Error Timing of detection
Punch motor
Punch shaft home position sensor
Punch shaft rotational direction
sensor
The turning OFF of the punch shaft home position sensor (S35)
is not detected in the specified time when the punch motor
(M15) is rotated.
The turning ON of the punch shaft home position sensor (S35)
is not detected in the specified time when the punch motor
(M15) is rotated.
The punch shaft home position sensor (S35) and the punch
shaft rotational direction sensor (S34) do not specify the home
position or the rotational direction correspondingly during
initialization, or initialization is not finished at a turning-ON point
for the punch shaft home position sensor (S35).
Probable cause Checking and measures
Punch motor (M15) abnormality Check if the electrical continuity of the coil is normal. If
electricity is not conducted, replace the motor.
Punch shaft home position sensor
(S36) abnormality
Measure the voltage on pin CN3.3 on the hole punch control
PC board (HP). Then check that the measured voltage is 1V or
lower when not shielded and within the range of 5V5% when
shielded. If the voltage does not fall within the range mentioned,
replace the sensor.
Punch shaft rotational direction
sensor (S35) abnormality
Measure the voltage on pin CN3.9 on the hole punch control
PC board (HP). Then check that the measured voltage is 1V or
lower when not shielded and within the range of 5V5% when
shielded. If the voltage does not fall within the range mentioned,
replace the sensor.
