6-71 Terminal X45/1 Min. Scale
Default value: 0%
Conversion index: -2
Scale the minimum output of the selected analog signal at terminal X45/1 as a percentage of the maximum signal value. For exam-
ple, if 0 mA (or 0 Hz) is required at 25% of the maximum output value, then program 25%. Scaling values up to 100% can never
exceed the corresponding setting in parameter 6-72 Terminal X45/1 Max. Scale.

6-72 Terminal X45/1 Max. Scale
Default value: 100%
Conversion index: -2
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 required output current at a value between 0–100% of the full-scale output, program the percentage value in

Description
Taken from parameter 3-03 Maximum Reference. 20 mA = value in parameter 3-03 Maximum Refer-
ence.
Torque reference related to 160% torque.
An output value set from fieldbus process data. The output works independently of internal func-
tions in the drive.
An output value set from fieldbus process data. The output works independently of internal func-
tions in the drive.
Parameter 4-54 Warning Reference Low defines the behavior of the analog output in case of field-
bus timeout.
Parameter 4-54 Warning Reference Low defines the behavior of the analog output in case of field-
bus timeout.
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 Genera-
tor Mode = 200%. 20 mA = 200% motoring and 4 mA = 200% generating.
0 Hz = 0 mA, parameter 4-19 Max Output Frequency = 20 mA.
