Torque Control Macro - ABB ACS850 Manual

96 Application macros

Torque control macro

This macro is used in applications in which torque control of the motor is required.
Torque reference is given through analog input AI2, typically as a current signal in the
range of 0...20 mA (corresponding to 0...100% of rated motor torque).
The start/stop signal is connected to digital input DI1, direction signal to DI2. Through
DI3, it is possible to select speed control instead of torque control.
A constant speed (300 rpm) can be activated through DI4.
