Direction Input, Shutdown Input | Parker Hannifin 88-020292-01 A

The input is optically isolated. You can drive the input differentially, or from a single-ended source.

Step input specifications are:

Input Current:	6.5 mA minimum
	15 mA	maximum
Input Voltage:	3.5V	minimum	(min. required for on or high signal)
	5.2V	maximum*
Step Pulse:	200 nanosecond minimum pulse width
	200 nanosecond minimum off time
	2 MHz	maximum pulse rate
Optically Isolated:	Yes

*As a custom product, Compumotor can modify drive for higher input voltage

DIRECTION INPUT

While a positive voltage is applied to DIRECTION+ with respect to DIREC- TION–, the drive will commutate the motor in the clockwise (positive) direction as it receives step pulses on its step input.

While zero voltage (or a negative voltage) is applied to DIRECTION+ with respect to DIRECTION–, the drive will commutate the motor in the coun- terclockwise (negative) direction as it receives step pulses.

The input is optically isolated. You can drive the input differentially, or from a single-ended source.

Direction input specifications are:

Input Current:	6.5 mA minimum
	15 mA	maximum
Input Voltage:	3.5V	minimum	(min. required for on or high signal)
	5.2V	maximum*
Optically Isolated:	Yes
Direction Change:	Direction input may change polarity coincident with
	first step pulse.

SHUTDOWN INPUT

You can use the shutdown input to shutdown, or disable, the E-AC Drive. To activate shutdown, apply a positive voltage to SHUTDOWN+ with respect to SHUTDOWN– when the motor is not moving. During shutdown, the drive turns off current to the motor. The current stays off as long as the voltage is maintained on the shutdown input.

When you remove the voltage on the input, shutdown ends. The drive restores current to the motor, in the same phase relationship that existed before shutdown was invoked.

The shutdown input may also be differentially driven. Specifications are:

Input Current:	2.5 mA minimum
	30 mA	maximum
Input Voltage:	3.5V	minimum	(min. required for on or high signal)
	13V	maximum
	5V	maximum reverse voltage
Active Level:	While voltage is applied, current to motor is shut down.
	When voltage is removed, normal operations resume.
Time:	250 nanosecond minimum width
Optically Isolated:	Yes
