Application Macro: Torque Control

This macro provides parameter settings for applications that require torque control of
the motor. Control can also be switched to speed control. To enable, set the value of
parameter 9902 to 8 (
Connection example:
• Two analog references (AI1, 2)
• Start/stop and direction (DI1, 2)
• Speed/torque control (DI3)
• Constant speed selection (DI4)
• Ramp pair 1/2 selection (DI5)
• Run enable (DI6)
