DIR- (DIR)

representing two directions of motor rotation; in double-pulse mode (set by

SW5), this signal is counter-clock (CCW) pulse, effective on each rising edge.

For reliable motion response, direction signal should be sent to driver 5us

before the first pulse in the reverse motion direction.

ENA+ (+5V)

ENA- (ENA)

Enable signal: this signal is used for enabling/disabling the driver. High level for

enabling the driver and low level for disabling the driver. Usually left

unconnected(enabled).

READY+

Output alarm signal positive: READY is a photocouper output from

open-collector circuit, effectively output when driver operate normally,

maximum permitted input voltage 30VDC; maximum output current 20mA,

generally can be serial connected to PLC input terminal.

READY-

Output alarm signal negative.

Remark 1: SW5 ON means CW/CCW (pulse/pulse), OFF means PUL/DIR mode.

Remark 2: Please note motion direction is also related to motor-driver wiring match. Exchanging the

connection of two wires for a coil to the driver will reverse motion direction. (for example, reconnecting

motor A+ to driver A- and motor A- to driver A+ will invert motion direction).
