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 9902 APPLIC MACRO to 8 (TORQUE
CTRL).
For the parameter default values, see section Default values with different macros on
page 180. If you use other than the default connections presented below, see section
I/O terminals on page 53.
