Thanks!

Thanks for your quick reply Patrick!

So, for limiting the magnitude of Current spikes, I should use the Torque limiter then, right? And what does "interrupting" PWM mean, setting throttle / motor input Voltage to zero?

Torque limit would be good for limiting current spikes during hard acceleration. The current limiter has just a couple settings, can't really be used as a general purpose current limit - -it's not designed that way. The PWM is shut down for several commutation cycles when it trips.

Thanx!
