The measurement of the motor current in the NY4120, NY4125 and NY4140
modules is done in the middle of the passive cycle of the drive output PWM
period. To get an accurate measurement of the motor current, the PWM
frequency and the motor inductance must have minimum values. If the motor
inductance is too low, additional chokes must be added in the motor wiring.
