Mitsubishi inverter has many setting parameters, each parameter has a certain selection scale, and the inverter can not work normally due to improper setting of a single parameter in the application. Let's take a look at the Mitsubishi inverter parameter setting operation.
1. Mitsubishi inverter work supervision and selection
1. The standby status is now frequency supervised
2. Press the SET button to enter the current supervision
3. Press the SET button in 2 conditions to enter the voltage supervision
4. Press the SET button in 3 conditions to enter the alarm supervision
5. Press the SET button in 4 conditions to enter the frequency supervision
Second, the selection of the working form of Mitsubishi inverter
1. Display the supervision form in the standby state
2. Press the MODE button to enter the frequency setting form
3. Press the MODE key in 2 conditions to enter the parameter form
4. Press the MODE button in 3 conditions to enter the working mode
5. Press the MODE button in 4 situations to enter the assistance mode
6. Press the MODE button in 5 conditions to return to supervised mode
3. Introduction to the main parameters of Mitsubishi inverter
1. Capped Frequency (Pr. 1)
The upper limit of the output frequency of the inverter is constrained, and the factory setting is 120Hz
2. Lower Limit Frequency (Pr. 2)
Constrain the lower limit of the output frequency of the inverter, only need to start the signal as ON, and start the motor when the frequency reaches the lower limit
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 prohibits picking (Pr. 77) Set to 1 during operation to prevent 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. Rotation prevention pick (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 keys to increase and decrease the setting frequency
3. Press the SET key to write the set frequency. The letter F appears on the screen shining ice, and the setting is successful
