Torque Control Macro - ABB ACS355 series User Manual

116 Application macros

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
CTRL).
For the parameter default values, see section
page 180. If you use other than the default connections presented below, see section
I/O terminals on page 53.
