Control loop frequency characteristics correction
Insert a capacitor between this pin and ground.
Sets the operating time constant for the constraint
protection circuit.
Hall sensor FG output (This is an open-collector output.)
Motor constraint state detection (This is an open-collector
output.)
This pin outputs a high level if the motor is mechanically
constrained, and it outputs a low level when the motor is
turning.
PWM pulse input
When low, the outputs are turned on, and when high or
open, the outputs are turned off. When these pins are
used for control, connect the EI– pin to ground and the
EI+ pin to the TOC pin.
