2) Controller needs DC24V power supply when using external input and output.
Chapter 11 Common faults and solutions
11.1 Controller fault
11.1.1 Controller can’t enter control interface
Maybe the temperature of screen is too low. To turn on the controller and heat it, then
turn on it again.
There is something wrong with hardware or hardware connection wire, or temperature of
hardware is too low.
Maybe the controller has problem. Please ask help for our after-sale department.
11.1.2 Button fault
Maybe button is damaged, enter Diagn (diagnosis), keyboard
Maybe button shakes, enter Diagn (diagnosis), keyboard
Turn off the controller and turn on it again. If there are still problems, the controller is
damaged. Please ask help for our after-sale department.
11.2 Operation fault
11.2.1 No movement in manual mode
There may be limit in this direction, or press emergent button.
Electrical gear numerator is 0 or denominator is 0.
Servo driver or step driver alarm.
Signal wire connection between controller and driver is improper.
11.2.2 Running distance error
Electrical gear ratio is improper. Change servo driver’s electrical gear or controller’s
electrical gear.
The numbers of gear teeth or modules are improper. Rack’s pitch is improper. Connection
of two racks is improper.
Speed is over 8m/min (1 micrometer per equivalent).
Motor lock-rotor or miss-step (resistance is too big, or worse motor, or motor’s power is
too small).
11.2.3 Improper running speed
Ascending and descending curve parameter is improper (limiting speed should be bigger
than top running speed, but should be below 8m/min; ascending and descending time is
too long or too short, at most 5s).
Speed parameters are improper.
11.3 Program fault
11.3.1 Code and format problem
Program can be made by CAM and saved in the controller. Different CAMs and
postprocessors make different program codes. It’s possible that wrong grammar and code
can’t run. It’s better to revise codes in the computer.
The controller can recognize coordinate in metric system, unit is mm, there are three digits
after the decimal point.
