HCFA Hechuan Servo Fault Code SV-X2E Series Fault Alarm Reasons and Solutions

Alarm reason and treatment measures

Err.001: Abnormal system parameters

Reasons: 1. The voltage of the control power supply drops instantaneously; 2. After the driver software is upgraded, the range of some parameters has been changed, causing the previously stored parameters to exceed the upper and lower limits.

Treatment measures: 1. Ensure that the power supply voltage is within the specification range, and restore the factory parameters (P20.06 is set to 1); 2. If the software is upgraded, please restore the factory parameters first.

Err.002: Product model selection failure

Reasons: 1. The encoder cable is damaged or the connection is loose; 2. Invalid motor model or driver model.

Treatment measures: 1. Check whether the encoder wiring is normal and ensure that the wiring is firm; 2. Replace it with a valid motor model or driver model.

Err.003: Error in parameter storage

Reasons: 1. The parameters are read and written too frequently; 2. The parameter storage device is faulty; 3. The control power supply is unstable; 4. The drive is faulty.

Treatment measures: 1. The upper device uses communication to modify parameters and write to EEPROM too frequently. Please check whether there is an instruction to frequently modify parameters and write to EEPROM in the communication program; 2. Check the control electrical wiring, and at the same time ensure that the control power supply voltage is within the specification range.

Err.004: FPGA failure

Cause: The software version is abnormal.

Action: Check whether the software version matches.

Err.005: Product matching failure

Reasons: 1. The encoder cable is damaged or the connection is loose; 2. Unsupported external interfaces such as encoders are used; 3. The power of the motor model and the driver model do not match; 4. The product model code does not exist.

Treatment measures: 1. Check whether the encoder wiring is good; 2. Replace the mismatched products; 3. Select the correct encoder type or replace other types of drivers; for example, the power level of the motor model set is greater than the power level of the drive, or This fault will be reported if the power level of the set motor model is more than two levels worse than that of the drive.

Err.006: Program exception

Reasons: 1. Abnormal system parameters; 2. Internal fault of the drive.

Remedy: EEPROM fault, restore factory parameters (P20.06 is set to 1), and power on again.

Err.007: Encoder initialization failed

Cause: The encoder signal is abnormal when it is powered on.

Action: Check the encoder wiring, or replace the encoder cable.

Err.008: Detection fault of short circuit to ground

Reasons: 1. The UVW wiring is wrong; 2. The motor is damaged; 3. The driver is faulty.

Treatment measures: 1. Check whether the UVW cable is short-circuited with the ground, and if so, replace the cable; 2. Check whether the resistance of the motor line and the resistance to ground is normal, if abnormal, replace the motor.

Err.009: Overcurrent fault A

Reasons: 1. The command input is synchronized with the servo on or the command input is too fast; 2. The external braking resistor is too small or short-circuited; 3. The motor cable is in poor contact; 4. The motor cable is grounded; 5. The motor UVW cable is short-circuited; 6. The motor is burnt out; 7. The software detects the overcurrent of the power transistor.

Treatment measures: 1. Check the command input sequence, and input the command after the servo is turned on "ordy"; 2. Measure whether the resistance value of the braking resistor meets the specifications, and re-select a reasonable braking resistor according to the requirements of the manual; 3. Check the cable connector 4. Check the insulation resistance between the UVW wire of the motor and the motor ground wire and replace the motor when the insulation is poor; 5. Check whether the UVW connection of the motor cable is short-circuited, and connect the motor cable correctly; 6. Check the motor Check whether the resistance value between the cables is the same, if they are different, replace the motor; 7. Reduce the load. Increase the capacity of the driver and motor, and prolong the acceleration and deceleration time.

Err.010: Overcurrent fault B

Reasons: 1. The command input is synchronized with the servo on or the command input is too fast. 2. The external braking resistor is too small or short-circuited. 3. The motor cable is in poor contact. 4. The motor cable is grounded. 5. The motor UVW cable is short-circuited. , The software detects the overcurrent of the power transistor.

Treatment measures: 1. Check the command input sequence, and input the command after the servo is turned on "ordy"; 2. Measure whether the resistance value of the braking resistor meets the specifications, and re-select a reasonable braking resistor according to the requirements of the manual; 3. Check the cable connector 4. Check the insulation resistance between the UVW wire of the motor and the motor ground wire and replace the motor when the insulation is poor; 5. Check whether the UVW connection of the motor cable is short-circuited, and connect the motor cable correctly; 6. Check the motor Check whether the resistance value between the cables is the same, if they are different, replace the motor; 7. Reduce the load. Increase the capacity of the driver and motor, and prolong the acceleration and deceleration time.

Err.012: Incremental photoelectric encoder Z disconnection or absolute encoder turns abnormal

Reason: Incremental encoder: 1. Abnormal reception of Z signal, Z signal is lost due to poor wiring of Z signal line or encoder fault; Absolute encoder: 2. Insufficient battery power supply of absolute encoder; 3. Parameter P06.47 = 1 (set as absolute system), the encoder initialization operation is not performed; 4. During the power-off of the drive, the encoder motor terminal wiring is unplugged.

Treatment measures: 1. Manually rotate the motor shaft, if the fault still occurs, check the encoder wiring, rewire or replace the cable, or replace the encoder and power on again; 2. It is necessary to determine whether the battery is normal. If the battery voltage is insufficient, please Replace the battery; 3. Set P20.06 = 7 to initialize the number of laps, and power on again; 4. Set P20.06 = 7 to initialize the number of laps, and power on again.

Err.013: The encoder communication is abnormal

Reasons: 1. The communication encoder is disconnected; 2. The encoder is not grounded; 3. The communication check is abnormal.

Solutions: 1. Check the encoder wiring, or replace the encoder cable; 2. Check whether the encoder is well grounded.
