Note on brake chopper operation according to cUL/CSA
Brake chopper operation according to cUL/CSA is ensured if the running time t
on
is not
higher than 30% compared to the cycle time t
z
.
The condition is fulfilled if the continuous braking power P
d
is not higher than 30%
compared to the peak braking power P*
