Tab. 8-14: NY4120 drive output characteristics
The following motor types can be connected to the NY4120.
PWM Brushless DC servo motor control (BLDC)
BLDC motors have a trapezoidal stator winding distribution which is designed
for use on a square wave or block commutation inverter supply voltage,
controlled by Hall sensors.
If the Hall sensors are connected to the Dig5VIn inputs, you
cannot use the digital encoders (EnDat2.x, Rexroth MSM or
Hiperface) at the same time, because the Hall sensors use the
same I/O lines as these digital encoders.
PWM Brushless AC servo motor control (BLAC)
BLAC motors have a sinusoidal stator winding distribution which is designed
for use on a sinusoidal or PWM inverter supply voltage. In software, the
alignment between motor coils and magnets is done using for example a
wake-and-shake procedure.
PWM Brushed DC servo motor control (DC)
PWM Stepper motor control
Two phase stepper motors with a sinusoidal current of 7 A rms can be used.
