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
.
