Peak Power when Decelerating The peak power when decelerating is independent of the supply unit used
and the mains voltage. But the peak power is reduced as of a cable length of
approx. 80 m, due to the voltage limitation taking effect in KSM/KMS.
The critical case is when all motors decelerate at the same time with peak
torque out of maximum speed (e.g., in the case of E‑Stop).
