5.6.2.2 Torque control with speed limitation
For torque-controlled operation, a torque setpoint is defined in the drive system. Unlike the Speed
control with torque limitation , this type of control has a deactivated speed controller and torque
limitation.
• The torque setpoint is calculated directly from nTorqueSetValue_a.
• The speed is defined by the process.
• Due to its limitation, the speed-controlled drive can only rotate within a speed range whose
positive speed is limited by nSpeedHighLimit_a and whose negative speed is limited by
nSpeedLowLimit_a.
