FCD Series
Bit 09 = 0 means that ramp 1 is active (parameters
207/208). Bit 09 = 1 means that ramp 2 (parame-
ters 209/210) is active.
B
it 10, Data not valid/Data valid:
Is used to tell the frequency converter whether the
control word is to be used or ignored. Bit 10 = 0
causes the control word to be ignored, Bit 10 = 1
causes the control word to be used. This function is
relevant, because the control word is always con-
tained in the telegram, regardless of which type of
telegram is used, i.e. it is possible to turn off the
control word if you do not wish to use it in connec-
tion with updating or reading parameters.
B
it 11, No function:
Bit 11 has no function.
B
it 12, No function:
Bit 12 has no function.
B
it 13/14, Selection of Setup:
Bits 13 and 14 are used to choose from the four
menu Setups according to the following table:
Setup Bit 14 Bit 13
100
201
310
411
The function is only possible when Multi-Setups is
selected in parameter 004 Active Setup.
Note: I parameter 507 Selection of Setup a selection
is made to dene how Bit 13/14 gates with the corre-
sponding function on the digital inputs.
B
it 15 Reversing:
Bit 15 = 0 causes no reversing.
Bit 15 = 1 causes reversing.
Note: In the factory setting reversing is set to digital
in parameter 506 Reversing. Bit 15 only causes re-
versing when either Ser. communication, Logic or or
Logic and is selected.

Bit 00, Control ready:
Bit 00 = 1. The frequency converter is ready for op-
eration.
Bit 00 = 0. The frequency converter is not ready for
operation.
B
it 01, Drive ready:
Bit 01 = 1. The frequency converter is ready for op-
eration, but there is an active coasting command via
the digital inputs or via serial communication.
B
it 02, Coasting stop:
Bit 02 = 0. The frequency converter has released
the motor.
Bit 02 = 1. The frequency converter can start the
motor when a start command is given.
B
it 03, No trip/trip:
Bit 03 = 0 means that the frequency converter is
not in fault mode.
