Symptom Possible Cause Correction *
Origin detection plate beyond reach of
detection switch.
Inspect and adjust.
Origin detection switch wire is loose or
damaged.
Check connections.
Origin detection switch damaged. Replace.
Interface board is broken. Repair or replace.
50-pin data cable is broken. Replace date line.
Machine moves reverse
direction when homing.
Faulty connection between origin
detection switch and interface board.
Refresh line to determine if wiring is correct.
Origin detection switch damaged. Replace.
Electrical interference causing false
signal that limit switch has been
triggered.
Recalibrate circuit.
Interface board is broken. Repair or replace.
50-pin data cable is broken. Replace data line.
Router head does not
stop after contacting tool
touch-off puck.
Poor connection of “Cutter” signal line
to “cutter” terminal.
Restore proper connection.
Poor connection of spindle with “GND”
terminal on interface board.
Restore proper connection.
Machine will not move
after controller receives
commands.
One axis not moving – may be poor
connection.
Connect a different axis connection to this
terminal to test. If it works, motor driver is
okay.
Check 50-pin cable connection to interface
board. If machine still won’t move, determine
corresponding drive and motor.
All axes not moving. First, check 50-pin cable connection to
interface board. Then check power supply of
motor drivers. Last check mechanical
elements of axis system.
Machine moves to new
position satisfactorily, but
does not return correctly
to original position.
Mechanical elements, such as ball
screws, are loose or misadjusted.
Inspect and correct as needed.
Abnormal operation when
processing.
Program/drawing file is faulty. Review program and reload to system.
Electrical interference. Inspect connections; separate strong and
weak electrical current; separate “GND” of
inverter from the other components.
After controller powers
on, one or more axes
move only one direction.
Improper connection between interface
board and motor drive.
Inspect connections.
Interface board damaged. Replace interface board.
Motor driver damaged. Replace driver.
After controller powers
on, axis motor will not
move.
Pulse line and direction line are
switched.
Rewire pulse and direction lines.
5V common anode end of motor driver
is disconnected.
Check connection.
Motor driver damaged. Replace driver.
No pulse signal output, interface board
chip damaged.
Replace chip.
