v grooving machine for sheet metal

When setting parameters in reading groups read screen, press the function key read F6, read the corresponding process parameters, in a total of 10 sets of data read parameters, when the machine which has been slotted to save all parameters in the boot screen, press By reading the parameters corresponding to the next column to read parameter function key to enter the operating mode.

Common Faults and exclusion

Servo Fault information table

ALE 01: Overcurrent Need DI: ARST clear, UVW cable or motor failure
ALE 02: OvervoltageNeed DI: ARST cleared, the peripheral voltage is too large
ALE 03: Low VoltageReply voltage automatically cleared
ALE 06: OverloadNeed DI: ARST clear, UVW wire transfer or electrical or mechanical malfunction bet
ALE 11: Encoder alarm Need DI: ARST Clear, encoder cable or motor failure

Commen alarm



Position servo loop system generates an error. The situation of generating an error would be:

Controller to send commands too fast, with the servo motor can not respond to;

2.The controller does not receive feedback signal. That servo motor may alarm;


1.Please check the program, F value is set too large;

2.Resolution set whether error;

3.Check the machine or motor is blocked or not. Check the wiring.



Axial tool than hardware range of travel restrictions.


Use manually move the axis to the working stroke within.



The controller is currently in an emergency stop state.


After removing the condition, turn on the emergency stop button, press the RESET button.
