116 Application macrosTorque control macroThis macro provides parameter settings for applications that require torque control ofthe motor. Control can also be switched to speed control using a digital input. Toenable the macro, set the value of parameter 9902 APPLIC MACRO to 8 (TORQUECTRL).For the parameter default values, see section Default values with different macros onpage 180. If you use other than the default connections presented below, see sectionI/O terminals on page 53.
