mA
Par. 3-00 [-Max-Max] -100% = 4 mA; 0% = 12

[133] Motor cur.
4-20 mA
Value is taken from 16-37 Inv. Max. Current .
Inverter max. current (160% current) is equal
to 20 mA.
Example: Inverter norm current (15 hp [11
kW]) = 24 A. 160% = 38.4 A. Motor norm
current = 22 A Readout 11.46 mA.

If the norm motor current is equal to 20 mA,
the output setting of 6-52 Terminal 42 Output

The torque setting is related to setting in
4-16 Torque Limit Motor Mode .
[135] Torque %
nom 4-20
mA
The torque setting is related to the motor
torque setting.
[136] Power 4-20

[138] Torque 4-20
mA
Torque reference related to 160% torque.
[139] Bus ctrl. 0-20
mA
An output value set from the serial communi-
cation bus process data. The output will work
independently of internal functions in the
adjustable frequency drive.
[140] Bus ctrl. 4-20
mA
An output value set from the serial communi-
cation bus process data. The output will work

Option: Function:
independently of internal functions in the
adjustable frequency drive.

mA, timeout
4-54 Warning Reference Low defines the
behavior of the analog output in case of bus
timeout.
[142] Bus ctrl. 4-20
mA, timeout
4-54 Warning Reference Low defines the
behavior of the analog output in case of bus
timeout.

6-71 Terminal X45/1 Output Min Scale
Range: Function:
0.00%
* [0.00
‒
200.00%]
Scale the minimum output of the selected
analog signal at terminal X45/1, as a
percentage of the maximum signal value,
e.g., if 0 mA (or 0 Hz) is desired at 25% of
the maximum output value, program 25%.
Scaling values up to 100% can never be
higher than the corresponding setting in
6-72 Terminal X45/1 Max. Scale .
6-72 Terminal X45/1 Output Max Scale
Range: Function:
100%
*
[0.00
‒
200.00%]
Scale the maximum output of the selected
analog signal at terminal X45/1. 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 (example where desired max. output
is 10 mA):
