The maximum current allowable by the motor is normaly given by the constructor.

About the second point: do you have try to reset the inerrupt flag? In this case the Z_R interrupt flag.

Anyway I don't understand why the code remains stalled inside that ISR. It is possible that the sensor start to oscillate and give many times a edge transition?

If the sensor give only one edge and the interrupt flag is reset during the ISR there is no reason for re entering in the ISR.

It is better to understand well what's happen.

Hi Gigi,

thanks for your help. We solved the problem with a fix duty cycle and small modifications in the mechanics.

For me is the problem in the Z interrupt a bug of the controller. The sensors are not oscillating. Maybe is this a new theme in the forum.

Thank you so much for your help.
