Problem Cause Solution
Motor does not work at all
1. Motor malfunction
2. Wiring problem
1. Replace motor
2. Check to see if wiring *1 is
malfunctioning or detached.
Current in Motor, but
Does Not Run
1. Mechanical obstruction
2. Incorrect driver setting
1. Remove obstruction
2. Check current and switch
settings.
Motor reaches end limit
but does not stop
1. Incorrect limit sensor position
2. Limit sensor malfunction
1. Check installation position of
sensor
2. Replace sensor
6.2.1 Stepping Motor Driver Problem
6.2.1.1 RUN and STOP adjustment
l There are two variable resistors located below the Driver. There’s a cross-shaped location
where the variable resistor can be adjusted. Use the adjustment rod to turn the arrow at the
cross location, turn in a clockwise direction to increase.
6.2.1.2 Replacement
l First turn off the power then remove the two sets of wires and two DC +24V power supply cables
from the Driver. There’s a screw at the top and bottom of the driver, remove the screws to install the
new Driver. Once replacement is complete, reconnect the wiring and power cables. After
replacement re-adjust the driver using the adjustment method.
6.2.2 Wiring Problem: Refer to the Wiring Diagram

6.3 Conveyor Belt
l Sensor or Conveyor Problem: perform a test manually (the two hidden buttons must be
pressed simultaneously, the setting procedure is as shown in figures below) and depending
on the results, refer to the table below and troubleshoot.

6.3.1 Sensor Problem－Adjustment:
l Sensor 1 & 2 & 4: Place the candidate board on the Sensor to be tested, and use the
adjustment rod to adjust the Sensor’s optimal detection range (When there’s a candidate
board waiting to be tested over the Sensor, the Sensor’s indicator light will glow red. If there
is no candidate board over the Sensor, the indicator light will turn off.)
l Sensor 5 & 6: Lowers the holder mechanism to its lowest position along with the Sensor as
well. Move the Sensor upwards until the indicator light is lit, then move it slowly downwards
again until the indicator light goes off for the correct setting.
l If there is no response from the Sensor, first re-adjust the Sensor sensitivity. If there is still
no response, do not attempt repair, replace with new Sensor. Replacement: If the Sensor is
not working, then the Sensor’s sensitivity should be re-adjusted. If it still does not operate,
replace with a new sensor. Replacement Method: first disconnect the Sensor connector, and
then remove the Sensor. Attach the new Sensor then connect and secure the Sensor’s
connectors. Once replacement is complete, adjust as directed in the adjustment method.
6.3.2 Check Stepping Motor Driver Problem
6.3.2.1 Are the RUN & STOP currents set to 80% and the switch positions as below? If
not, please configure them using the procedure below:
