4.4 Danfoss FC Control Profile

4.4.1 Objects in FC Profile

In FC profile, DSP 402 profile objects (6000h to 6FFFh)
cannot be used. When parameter 8-10 Control Word Profile
is set to [0] FC Profile:
•
Use object 2690h as control word, which is
parameter 16-80 Fieldbus CTW 1.
4 4
•
Use object 2692h as reference, which is
parameter 16-82 Fieldbus REF 1.

Set-up
Table 4.8 Set-up
NOTICE
In parameter 8-56 Preset Reference Select, select how bit
00/01 gates with the corresponding function on the
digital inputs.
Bit 02, DC brake
Bit 02 = 0: Apply DC brake and stop. The braking current
and braking duration are set in parameter 2-01 DC Brake
Current and parameter 2-02 DC Braking Time.
Bit 02 = 1: Perform ramping.
Bit 03, Coasting
Bit 03 = 0: The frequency converter releases the motor
immediately (the output transistors are shut off), so that it
coasts to a standstill.
Bit 03 = 1: Enables the frequency converter to start the
motor, if the other starting conditions are fulfilled.
NOTICE
In parameter 8-50 Coasting Select, select how bit 03 gates
with the corresponding function on a digital input.
Bit 04, Quick stop
Bit 04 = 0: The frequency converter ramps the motor
speed down to a stop using parameter 3-81 Quick Stop
Ramp Time.
Bit 05, Hold output frequency
Bit 05 = 0: Freezes the current output frequency (in Hz).
The frozen output frequency can then be changed only
with 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.
NOTICE
If hold output frequency is active, the frequency
converter can only be stopped by the following:
