Parameter Descriptions
6-50 Terminal 42 Output
Option:
Function:
[142] Bus ctrl
Par. 4-54 Warning Reference Low defines the
4-20mA
behaviour of the analog output in case of bus
t.o.
time-out.
[149] Torque %
Analogue output at zero torque = 12 mA.
lim
Motoric torque will increase the output current
4-20mA
to max torque limit 20 mA (set in
par. 4-16 Torque Limit Motor Mode).
Generative torque will decrease the output to
torque limit Generator Mode (set in
par. 4-17 Torque Limit Generator Mode)
Ex: par. 4-16 Torque Limit Motor Mode: 200% and
par. 4-17 Torque Limit Generator Mode: 200%. 20
mA = 200% Motoric and 4 mA = 200% Genera-
toric.

Set the value to be the percentage of the
full range of the variable selected in
par. 6-50 Terminal 42 Output.
6-52 Terminal 42 Output Max Scale
Range:
Function:

[0.00 -
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, programme 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:
