2.3 Parameter viewing and modification methods

The operation panel of VXXX frequency converter adopts a three-level menu structure for parameter setting and other operations. The three-level menus are:

1) Functional parameter group (first level menu)
2) Parameters (secondary menu)
3) Parameter setting values (three-level menu)

After entering each level of the menu, when the display flashes, you can press the ▲ key, ▼ keyUse the key to make modifications. The operation process is shown in the following figure:

The three-level menu operation flowchart will display the parameters

a) When operating the third level menu, you can press the PRG key or ENETER key to return to the second level menu. The difference between the two is:

Press the ENTER key to save the set parameters and return to the secondary menu, automatically transitioning to the next parameter; Pressing the PRG key means discarding the current parameter modification and directly returning to the secondary menu of the current parameter number.

b) In the third level menu state, if the parameter does not have a flashing bit, it means that the parameter cannot be modified. Possible reasons include:

(1) This parameter is non modifiable, such as frequency converter type, actual detection parameters, operation record parameters, etc.

(2) This parameter cannot be modified during operation and can only be modified after shutdown.

2.4 Parameter Composition

parameter group	Functional Description	Instructions
P0 ~ PP A0~ AC	Basic Parameters	Operating instructions, frequency instructions, motor parameters, control mode, AI/AO characteristic calibration, optimization control and other parameters.
U0	Monitoring parameter group	Display of basic monitoring parameters for frequency converters.

Functional parameter table

The user password for the frequency converter is only used to lock the panel operation. After setting the password, when reading and writing parameters through the keyboard, password verification is required every time the user exits the operation and needs to re-enter; During communication operations, read and write operations can be performed directly without using a password (except for PP and PF groups). The parameter menu in user customized parameter mode is not password protected.

Group P and Group A are basic functional parameters, while Group U is a monitoring functional parameter. The symbol explanations in the parameter table are as follows:

“☆”The set value of this parameter can be changed when the frequency converter is in both shutdown and operation states;
“★”The set value of this parameter cannot be changed when the frequency converter is in operation;
“●”The value of this parameter is the actual detection record value and cannot be changed;
* ": This parameter is a" manufacturer parameter "and is only set by the manufacturer. Users are prohibited from operating it;

Fault diagnosis and countermeasures

1. Safety precautions

danger

It is strictly prohibited to connect wires while the power is turned on. Please make sure to keep all circuit breakers in the OFF state. Otherwise, there is a risk of electric shock.

Warning

Please ensure that the frequency converter is grounded in accordance with local regulations. Otherwise, there may be a risk of electric shock or fire hazard.
Do not disassemble the casing or touch the internal circuit of the frequency converter when it is powered on. Otherwise, there is a risk of electric shock.
Fault inspection must be carried out by professionals, and non professionals are strictly prohibited from inspecting, maintaining, and repairing the frequency converter. Otherwise, there may be a risk of electric shock or fire hazard.
When installing the frequency converter in a closed cabinet or casing, please use a cooling fan or cooling air conditioner to fully cool it, so as to keep the intake temperature of the frequency converter below 50 ℃. Otherwise, it may cause overheating or fire.
Please tighten all screws according to the specified torque. Otherwise, there may be a risk of fire or electric shock.
Please confirm that the input voltage of the product is within the rated voltage range on the nameplate, otherwise there may be a risk of electric shock or fire.

Attention

When performing installation work, please cover the upper part of the inverter with a cloth or paper to prevent metal shavings, oil, water, etc. from entering the interior of the inverter during drilling. If foreign objects enter the interior of the frequency converter, it may cause the frequency converter to malfunction.
After finishing the homework, please remove these cloths or papers. If it continues to be covered, it will deteriorate the ventilation and cause abnormal heating of the frequency converter.
When operating the frequency converter, please follow the steps specified for electrostatic discharge (ESD) prevention measures, otherwise the internal circuits of the frequency converter may be damaged due to static electricity.

2. Adjustment guide before trial operation of frequency converter

1) Open loop vector control mode (P0-01=0 factory default value)

This control mode is used to control the speed and torque of the motor in applications where there is no encoder speed feedback. In this control mode, self-learning of motor parameters is required to achieve automatic tuning of motor parameters.

Problems and malfunctions	Countermeasures
Overload or overcurrent fault reported during motor start-up process	The motor parameters (P1-01~P1-05) are set according to the motor nameplate. Perform motor parameter tuning (P1-37), and if conditions permit, it is best to perform dynamic and complete motor tuning.
Slow torque or speed response below 5Hz, motor vibration	To improve the response of torque and speed, it is necessary to strengthen the proportional adjustment of the speed loop (P2-00 increases the set value by 10 units) or reduce the integration time of the speed loop (P2-01 decreases by 0.05 units); If there is vibration, it is necessary to weaken P2-00 and increase the parameter value of P2-01.
Slow torque or speed response above 5Hz, motor vibration.	To improve the response of torque and speed, it is necessary to strengthen the proportional adjustment of the speed loop (P2-03 increases the set value by 10 units) or reduce the integration time of the speed loop (P2-04 decreases by 0.05 units); If there is vibration, it is necessary to weaken P2-03 and increase the parameter value of P2-04.
Low speed accuracy	When the speed deviation of the motor under load is too large, the vector slip compensation gain (P2-06) needs to be increased or decreased by 10%.
Large speed fluctuations	When there is abnormal fluctuation in motor speed, the speed filtering time (P2-07) can be appropriately increased in units of 0.001s.
The motor has loud noise	Appropriately increase the carrier frequency value (P0-15), increasing in units of 1.0KHz; (Note: Increasing the carrier frequency of the motor will increase the leakage current)
Insufficient motor torque or output	Is the torque upper limit restricted? Increase the torque upper limit (P2-10) in speed mode; Increase torque command in torque mode

2) Closed loop vector control mode (P0-01=1)

This mode is used in applications where the motor has encoder speed feedback. It is necessary to correctly set the number of encoder lines, encoder type, and signal direction to achieve automatic tuning of motor parameters.

Problems and malfunctions	Countermeasures
Start reporting overcurrent or overload fault	Correctly set the number, type, and direction of encoder lines
Overload or overcurrent fault reported during motor rotation	The motor parameters (P1-01~P1-05) are set according to the motor nameplate. Perform motor parameter tuning (P1-37), and if possible, it is best to perform dynamic and complete motor tuning.
Slow torque or speed response below 5Hz, motor vibration	To improve the response of torque and speed, it is necessary to strengthen the proportional adjustment of the speed loop (P2-00 increases the set value by 10 units) or reduce the integration time of the speed loop (P2-01 decreases by 0.05 units); If there is vibration, it is necessary to reduce the values of the P2-00 and P2-01 parameters.
Slow torque or speed response above 5Hz, motor vibration.	To improve the response of torque and speed, it is necessary to strengthen the proportional adjustment of the speed loop (P2-03 increases the set value by 10 units) or reduce the integration time of the speed loop (P2-04 decreases by 0.05 units); If there is vibration, it is necessary to reduce the values of the P2-03 and P2-04 parameters.
Large speed fluctuations	When there is abnormal fluctuation in motor speed, the speed filtering time (P2-07) can be appropriately increased in units of 0.001s.
The motor has loud noise	Appropriately increase the carrier frequency value (P0-15), increasing in units of 1.0kHz; (Note: Increasing the carrier frequency of the motor will increase the leakage current)
