 0 ’ means that Bit 01 in the control word = ’ 1 ’ .
Bit 04 = ’ 1 ’ means that Bit 01 in the control word = ’ 0 ’ .
