Torque Control Macro; Default I/O Connections - ABB ACS350 User Manual

Torque Control macro

This macro provides parameter settings for applications that require torque control of
the motor. Control can also be switched to speed control using a digital input. To
enable the macro, set the value of parameter
For the parameter default values, see section
on page 142. If you use other than the default connections presented below, see

Speed control: Changes rotation direction.
Torque control: Changes torque direction.
