Function:
An output value set from Network process
data. The output will work independently of
internal functions in the frequency converter.
H-74 Warning Reference Low defines the
behaviour of the analog output in case of bus
time-out.
H-74 Warning Reference Low defines the
behaviour of the analog output in case of bus
time-out.
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.

0 Hz = 0 mA, F-03 Max Output Frequency 1 =
20 mA.
Function:
[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.
Function:
[0 - Scale the maximum output of the selected
200 %] 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:
