Setting Peak and Continuous Torque Limits
TK and TL Commands:
The peak and continuous torque limits can be set through the TK and TL commands respectively. The controller will
command the torque signal (TT) up to the value specified by TK for a maximum of one second, as shown in Figure
A4.2. It will then limit the torque to the value specified by TL. The more time the controller commands the torque
below TL, the longer it will command it to TK when necessary. The DMC code example below exhibits the behavior
of TT being limited by TL and TK, as shown in Figure A4.2.
