1.What should I do if there is a problem with the electronic control?
The problem with electronic control is broken down into four small parts:
a. The inverter has an overload phenomenon.
b, the power supply phase loss phenomenon
c, emergency stop switch damage
d, potentiometer damage (speed governor)
Inverter, motor overload reasons and treatment methods
When the inverter display shows E.OL1 and E.OL2;
When the display shows these two numbers, it can be judged immediately because the inverter has appeared.
Loading phenomenon,
Cause of failure / treatment
1. The voltage is unstable, which causes the inverter to not work properly. Treatment method: lower the motor speed without using heavy iron
2. The power cord is too thin or too long as standard. Solution: Replace the standard power cord
3. The hardness of the ground is high or low. Treatment method: lower the motor speed without using heavy iron
2.The power supply phase loss problem Fault phenomenon: Err1 fault display appears on the inverter display
Cause of failure / treatment method:
1. The power cable is damaged. Handling method: Replace the normal power cable. 2. The electrical wiring box of the site is open, the plug, socket, and the inverter cable are disconnected or the contact is poor. Handling method: Check if there is any problem at each wiring. And fix it.
3.The emergency stop switch is damaged.
The machine can not be stopped, the switch can not be used normally, the mechanical life of the switch button is more than 3 million times, and the continuous luminous life of the illuminated button is more than 100,000 hours. However, due to the poor working environment of the floor industry, the improper operation of the workers leads to damage treatment: purchase of normally closed double Contact emergency stop switch and replace.
4.The potentiometer is damaged (speed governor) Fault phenomenon: the machine can not speed or rotate a few turns of the speed control button to adjust the speed
Cause of failure / treatment
1. The potentiometer cap is loose. Treatment: Lock the potentiometer cap
2. Potentiometer damage Treatment method: Replace the potentiometer with normal function
