3-2-20 Height Sensor Voltage Error
1. Connecting connectors
Check the connection between the CPU box board (NFM0CL) connector (CN1), and recover the
error if necessary.
2. Adjusting the volume
Display the “Axis information” screen after “Machine adjust,” and press the [mm] switch of current
position count. Check that “Detection height ∗. ∗ ∗” displayed at the lower right of the screen
matches the value displayed at the volume LED of the height sensor.
If the value is not proper, turn the knob of “ADJUST” to adjust it to the same one. (The value for the
axis information changes.)

3-2-22 CPU Power Supply Fault
PRU Power Supply Fault
1. Checking the voltage of checking pin
CM88S-M/M1, CM88C-D
If following voltage cannot be measured between checking pins of power board at the CPU box,
the board may have a trouble. Make contact with us for changing.
Between GND3 pin and + 24V pin : + 24V
Between GND2 pin and + 12V pin : + 12V
Between GND2 pin and – 12V pin : – 12V
Between GND1 pin and + 5VC pin : + 5V
CM88S-MU
If following voltage cannot be measured between terminals of the power supply for specified
voltage at the CPU box, the board may have trouble.
P100E-24 : + 24V
P50E-12 : + 12V
P15E-12 : + 12V
P100E-5 : + 5V
2. Canceling the tripped circuit protector
Note) Even if the trouble is not confirmed at the cure 1, carry out the cure 2.
If the circuit protector reset switch at the left side of CPU BOX protrudes by a few millimeters, it is
tripped out. To reset, press it with a pen, etc. with a fine point.
If the upper circuit protector is tripped out, the output system of solenoid, etc. may be in trouble. If
the lower one is tripped out, the input system of sensor, etc. may be in trouble. Check which one is
tripped out, then make contact with us.
