I/O Signal Descriptions

Current Setting Procedure

Connector Pin no. Signal name Function

To allow the current in each of the following conditions to flow through the motor, connect a voltmeter across [CP1]+ and

[CP2]- and turn RUN control to set the voltage to the value obtained with the following formula.

CN1 1 CW+ (2-clock) Forward rotation signal input (2-clock)

2 CW– (2-clock) Pulse input at 1 clock

Check pin voltage (V) = Set current x 2

3 CCW+ (2-clock) Backward rotation signal input (2-clock) CW when [1]

Rotating direction input at 1 clock CCW when [0]

The current is factory-set to 1.4 A/phase.

4 CCW– (2-clock)

Setting and Handling Procedure:

5 H.O+ Motor energization OFF when [1]

[1] Before turning power ON, turn the RUN knob fully counterclockwise.

6 H.O–

[2] To supply the motor with the driving rated current, apply a forward or backward rotation signal with a frequency of 10 pps

or more and turn RUN knob slowly to set the calculated voltage.

CN2 1 +5V Max. 30 mA to be supplied

2 +V Drive power source 20 to 40 VDC

Note that the motor starts turning when the signal is applied.

[3] The current value set during auto current down is fixed at about 60% of the rated current.

4 GND Drive power source 0 V

[4] To free the motor shaft, set the H.O pin to [1]. This frees the motor even during rotation.

• Keep the input signal line away from the power source and motor lines.

Orange Violet + orange

• Provide good ventilation if used within a cabinet.

• To install, face the mounting surface on the bottom of the main unit down and press it tightly up against metal.

Adjustment of reflector type sensors

The sensor shall be capable of detecting black glass epoxy PWBs with no gloss (no resist) and glass epoxy PWBs with green

resist on bottom surfaces and with no resist on R surfaces.

1. Turn the sensitivity adjustment knob of the sensor to the MIN position.

2. Place a black glass epoxy PWB with no gloss (no resist) on the transport rails above the sensor.

3. Slowly turn the sensitivity adjustment knob of the sensor clockwise from the MIN position and stop turning it when the

indicator lamp lights up.

This adjustment ensures that the sensor detects PWBs of various colors and does not sense any object including the safety

cover other than PWBs.

[1] For the adjustment, use as the workpiece a glass epoxy PWB with green resist on the F surface and with no resist on

R surface.

[2] Place the mode selector switch in the SET position. (If the switch is placed back in the RUN position at this time, a

change of sensitivity setting will not be valid.)

Place the mode selector switch in the

RUN position. This completes the

sensitivity setting.

Change the workpiece position and setting

distance and press the tuning button again.

*If the sensor is to be retuned, keep the

mode selector switch in the SET position

and press the tuning button once again.

The digital display shows "1" again, allowing

you to perform steps from [2] to [4].

Note 1: The same sensitivity setting can be made even if the workpiece conditions are exchanged between steps [3] and

[4].
