Brake control (short braking operation)
Low: 0 V to 1.0 V
High: 2.0 V to V
Goes high when left open.
High or open for brake mode operation.
The hysteresis is about 0.22 V.
Switches the speed discriminator VCO divisor count.
Low: 0 V to 1.0 V
High: 2.0 V to V
Goes high when left open.
The hysteresis is about 0.22 V.
The speed discriminator count switching.
Low: 0 V to 1.0 V
High: 2.0 V to V
Goes high when left open.
The hysteresis is about 0.22 V.
Speed lock detection output
This is an open collector output.
Goes low when the motor speed is within the speed lock
range (±6.25%).
