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
⇒
Master.
Bit Bit = 0 Bit =1
00 Control ready
01 Drive ready
02 Coasting stop
03 No trip Trip
04 ON 2 OFF 2
05 ON 3 OFF 3
06 Start enable Start disable
07 Warning
08 Speed

OK
11 Motor running
12
13 Voltage warn.
14 Current limit
15 Thermal warn.
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 ’ .
Bit 05, ON 3/OFF 3:
Bit 05 = ’ 0 ’ means that Bit 02 in the control word = ’ 1 ’ .
Bit 05 = ’ 1 ’ means that Bit 02 in the control word = ’ 0 ’ .
Bit 06, Start enable/start disable:
Bit 06 = ’ 1 ’ after reset of a trip, after activation of OFF2
or OFF3 and after connection of mains voltage. Start
disable is reset by setting Bit 00 in the control word
to ’ 0 ’ , and Bit 01, 02 and 10 are set to ’ 1 ’ .
Bit 07, Warning:
See description under Status word according
to FC protocol.
Bit 08, Speed:

Bit 15, Thermal warning:
See description under Status word according
to FC protocol.

Serial communication reference
The serial communication reference is transferred to
the frequency converter as a 16-bit word. The value is
transferred in whole numbers 0 - ±32767 (±200%).
16384 (4000 Hex) corresponds to 100%.
The serial communication reference has the following
format: 0-16384 (4000 Hex) 0-100% (Par. 204
Minimum ref. - Par. 205 Maximum ref. ).
