After the installation of the Delta inverter is completed, disconnect the output of the inverter, use the diode file of the digital meter to measure the input and output of the inverter before the power is not turned on to ensure that there is no short circuit, and then turn on the operating power supply of the inverter (pay attention to whether the operating power supply voltage calibrated by the inverter is consistent with the external input voltage), and recognize whether the factory settings of the parameters are consistent with the working conditions, such as the additional frequency of the motor, the input voltage, the type of simulated input/output signals, etc., if these signals are consistent with the operating conditions, These parameters can be set without setting, just stick to the factory settings.
There are some parameters that need to be preset before commissioning, such as: external terminal operation, analog quantity operation, substrate frequency, high frequency, upper and lower frequency, lower limit frequency, start-up time, braking time (and mode), thermoelectronic maintenance, overcurrent maintenance, carrier frequency, stall maintenance and overvoltage maintenance.
There are also some parameters that are adjusted according to the operation status during the commissioning process, such as operation frequency, acceleration time, deceleration time, 1-stage speed, 2-stage speed, 3-stage speed, imitation output share adjustment, etc. After the Delta inverter is set, connect the motor, start the motor, and at a given speed, it should operate normally, paying attention to whether the DC bus voltage, inverter output current, torque, power and other data are normal.
