High current in CCW

7 years 9 months ago #29527703 by tfiorenzani
Hi, I have an SDC2130 wich shows a strange behaviour. I have measured the PWM on the motor\'s pole and it seems there is a peack of about 50V (the Vin is 24V) at each wave.

The problem is that if we change direction, the board goes into protection mode, because there is a peack of current. I have attached a file with all the pictures.

I have tried different motors and also to change the output port, but nothing changes.

It does not happen every time, but often.

I have updated to the new firmware, but with no results.

Please, help

Thanks, Tiziano
