Inverter maintenance and other series
When repairing the inverter, please look for the Shanghai Sixi Mechanical and Electrical Automation Technology Co., Ltd. inverter maintenance fault code
Speed up operation Overcurrent
Short acceleration time
Restart the rotating motor when an instantaneous stop occurs
External wiring error
Pulse encoder wiring error
Please extend the acceleration time
/> Wait for the motor to stop before starting
Correct wiring
Change the settings or replace the encoder wiring phase sequence
Frequency converter fault code
Overcurrent during deceleration
Deceleration Time is too short
Extend deceleration time, adjust parameters
Constant speed operation overcurrent
Load sudden change
Abnormal load
Adjust parameters
Perform load check
Overvoltage during acceleration of the inverter
Abnormal input voltage
Improper parameter setting
Load inertia is too large
Please check the input power supply
Adjust parameters
External system Dynamic resistor
Frequency converter fault code
Overvoltage during deceleration of the frequency converter
Short deceleration time
Improper selection of energy-consuming braking resistor
Abnormal input voltage
Improper parameter setting
Extend the deceleration time
Re-select the braking resistor
Check the input voltage
Adjust the parameters
Frequency converter fault code
The frequency converter has run at constant speed Voltage
The input voltage has changed abnormally
The potential load generates regenerative energy
Install the input reactor
External braking resistor
Inverter fault code
Output Phase loss
The three-phase output of the frequency converter is disconnected, the phase is missing or the three-phase load is seriously asymmetric
Check the three-phase output wiring or load symmetry of the frequency converter
The radiator is overheated
Wind Duct blocked
Abnormal
Clean the air duct
Seek service
Frequency converter overloaded
Overload
Grid voltage too low
Encoder abnormal
br/> Select the appropriate inverter
Check the grid voltage
Check the encoder wiring or replace the encoder

Tuning error
Motor nameplate parameter setting error
Tuning timeout
Press the motor nameplate Set the parameters correctly
Confirm whether the motor is disconnected from the load or check
Motor wiring
Parameter setting error
Door width self-learning is not set to manual debugging mode
The general panel operation mode is not set during motor parameter tuning
The door opening and closing operation time is set less than the sum of all door opening and closing time parameters
The door width is set during self-learning
The motor parameters are set during tuning< br/> Set a larger door opening and closing operation time to ensure it is greater than the sum of all door opening and closing time parameters
