Group 28 SPEED CONTROL
Speed controller settings such as
• selection of source for speed error
• adjustment of PID-type speed controller variables
• limitation of speed controller output torque
• selection of source for acceleration compensation torque
• forcing an external value to the output of the speed controller (with the balancing
function).
• adjustment of the load sharing in a Master/Follower application run by several
drives (the drooping function).
The speed controller includes an anti-windup function (ie, I-term is frozen during
torque reference limitation).
In torque control mode, the speed controller output is frozen.
