1. Sweeping: Sweeping is generally caused by friction of the stator and rotor due to bearing damage, shaft bending, or improper assembly during maintenance. In the process of overhaul and assembly of the motor, the parts of the motor should be kept clean, and the assembly of the end cover, bearing, etc. should be reasonable and not barbaric construction, otherwise ...

1. The motor cannot rotate after being energized, but there is no abnormal noise, no peculiar smell and smoke. 1. Cause of failure (1) The power supply is not connected (at least two phases are not connected); (2) Fuse blowing (at least two-phase blowing); (3) The overcurrent relay is adjusted too small; (4) Control ...

6. When the motor is unloaded and overloaded, the ammeter pointer is unstable and swings 1. Cause of failure (1) The cage rotor guide bar is welded or broken; (2) Winding rotor fault (one-phase break) or poor contact of brushes and collector ring short-circuit devices. 2. Troubleshooting ...

1. Remove the motor encoder, power on the system, and power on the driver 2. Set the drive password to 510 and the No. 4 parameter to 4 (encoder zeroing mode) 3. Switch the driver to the encoder zero mode CO-press the confirm key to enter the CO-rdy ...

1. Please check the motor power line to confirm whether there is a short circuit in the phase wire of the motor 2. If there is no short circuit in the phase line of the motor, it is determined that the internal power tube problem of the driver is determined

1. Excessive load: Confirm whether the connected load exceeds the rated load capacity of the drive. The load is too large and needs to be reduced appropriately to ensure that the current is within the allowable range. 2. The driving system parameter setting is incorrect: check whether the driver parameter setting is correct. 3、 ...

1. Check whether the joints of each connecting line are loose; 2. Check whether there is a conflict between the serial port and the abort number, and if there is a conflict, the resources should be adjusted to circumvent the conflict. Then check whether there are gaps in the surface layer of the human-machine interface, and if there are gaps, they should be replaced immediately. It also needs to be inspected ...

1. Change the rotational speed by changing the frequency of the mains supply This is a common method of speed adjustment for AC motors. The power supply frequency can be adjusted to the desired speed by adjusting the inverter, transformer, and other equipment. 2. Change the rotational speed by changing the voltage In some special cases ...
