What are the common electrical faults and solutions for manual servo presses?
Common electrical faults and solutions for manual servo presses are as follows:
1, motor failure
Failure phenomenon: motor does not turn, abnormal speed or abnormal noise.
Possible causes: power supply failure, motor winding short circuit or disconnection, motor overload, drive failure.
Solution: check whether the power supply is normal, including whether the voltage is stable, whether the line is well connected; use a multimeter and other tools to detect the resistance of the motor winding, to determine whether there is a short circuit or circuit breakage, if there is a need to replace the motor; check the working load of the press, to avoid overloading the operation; check the parameters of the drive is set correctly, as well as whether the drive has a fault alarm, if necessary, contact professionals! If necessary, contact professional personnel to repair or replace the drive.
2、Sensor failure
Failure phenomenon: inaccurate pressure or position sensor feedback, resulting in unstable pressure control or inaccurate position positioning.
Possible causes: sensor damage, improper sensor installation position, sensor line failure.
Solution: Check whether the sensor has obvious signs of damage, such as shell cracks, loose pins, etc., if damaged, replace the sensor; re-adjust the sensor's mounting position to ensure that it is firmly installed and can accurately measure the pressure or position; check whether the sensor's connecting wires are disconnected, short-circuited, or poor contact, repair or replacement of the line.
3、Control system failure
Failure phenomenon: no response to the operating panel, abnormal program operation, control logic error.
Possible causes: control system power failure, controller hardware failure, program error or loss.
Solution: Check the power supply of the control system to ensure that the voltage is stable and meets the requirements; check whether the controller hardware connection is normal, such as loose or damaged, repair or replace it in time; if it is a program problem, try to restart the device to see whether it can return to normal. If the problem still exists, you may need to re-download or update the program, or contact the technical support staff of the equipment manufacturer for remote assistance or on-site repair.
4, line failure
Failure phenomenon: part of the equipment function fails, electrical components without power or signal transmission abnormalities.
Possible causes: aging wires, broken, short-circuit, loose terminals.
Solution: carefully check the electrical lines of the equipment, found that the aging or damaged wires should be replaced in a timely manner; find the short-circuit point, eliminate short-circuit faults; fasten all the terminals to ensure that the connection is reliable. When checking the line, you can use insulation resistance tester and other tools to detect the insulation properties of the line and through the situation.
5、Power failure
Failure phenomenon: the equipment can not start normally, or in the process of operation suddenly stop.
Possible causes: poor contact with the power socket, power cord damage, blown fuse, power module failure.
Solution: Check whether the power socket is energized, try to replace a socket; check whether the power cord is broken or fractured, if so, replace the power cord; check whether the fuse is blown, if blown, replace the fuse with the same specification; if it is a power module failure, you need a professional to carry out repairs or replacement of the power module.
When performing electrical troubleshooting and repair, be sure to cut off the power supply before repairing. If you are not familiar with the electrical knowledge and maintenance operation, it is recommended that you contact a professional technician for maintenance in time to avoid more serious damage.
