Pin function
Frequency characteristics pin.
Connecting a capacitor between
this pin and ground serves to
prevent closed-loop oscillation in
the current control circuitry.
Connecting a capacitor between
this pin and ground activates the
coil output saturation prevention
function. In this condition, the VS
pin is controlled for motor voltage
control.
By adjusting the external capacitor,
torque ripple compensation can be
varied.
PG amplifier output pin.
PG amplifier peak hold capacitor
connection pin.
