How to confirm that the MC110 is able to read a PWM signal


For safety reasons, it is better to do this test without the motor connected or powered.

Power up the controller via user cable, without connecting the motor or the input power. If the input command is higher than the deadband, the MC will start to control (even though there is no motor connected). Then, a noise of 16 kHz will sound due to the PWM switching. If the input command is reduced to below the deadband, the MC and its noise will stop.
