What are the usual reasons for the drive alarm ERR1?
Please refer to the instruction manual for alarm and handling:
1. Alarm ERR1 immediately after power-on. If this is the case, please disconnect the power lines (U, V, W, PE) of the motor and the drive, and power on again. If the drive still reports ERR1, the power module of the drive is broken, please replace the drive. If the driver does not alarm ERR1, check whether the motor and power lines U, V, W and PE are short-circuited.
2. The alarm ERR1 during operation may be caused by improper adjustment of parameters by the user. Please consult the manufacturer to re-adjust the parameters.
What are the general reasons for the drive alarm ERR3?
Please refer to the instruction manual for alarm and handling:
1. The main circuit R, S, T is under voltage, please check whether R, S, T have 220v voltage, if the voltage is lower than 180v, the drive alarm.
2. The control circuit r and t are energized first, and the main circuit R, S, and T are energized later, which will also cause this situation. The main circuit of the servo driver must be energized before the control circuit.
What are the usual reasons for drive alarm ERR4?
Please refer to the manual for alarm and handling:
1. The external voltage is too high (the input power voltage is too high). Generally, the input power voltage of our driver is 220V (-15-10%), that is, after it exceeds 244V, the driver will alarm ERR4.
2. The resistance value of the external braking resistor is too large or the power is too small, which will cause the braking resistor to burn out. Generally, it is recommended to use a resistor with a larger power and a resistance value of about 30 ohms for frequent braking.
3. The driver B2P port short-circuit piece is not connected (that is, the built-in braking resistor is not connected).
4. The internal braking circuit of the driver is faulty, which is usually manifested as a short circuit of the MOS tube. The detection method is to connect an external braking resistor. In the case of no operation, the braking resistor heats up.
What are the general reasons for the drive alarm ERR8?
Please refer to the manual for alarm and handling:
1. The motor power line is not connected or the UVW phase sequence of the motor power line is reversed. Generally, the red power line of our factory is U-phase, green is V-phase, and blue is W-phase.
2. The encoder cable is damaged or the encoder is damaged.
Detection method: Rotate the motor shaft once by hand, and check whether the value inside dp-pos will change slowly from 0-10000 in the driver monitoring menu. If there is no change, the motor encoder may be damaged or the encoder wire may be connected. wrong.
3. The external machinery is stuck.
Inspection method: Loosen the load, if there is no problem with the motor idling, then check the mechanical structure.
4. Overspeed, the given pulse frequency is too high. The performance is that the drive does not alarm at low speed, and the drive alarms at high speed.
Detection method: Under dp-cs in the monitoring menu, check whether the external given speed exceeds the value set by parameter PN-023. If it exceeds, adjust the input pulse frequency, or increase the value set by PN-023.
5. The driver parameter gain setting is incorrect. It is manifested as occasional alarm ERR8 during work. Solution: Increase the value of p009.
What are the reasons for the drive alarm ERR11, ERR12, ERR13?
Please refer to the manual for alarm and handling:
1. The encoder cable is damaged or the encoder is damaged.
Detection method: Rotate the motor shaft once by hand, and check whether the value inside dp-pos will change slowly from 0-10000 in the driver monitoring menu. If there is no change, the motor encoder may be damaged or the encoder wire may be connected. Mistake.
2. Poor line contact: The driver occasionally alarms ERR11 and ERR12.
3. Drive problem, replace the drive.
What are the reasons for the driver alarm ERR15?
Please refer to the manual for alarm and handling:
1. The motor power line is not connected or the UVW phase sequence of the motor power line is reversed. Generally, the red of our factory power line is U-phase, green is V-phase, and blue is W-phase.
2. The drive output module is damaged.
Detection method: Use a multimeter to measure whether the voltages between U, V, and W phases are consistent. If they are inconsistent, it may be caused by the lack of phase of the module; if the test module outputs incorrectly, the module is damaged.
3. The external machinery is stuck.
Inspection method: Loosen the load, if the motor runs normally, check the mechanical part.
Fourth, the load is too large, the motor selection is too small. Choose a larger capacity motor.
Can the driver communicate with the touchscreen?
The driver can communicate with the touch screen. The driver adopts two communication data structures of standard MODBUS communication (including MODBUS-RTU and MODBUS-ASCII), and its communication address (for more details, please refer to the parameters and functions of the manual).
Can ESDA series and ESDB series drivers use single-phase 220V power supply?
ESDA series and ESDB series drivers can use single-phase 220V power supply, but three-phase 220V power supply is generally recommended.
Is it possible to hit the motor shaft directly when installing the synchro pulley?
Do not hit the motor shaft directly when installing the synchronizing wheel. Because the encoder is installed at the tail of the motor, and its code disc is made of glass, if it is directly knocked, it may cause the glass of the code disc to shatter, so it is generally tapped with a rubber hammer.
The PLC-controlled servo motor was normal at the beginning, but after a period of time, why does it
Please check whether the wiring is correct. PLC generally uses collector connection. Please refer to pages 14 and 15 of the manual. If external power connection is used, pulse ports (41, 43) and direction ports (37, 36) are not connected to 2000 ohms. If the resistance is 0.5 watts, the pulse port and the direction port of the driver will burn out after a period of time, and the direction port will burn out faster, so the motor will only rotate in one direction as described above.
The machine tool system is a new generation MA10 system, with pulse output, why does the servo motor
The default pulse output mode of each system is different. Now there are basically three pulse control modes on the market:
1. Pulse plus direction (such as Guangzhou CNC system and Kaiendi system, etc.)
2. AB pulse (such as new generation system and Baoyuan system, etc.)
The default of our driver is pulse plus direction. If the new generation MA10 system has pulse output, the parameter Pn-014 of our driver must be changed to 2. After saving the parameters, it needs to be powered on again to run, and it can be monitored under the dp-cpo menu. Pulse reception condition.
