) The drive current path of the position sensing device should be connected to the GND independently.

It should be separated especially from the output current path.

If there is a plunge in position sensing device, insert the condenser (0.05~1µF) between + pin and –

pin of each position sensing device.

If there is a plunge in control input, insert the condenser (0.001∼0.1µF) between this pin and the

GND.

) If upper oscillation (5MHz or more) is found, connect the condensers commonly from each coil output

Aside from using a ringing absorbing condenser, consider a different method to connect the
