[149] Torque %
lim 4-20mA
Analog output at 0 torque is 12 mA.
Motoring torque increases the output
current to maximum torque limit 20 mA (set
in
parameter 4-16 Torque Limit Motor Mode
).
Generating torque decreases the output to
torque limit in generator mode (set in
parameter 4-17 Torque Limit Generator Mode
)
Example:
Parameter 4-16 Torque Limit Motor
Mode
= 200% and
parameter 4-17 Torque
Limit Generator Mode
= 200%. 20 mA =
200% motoring and 4 mA = 200%

Scale for the minimum output (0 mA or 4 mA)
of the analog signal at terminal 42.

range of the variable selected in

%

[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 required output current at a value 0–100% of
the full-scale output, program the percentage
value in the parameter, that is 50% = 20 mA. If a
current 4–20 mA is required at maximum output
(100%), calculate the percentage value as follows:
20 mA/desired maximum current x 100 %
i . e . 10 mA : 20
10 x 100 = 200 %

is preset to this level if a fieldbus timeout
occurs.
