6-71 Terminal X45/1 Min. Scale
Default value:
0%
Setup: All setups
Data type:
Int16
Scale the minimum output of the selected analog signal at terminal X45/1 as a percentage of the maximum signal value. For example,
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%
Setup: All setups
Data type: Int16
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 the
parameter, for example 50% = 20 mA. If a current 4–20 mA is required at maximum output (100%), calculate the percentage value as
follows (example where required maximum output is 10 mA):

Description
Parameter 4-54 Warning Reference Low defines the behavior of
the analog output in case of fieldbus 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 Generator Mode = 200%. 20 mA = 200%
motoring and 4 mA = 200% generating.
0 Hz = 0 mA, parameter 4-19 Max Output Frequency = 20 mA.
