How to fix if the chip conveyor stop moving?

The following steps can guide you step by step to determine where the problem is:

Step 1 Check voltage.

Please refer to the table of main voltages and frequencies of your country  or territory :

https://en.wikipedia.org/wiki/Mains_electricity_by_country

Step 2 Check if the power cable connection according to the following pictures.

• 220V as motor applicable voltage

Note: The connection method of the three-phase six-wire motor power line in low voltage (Low Volt) mode is "△ connection", that is, U1 and W2 are connected together, V1 and U2 are connected together, and W1 and V2 are connected together. It is easy to cause overload.

• 380V as motor applicable voltage

Note: The connection method of the three-phase six-wire motor power line in high voltage mode is "star (Y) connection", that is, the three-phase winding head ends U1, V1, W1 are separated, and the tail ends W2, U2 and V2 are connected together to form a common point O. Please confirm whether the wiring is as shown in the figure. If it is connected in a △ shape by mistake, each phase winding will be subjected to a voltage of 380V, causing the stator current to increase and burn the winding.

Step 3 Check power supply unit

Structure description: Thermo Relay (Th-Ry) is used to set the current value to protect the motor. It has an overload protection function to prevent the damage of the motor caused by surge current when the power distribution system is restored after a power outage or when the voltage is unstable. Once the current passing through is greater than the set value, the contact will be tripped and the current will be interrupted to protect the machine device.

Inspection method: Please refer to the figure on the next page to confirm whether the red warning light of the thermal relay in the power supply device is on and the reset button is tripped and popped up. If so, it means that the power supply is overloaded.

Note: The brightness of this red warning light is weak and may not be very obvious due to the influence of the lighting environment on site. You must observe carefully. Please also confirm whether there is a "click" sound when the return button is reset.

Suggested solution =>

Method 1. Reset: Open the power supply unit box, check whether the reset button is pressed, turn off the red warning light, restart the electromagnetic switch, and observe whether the motor resumes operation and the track resumes operation.

Method 2. If the startup problem is not improved after resetting, please check the trip current value indicated by the pointer of the "current adjustment button" to see if it is set within 1~1.25 times the corresponding maximum rated current value (1.2A in the figure) at the specified voltage on the motor nameplate (the red circle on the right figure, the maximum rated current for 220V voltage should be 1.2A). If not, please reset it as suggested and follow method 1 again.

If the problem persists after following the instructions in Method 1 and Method 2, please continue to check in Step 2.

Step 4 Check if belt stops rotating

Step 5 Check if torque limiter overloading and slipped.
