What are some common control unit failures and solutions for motor motor rotor slot wedges?

What are common control unit failures and solutions for motor motor rotor slot wedge machine?

According to the search results, the following are motor motor rotor slot wedge machine common control unit failure and solution:

1、 go paper force control failure:

Failure phenomenon: insufficient tension in the paper supply process, or the running tension is set too small.

Solution: adjust the tension, increase the maximum braking voltage setting.

2、the paper supply process tension instability:

Failure phenomenon: floating roller swing too large.

Solution: Check whether the zero position of the tension potentiometer is correct, adjust or replace the brake coil or brake friction plate.

3、The floating roller fluctuates up and down when the diameter of the paper roll is large:

Fault phenomenon: floating roll up and down intermittent fluctuations.

Solution: check whether the brake friction plate is badly worn, if necessary, replace the friction plate, and clean the brake friction plate, can be cleaned with gasoline, but must cut off the machine's main power supply to be cooled before production.

4、Splicing paper printing in the process of heavy shadow:

Fault phenomenon: may be the operating panel accelerator clutch air pressure setting is too large.

Solution: lower the air pressure setting; check the tension setting value, if necessary, increase the setting value; check the pulse encoder wiring or replacement.

5、before the splicing action in the small paper roll and the joint between the paper break:

Failure phenomenon: may be the operating screen on the paper splicing braking force setting is too large.

Solution: Reduce the braking force setting; check whether the brake friction plate is too dirty and need to be cleaned; check whether the joint level or paper stone is damaged.

6、after splicing the paper between the connector and the floating rollers appear broken paper:

Fault phenomenon: acceleration pressure is too high.

Solution: Adjust the acceleration pressure appropriately; check whether the acceleration clutch can be disengaged, adjust the gap or clean and replace.

7、the paper cutter does not move during the splicing process or can not cut the old paper roll:

Fault phenomenon: may be a zero-speed signal problem.

Solution: Check the zero-speed proximity switch wiring and sensing gap; check the paper cutter cylinder air tube is off, air leakage or operating screen on the paper splicing braking force setting is too small.

8、electrical failure:

Failure phenomenon: the inverter can not start, motor heating abnormalities, operation failure.

Solution: check the line contact or communication interference and other faults.

Above is the motor motor rotor slot wedge machine control unit may encounter some common failures and their solutions, for different failure phenomena, should take appropriate inspection and maintenance measures to ensure the normal operation of the equipment and production efficiency.
