Parameter Descriptions
6-70 Terminal X45/1 Output
Option: Function:
[135] Torque% The torque setting is related to the motor
nom 4-20 torque setting.
mA
[136] Power 4-20 Taken from 1-20 Motor Power [kW]
mA
[137] Speed 4-20 Taken from 3-03 Maximum Reference. 20 mA
mA = Value in 3-03 Maximum Reference.
[138] Torque 4-20 Torque reference related to 160% torque.
mA
[139] Bus ctrl. An output value set from fieldbus process
0-20 mA data. The output will work independently of
internal functions in the frequency converter.
[140] Bus ctrl. An output value set from fieldbus process
4-20 mA data. The output will work independently of
internal functions in the frequency converter.
[141] Bus ctrl. 4-54 Warning Reference Low defines the
0-20 mA, behaviour of the analog output in case of
timeout bus time-out.
[142] Bus ctrl. 4-54 Warning Reference Low defines the
4-20 mA, behaviour of the analog output in case of
timeout bus time-out.
[150] Max Out In relation to 4-19 Max Output Frequency.

6-71 Terminal X45/1 Output Min Scale
Range: Function:
0.00% [0.00 - Scale the minimum output of the selected
*
200.00%] 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, then
programme 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 - Scale the maximum output of the selected
*
200.00%] 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, 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 (example where
desired max. output is 10 mA):
