Mitsubishi inverter has many setting parameters, each parameter has a certain selection range, and the use of individual parameters is often improper, resulting in the inverter can not operate normally. Let's take a look at the Mitsubishi inverter parameter setting operation.
1. Mitsubishi inverter operation supervision and selection
1. Standby is now frequency supervised
2. Press the SET button to enter the current supervision
3. Press the SET button in state 2 to enter the voltage supervision
4. Press the SET button in state 3 to enter the alarm supervision
5. Press the SET button in state 4 to enter the frequency supervision
Second, the selection of Mitsubishi inverter operation form
1. Manifest the form of supervision in standby mode
2. Press the MODE button to enter the frequency setting form
3. Press the MODE key in state 2 to enter the parameter form
4. Press the MODE button in state 3 to enter the working mode
5. Press the MODE button in state 4 to enter the help form
6. Press the MODE button in state 5 to return to supervised mode
3. Introduction to the main parameters of Mitsubishi inverter
1. Capped Frequency (Pr. 1）
Limit the upper limit of the output frequency of the inverter, and set it to 120Hz at the factory
2. Lower Limit Frequency (Pr. 2）
Limit the lower limit of the output frequency of the inverter, as long as the starting signal is ON and the frequency reaches the lower limit, the motor will be started
3. Acceleration and deceleration time setting
Pr。 7. Speed up the moment Pr. 8. Deceleration moment Pr. 44 Second Acceleration Moment Pr. 45 second deceleration moment
4. Electronic Overcurrent Maintenance (Pr. 9) The factory setting value is the rated current of the inverter
5. Applicable load selection (Pr. 14）
The constant torque load (conveyor, trolley, etc.) is set to 0
The low torque load (fan, pump, etc.) is set to 1. The factory setting value is 1
6. Parameter Writing Stop Picking (Pr. 77) Set to 1 when working to avoid misoperation
Only if the abort write setting is 0. Factory set to 0
No, the write setting value is 1
Even if you work, you can write a set value of 2
7. When operating with a voltage input signal (Pr. 73）
When using voltage input to operate a signal, set the frequency of the 2-5 button of the terminal to set the standard of the voltage signal.
1) When DC is 0-5V, the setting value is Pr. 73=1 (factory setpoint)
2) When DC is 0-10V, set Pr. 73=0
When the operation signal is input with a current, the input signal between terminals 4 and 5 is shorted, and the terminals AU-SD are shorted
8. Frequency setting: Setting voltage (current) gain
Frequency-set voltage gain (Pr. 903) 60Hz at 5V (or 10V) DCs
Frequency Setting Current Gain (Pr. 905) 0Hz at DC4ma, 60Hz at DC20ma
9. Swing to avoid picking (Pr. 78）
It is used for machinery that only works in one direction, e.g. fans, pumps
The positive rotation can be set to 0, and the factory setting value is 0
The no-turn setting is 1
The rotatable setting is 2
Fourth, Mitsubishi inverter. Frequency settings
1. Select the frequency setting form first
2. Press the up and down arrow keys to add to decrease the setting frequency
3. Press the SET key to write the set frequency. The screen flashes ice to render the letter F, and the setting is successful

Explanation of Mitsubishi pIc source type and drain type
The source type is the power supply of the device, which has an input drive source and an output point with a power supply; Drain type means that the device does not have its own power supply, and the drive of the input point requires an external power supply, and the output is only a passive contact signal.
The general input points are ...
