1
Status Word
Sends the Status word from the frequency converter. The format depends of the setting of
par. 8-10.
2
Actual value
Sends actual output frequency in %. See section:
Bus speed reference Value.

input=high)
Bit 0: Input 33
Bit 1: Input 32
Bit 2: Input 29
Bit 3: Input 27
Bit 4: Input 19
Bit 5: Input 18
Bit 6-11: Reserved
Bit 12: Input DIN 1 (X25-1) on Interbus option
Bit 13: Input DIN 2 (X24-2) on Interbus option
Bit 14: Input DIN 3 (X24-3) on Interbus option
Bit 15: Input DIN 4 (X24-4) on Interbus option
4
Analogue input
Reads out analogue input 53 as an absolute value. Term.53 can work as a voltage (0-10V) or
a current (0-20mA) input, depending on the setting of S201.
S201=0 voltage, S201=1 current.

NB!
If the connection to the Interbus master is lost, all outputs on the Interbus option are set to 0.
NB!
Setting par. 8-10 to [1]
PROFIdrive profile
, enables the Drivecom Profile on the Interbus option, i.e. Control word and Status word are
interpreted as Drivecom.
Setting par. 8-10 to [0]
FC Profile
will enable the FC profile on the frequency converter.
See section
How to Control the FC 300
for more information on the different profiles.
NB!
If the Interbus option is powered up without connection to a FC300 frequency converter, it will run Standard Telegram 1. This means
that it will not be possible to use any I/O’s.
Examples
:
Setting the torque limit in PCD 4
(master slave):
→
Conversion index is -1.
500hex = 1280dec = 128% torque.
Reading the analogue input in PCD 4
(slave master):
→
Conversion index is -3.
3456dec = 3,456 volt.
