4.5 FC Drive Control Profile

4.5.1 Control Word According to FC Profile
(CTW)
To select Danfoss FC protocol in the control word, set
parameter 8-10 Control Word Profile to [0] FC profile. Use the
control word to send commands from a master (PLC or PC)
to a slave (frequency converter).

Explanation of the control bits
Bits 00/01, reference value
Use bits 00 and 01 to select between the 4 reference
values, which are pre-programmed in parameter 3-10 Preset
Reference according to Table 4.12.
NOTICE
In parameter 8-56 Preset Reference Select, a selection is
made to define how bit 00/01 gates with the
corresponding function on the digital inputs.

Bit 02, DC brake
Bit 02 = 0 leads to DC braking and stop. Braking current
and duration are set in parameter 2-01 DC Brake Current
and parameter 2-02 DC Braking Time.
Bit 02 = 1 leads to ramping.

PROFINET
Bit 03, coasting
Bit 03 = 0 causes the frequency converter immediately to
coast the motor to a standstill.
Bit 03 = 1 enables the frequency converter to start the
motor if the other starting conditions have been fulfilled.
NOTICE
In parameter 8-50 Coasting Select, a selection is made to
define how bit 03 gates with the corresponding function
on a digital input.
Bit 04, quick stop
Bit 04 = 0 quick stops the frequency converter and ramps
the motor speed down to stop via parameter 3-81 Quick
Stop Ramp Time.
Bit 04 = 1 makes the frequency converter ramp the motor
speed down to stop via parameter 3-42 Ramp 1 Ramp
Down Time or parameter 3-52 Ramp 2 Ramp Down Time.
Bit 05, hold output frequency
Bit 05 = 0 freezes the present output frequency (in Hz).
The frozen output frequency can only be changed with the
digital inputs (parameter 5-10 Terminal 18 Digital Input to
parameter 5-15 Terminal 33 Digital Input) programmed to
[21] Speed up and [22] Speed down.
Bit 05 = 1 uses ramp.
Bit 06, ramp stop/start
Bit 06 = 0 stops the frequency converter and the motor
speed ramps down to stop via the selected ramp-down
parameter.
Bit 06 = 1 allows the frequency converter to start the
motor if the other starting conditions have been fulfilled.
NOTICE
In parameter 8-53 Start Select, define how bit 06 ramp
stop/start gates with the corresponding function on a
digital input.
Bit 07, reset
Bit 07 = 0 does not cause a reset.
Bit 07 = 1 resets a trip. Reset is activated on the signal's
leading edge, that is, when changing from logic 0 to logic
1.
Bit 08, jog
Bit 08 = 0, no function.
Bit 08 = 1, parameter 3-19 Jog Speed [RPM] determines the
output frequency.
Bit 09, selection of ramp 1/2
Bit 09 = 0, ramp 1 is active (parameter 3-40 Ramp 1 Type to
parameter 3-47 Ramp 1 S-ramp Ratio at Decel. Start).
Bit 09 = 1, ramp 2 is active (parameter 3-50 Ramp 2 Type to
parameter 3-57 Ramp 2 S-ramp Ratio at Decel. Start).
