(1) There is no need to adjust the parameters, we can maintain the original parameters (default value) when the inverter leaves the factory.
(2) It is the parameter that needs to be set and changed before the trial operation.
(3) It is a parameter that is adjusted in the operation of the demand.
After the inverter is installed, disconnect its U V. W three output lines, and turn on the R S T input operation power supply of the inverter (pay attention to whether the additional operating voltage calibrated by the inverter is the same as the actual input voltage), different manufacturers have different names for some special terms, so it is necessary to be familiar with the user strategy of the newly purchased inverter. According to the parameter boundary, determine which parameters are consistent with the original operating conditions. For example, the additional frequency of the motor, the input voltage, the analog input and output signal types, etc., if these are combined with practice, can tacitly allow the factory settings of the inverter to be maintained. Some test runs have to re-change the provisioning. As; External terminal operation, minimum base frequency, maximum operating frequency, start time, stop machine start time (and method), motor overcurrent maintenance. There are also some parameters to be carried out according to the status of the operation. Such as work frequency, acceleration time, deceleration time, 1-stage speed, 2-stage speed, and 3-stage speed. The following parameters of the motor should be input into the parameters of the inverter. Such as the additional power, additional voltage, additional current, additional speed, etc., the input of these parameters is very critical and important, which will directly affect the normal play of some maintenance functions in the inverter, so it must be correctly input according to the signage parameters of the motor to ensure the normal operation of the inverter.
After replacing the inverter, it is necessary to set some parameters before the inverter can operate, and at least the following parameters should be set: 1. Enter the motor nameplate parameters, including additional voltage, additional speed, power, etc. 2. Set the control method, some are called macro settings, and select the corresponding control method according to the control schematic. This setting is actually the boundary of setting the relevant I/O interface. 3. Set the speed control parameters, including AI channel selection, signal type (4-20mA or 0-10V), and upper and lower limits. After the above parameters are set, it can be turned and used, and the following parameters are recommended to be set to optimize the equipment: output current limiting, torque limiting, speed limiting and other limiting parameters to avoid burning the motor. Maintenance parameters such as low-voltage maintenance and overcurrent maintenance. Optimize the execution method of different alarm signals, don't jump at every turn. The anti-swaying related parameters are optimized to improve the anti-swaying ability of the inverter.
