one. Bucket magazine failure reason:
1. Cutter motor, feed motor, retract motor
2. There is a problem with the signal detection circuit in which the infeed is in place and the retraction is in place.
3. The spindle is loose, the knife is in place, the signal detection circuit has a problem, or the push knife distance is deviated.
4. Spindle positioning angle is deviated
5. The second reference point of the spindle has a deviation
6. Tool magazine
7. The cutter head count switch is damaged or the cutter head rotation does not stop.
1. Adjust the motor wiring phase sequence
2. Adjust the position of the infeed and retract sensor switch, such as damage replacement
3. Adjust the loose, tight knife position switch and knife cylinder push knife distance
4. Adjust the spindle parameter 3207 (Mitsubishi) parameter 4077 (Fanak) to the appropriate angle

6. Do the tool magazine number return to zero operation PLC switch No. 16 (Mitsubishi), PMC switch K2.0 (Fanako)
7. Adjust the position of the counting switch. If it is damaged, it needs to be replaced. Disk knife library failure reason:
1. The cutter motor and arm motor have the opposite phase sequence
2. Brake disc motor, arm motor brakes are not tight

4. There is a deviation in the position of the arm knives, the buckle is not tight, and there is abnormal noise.
5. The arm is not returned to zero, the tool change can not continue
6. Tool set number confusion solution:
1. Adjust the phase of the cutter motor and arm motor to the correct
2. Adjust the gap between the cutter motor and the arm motor brake pad to about 30 wire with a feeler gauge
3. Adjust the knife sleeve cylinder push knife up and down position sensor switch position to the appropriate
4. Adjust the position of the second reference point, the positioning angle of the spindle, the position of the spindle release knife, and the position adjustment switch of the knife
5. Manually adjust the arm adjustment nut to the home position, and the original light will be illuminated.
6. Refer to the company's delivery operation manual to complete the zero-step operation steps of the disk cutter pocket

Magnetic Light

We diviided the led light according to the using eviiroment. Most of our product is the commercial LED Lighting

Commercial lighting is a term used to describe lighting that is used in commercial spaces, including auto dealerships, distribution centers, churches, factories, offices, and warehouses. Unlike residential lighting, commercial lighting is made to withstand more abuse and has a longer lifespan.

While the focus of residential lighting is often on aesthetics, commercial lighting is task orientated. Commercial lighting systems are designed based on what the application is. For example, in an office-type setting, you may see task lighting, which illuminates specific areas where employees need concentrated light to be able to perform their jobs.
