After the inverter is installed, disconnect the output of the inverter, use the diode file of the digital meter to measure the input and output of the inverter before powering on to ensure that there is no short circuit, and then turn on the working power supply of the inverter, (pay attention to whether the working power supply voltage calibrated by the inverter is consistent with the external input voltage), and confirm whether the factory settings and working conditions of the parameters are in accordance with the conditions, such as the rated frequency of the motor, the input voltage, the type of analog input/output signal, etc., if these signals are consistent with the working conditions, These parameters can be left unset and left at the factory.
There are some parameters that need to be preset before commissioning, such as: external terminal operation, analog operation, substrate frequency, *high frequency, upper frequency, lower limit frequency, start-up time, braking time (and mode), thermal electronic protection, over-current protection, carrier frequency, stall protection and over-voltage protection, etc.
There are also some parameters that are adjusted according to the operation during the debugging process, such as working frequency, acceleration time, deceleration time, 1-stage speed, 2-stage speed, 3-stage speed, analog output ratio adjustment, etc.
After the inverter is set, connect the motor, start the motor, given the speed, it should operate normally, pay attention to whether the DC bus voltage, the output current of the inverter, torque, power and other data are normal.

The cause of the damage of the inverter - Delta inverter
First, the heat dissipation of the inverter is not good
In fact, we all know that too high a temperature has a damaging effect on any equipment, just like a human brain, too high a temperature will also burn out the brain, in fact, the same is true for inverters. When the temperature rises, because of the sensitivity of semiconductors to temperature, the inverter ...

Productivity maintenance tips for Delta drives
1. When the Delta inverter breaks down in the future, it is best not to hand it over to someone who has no experience in repairing the inverter to repair the inverter, otherwise it may get worse and worse. Sometimes it's about to fuse, be sure to check whether there is a problem with the module, some electricians have not experienced it, and immediately install a good fast melt (definitely not ...

The inverter needs to be equipped with a braking resistor-Delta
The inverter is equipped with a braking resistor, mainly to consume part of the energy on the DC bus capacitor through the braking resistor to avoid the voltage of the capacitor being too high. Theoretically, if the capacitor stores a lot of energy, it can be used to release it to drive the motor to avoid energy waste, but the capacity of the capacitor is limited.
