VREG

11

CSD

Sets the operating time constant for the constraint

protection circuit.

12

FG Hall sensor FG output (This is an open-collector output.)

VREG

Motor constraint state detection (This is an open-collector

output.)

13

RD This pin outputs a high level if the motor is mechanically

constrained, and it outputs a low level when the motor is

turning.

VREG

PWM pulse input

When low, the outputs are turned on, and when high or

14 PWM IN 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.
