Code Modbus ID Parameter Application RO/RW
P2.4.6 181 AI1 Signal Invert 1,2,3 RW
This parameter is used to invert the logic of the analog input.
0 No Inversion = no inversion of analog Vin signal takes place. 0V/0(4)mA = min frequency,
10V/20mA = max frequency
1 Inverted = inversion of analog signal takes place. 0V/0(4)mA = max frequency, 10V/20mA = min frequency.

Minimum AI1 signal = maximum set speed.
P2.4.7 178 AI1 Joystick Hyst 3 RW
This parameter is used to set the analog joystick control hysteresis around the 0 speed reference. To ignore
values around the 0 speed reference, set the value greater then 0%, this will cause a +/- dead band around
the low analog reference. With an analog signal at 0+/- this value the reference will stay at 0Hz or min
speed.
