RELIANCE VZ3000G Ryan Servo Drive UVZC341A

Ryan servo motor common failure

First, the servo motor can not rotate after the power is turned on, but it is no different, and there is no odor and smoke.

1. Cause of the fault

① The power supply is not on (at least two phases are not on);

② Fuse fuse (at least two phase fuse) :

③ The overcurrent relay is too small;

④ The control device is connected incorrectly.

2. Troubleshoot the fault

① Check the power circuit switch, fuse, junction box is broken, repair; ② Check the fuse type, the cause of the fuse break, and replace the fuse:

③ Adjust the setting value of the relay and the motor:

④ Correct the wiring.

Second, the servo motor does not turn after the power is buzzing

1. Cause of the fault

① The rotor winding has a break (-phase break line) or a phase loss of power supply :② the beginning end of the winding lead line is misconnected or the winding is reversed;

③ The power loop contact is loose, and the contact resistance is large:

④ the motor load is too large or the rotor is stuck;

⑤ The power supply voltage is too low;

⑥ Small motor assembly is too tight or bearing oil is too strong;

⑦ The bearing is stuck.

2. Troubleshoot the fault

① Identify the breakpoint and repair it;

② Check the polarity of the winding; Determine whether the end of the winding is correct;

③ Tighten the loose wiring screws, use a multimeter to determine whether the joints are false, and repair them;

④ Reduce the load or detect and eliminate mechanical faults,

⑤ Check whether the specified face connection method is mistakenly connected: whether the voltage drop is too large due to the power wire is too thin, to be corrected, ⑥ reassembly to make it flexible; Replace qualified grease;

⑦ Repair bearings.

Three, servo motor bearing overheating

1. Cause of the fault

① Too much or too little grease:

② Poor oil containing impurities:

(3) Improper combination of bearing and journal or end cap (too loose or too tight);

④ the bearing inner hole is eccentric, and the shaft is rubbed;

⑤ Motor end cover or bearing cover is not installed flat;

The coupling between the motor and the load is not corrected, or the belt is too tight;

⑦ bearing clearance is too large or too small;

⑧ The motor shaft is bent.

2. Troubleshoot the fault

① Add grease according to the regulations (1/3-2/3 of the volume);

② Replace the clean lubricating grease:

③ Too loose can be repaired by binder, too tight should be applied, grinding the inner hole of the journal or end cover to make it suitable; ④ Repair bearing cover to eliminate friction points:

⑤ Reassembly;

⑥ Recalibrate and adjust the belt tension;

⑦ Replace the new bearing;

⑧ Correct motor shaft or replace rotor.

Analysis of common faults in servo motor operation

1. Motor deviation counter overflow error occurs during high-speed rotation.

Countermeasures: Check whether the wiring of the motor power cable and the encoder cable is correct, and whether the cable is damaged.

2. Motor deviation counter overflow error occurs during operation.

Countermeasures: increase the setting value of deviation counter overflow level; Slow down the rotation speed; Extend the acceleration and deceleration time; If the load is too heavy, it is necessary to re-select a motor with a larger capacity or reduce the load, and install a transmission mechanism such as a reducer to improve the load capacity.

3, the servo motor does not run when there is a pulse output, how to deal with?

A. Monitor the current value of the pulse output of the controller and whether the pulse output light blinks, and confirm that the command pulse has been executed and the output pulse has been normal;

b. Check the control cables, power cables and encoder cables from the controller to the driver for wiring errors, damage or poor contact;

c, check whether the brake of the servo motor with brake has been opened; Monitor the panel of the servo driver to confirm whether the pulse command is input;

d. The Run command is normal;

e, control mode must select the position control mode;

f. Whether the input pulse type set by the servo driver is consistent with that set by the command pulse;

g. Ensure that the forward side drive is prohibited, the reverse side drive is prohibited signal and the deviation counter reset signal is not input, the load is removed and the no-load operation is normal, and the mechanical system is checked.

4. How to deal with the overload of servo motor without load report? If the servo Run signal is connected and occurs without pulse: Check the servo motor power cable wiring, check for poor contact or cable damage.

Ori drive maintenance method:

1. Maintenance of the drive board

The structure of the drive board is basically the same as that of the inverter, which is composed of switching power supply, protection circuit, PWM wave isolation drive and three-phase inverter bridge. The maintenance principle and method can be referred to the frequency converter. Start from the fault, check the inverter fault, starting circuit fault, driving intentional fault, switching power supply fault.

2. Maintenance of control board

This board is more complex, generally composed of DSP and CPLD two main control chips. Includes current sampling, A/D, encoder signal processing.

DSP power supply system, I/O system, relatively speaking, the failure rate of the board is low, mainly to understand the meaning of the main parameters, which is very helpful for maintenance. Maintenance should make good use of the parameter tool.

3, display board maintenance

This is mostly composed of resistors and digital tubes, and rarely broken.

4, motor maintenance

For the incremental type is easier, hand turn the motor rotor, use the oscilloscope to measure the code disk output signal can be. You can read the numbers with a logic analyzer. Positive and negative turn, the number can add or subtract!
