1. With check pin TP9 as GND, observe TP1 with an oscilloscope.
Reference clock frequency: 10 msec. ±0.5 msec.
Turn variable resistor VR1 as necessary so that the TP1 signal becomes 10 msec. ±0.5 msec. as shown below.
2. Flip only SW2 of SW1 to 5 of the DIP switch to ON.
Directly concerned with the off delay time of the PWB detection sensor, it affects transport operation for PWBs with slits.
1. PWB transport error

1. Before starting the adjustment procedure, make sure that the DC power source output voltage has been properly adjusted.
Drive current: 1.4 A ±0.005 A/phase
2. Turn the transport stepping motor and measure the voltage across [CP1]+ and [CP2]- on the five-phase stepper driver
with a digital voltmeter.
3. Slowly turn the RUN variable resistor so that the voltage across [CP1]+ and [CP2]- becomes 2.8 V ±0.01 V.
4. Flip the DIP switch keys as follows.
Directly concerned with the rotating torque of the transport stepping motor (centering buffer).
1. Stepping motor out of correct timing, resulting in a transport error.
2. Stepping motor temperature running abnormally high

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.
