Programming
Ramp 2, is selected if a shift between ramp 1 (parameters
207-208) and ramp 2 (parameters 209-210) is required.
Logic "0" leads to ramp 1 and logic "1" leads to ramp 2.
Start-ref bit 1,2 and 3, makes it possible to select which REF
RESET (1-7) is to be used. The REF PRESET (1-7) are set in
parameters 241 to 247.

If at least one of the 3 digital inputs is activated the FCM
has start signal. The 7 possible input combinations will
then decide which preset speed is to be used.
If only 1 or 2 digital inputs are used respectively 1 or 3
speeds can be chosen after above shown principle.
If 2 set-ups are used up to 14 preset speeds can be chosen
by means of 4 digital inputs. The P241 and P242 settings
will be mirrored into P215 and P216.
Ex.
Digital inputs 2,3 and 4: P332 [choice 35 selected], P333
[choice 36 selected] and P334 [choice 37 selected]
Input combination on the digital inputs 2,3 and 4: "010".
This means REF PRESET 2 will be the preset speed.
Scaling of the input signal is effected in parameters 338
and 339.
336 Terminal 1, min. scaling
Value:
0.0-20.0 mA
0.0 mA
Function:
This parameter determines the value of the reference
signal that is to correspond to the minimum reference
value set in parameter 204.
If the Time-out function of parameter 317 is to be used,
the setting must be > 2 mA.

Description of choice:
Set the desired current value.
337
Value:
START REF BIT
321
Function:
000
This parameter sets the value of the reference signal that is
001
to correspond to the maximum reference value set in
010
parameter 205.
011
Description of choice:
100
Set the desired current value.

110
Value:
111
Function:
This parameter is used for setting the signal value that is
to correspond to the minimum reference or the minimum
feedback, parameter 204 Minimum reference, Ref
Minimum feedback, FB
Description of choice:
Set the required voltage value. For reasons of accuracy,
compensation should be made for voltage loss in long
signal cables. If the Time out function is to be used
(parameter 317 Time out and 318 Function after time out),
the value set must be higher than 1 Volt.
339
Value:
Function:
This parameter is used for setting the signal value that is
to correspond to the maximum reference value or
[0-200]
maximum feedback, parameter 205 Maximum reference,
[0]

Description of choice:
Set the required voltage value. For reasons of accuracy,
compensation should be made for voltage losses in long
signal cables.
