H-74 Warning Reference Low defines the
behaviour of the analog output in case of bus

H-74 Warning Reference Low defines the
behaviour of the analog output in case of bus

[149] Torque %
lim 4-20mA
Analog output at zero torque = 12 mA.
Motoric torque will increase the output
current to max torque limit 20 mA (set in
F-40 Torque Limiter (Driving)).
Generative torque will decrease the output to
torque limit Generator Mode (set in
F-41 Torque Limiter (Braking))
Ex: F-40 Torque Limiter (Driving): 200% and
F-41 Torque Limiter (Braking): 200%. 20 mA =
200% Motoric and 4 mA = 200% Generatoric.

AN-51 Terminal 42 Output Min Scale
Range: Function:
0 % * [0 - 200
%]
Scale for the minimum output (0 or 4 mA) of
the analog signal at terminal 42.
Set the value to be the percentage of the full
range of the variable selected in
AN-50 Terminal 42 Output.
AN-52 Terminal 42 Output Max Scale
Range: Function:
100
% *
[0 -
200 %]
Scale the maximum output of the selected
analog signal at terminal 42. Set the value to
the maximum value of the current signal output.
Scale the output to give a current lower than 20
mA at full scale; or 20 mA at an output below
100% of the maximum signal value. If 20 mA is
the desired output current at a value between 0
- 100% of the full-scale output, program the
percentage value in the parameter, i.e. 50% = 20
mA. If a current between 4 and 20 mA is desired
at maximum output (100%), calculate the
percentage value as follows:
