I believe many customers have encountered unexplained issues with the alarm of glass irregular edge grinding machines. In fact, these are all small problems. If everyone can self check and identify the problem and solve it, then everyone does not have to wait anxiously for the machine manufacturer's sales representative to come to the door, and production will be smoother. Below, we will introduce the troubleshooting methods for alarm faults

1. AL007 motor over speed alarm, first check if the machinery is stuck and if the speed is over speed

2. AL009 position deviation alarm, as above

3. AL006 overload alarm: Check if the power line UVW is connected correctly; Check the machinery

4. AL011 and AL024; AL028; AL026 encoding signal alarm, first check if the motor parameters match, then check or replace the encoding line, and finally check or replace the motor

5. AL003 (undervoltage) and AL002 (overvoltage) alarms are triggered to detect whether the input power supply voltage is normal. If the external condition is normal, replace the drive

6. AL001 overcurrent alarm, check the wiring status between the motor and driver or whether the conductor body is short circuited, as well as the wiring sequence between the motor and driver, and whether the temperature of the heat sink is abnormal

7. AL004 motor matching abnormal alarm, check if the motor matches the driver, and if not, set the parameters of the driver to correspond to it

8. AL031 motor U, V, W wiring error alarm, motor POWER LINE U, V, W, GND wiring error, please connect the wires according to the color, and lock the red (U), white (V), and black (W) wires on the motor output socket of the drive L in sequence
