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.
