Motor constraint detection output
This pin output is on when the motor is turning and off
when the constraint protection circuit operates.
Constraint protection circuit operating time setting
Insert a capacitor between this pin and ground.
This pin must be connected to ground if the constraint
protection circuit is not used.
PWM pulse input
A low-level input specifies the output drive state, and a
high-level or open input specifies the output off state.
When this pin is used for control, the TOC pin voltage
must be set to a control amplifier input that results in a
100% duty.
Forward/reverse input
Start/Stop input
A low-level input sets the IC to start mode, and a high-
level input sets it to stop mode.
