MITSUBISHI inverter series: FR-F820.
Voltage level: three phase 200V.
Power: 7.5kw.
SLD converter rated current: 49A.
Structure and function: Standard model.
Type: CA.
Substrate coating: have.
Compatibility with existing models.
Transducer installation size and FR-F700 (P) series of the same, so you do not need to worry about the replacement operation MITSUBISHI MM-EFS371M.
(rectifier separation type will vary)
Also, but also through the use of options (FR-A8TAT), FR-F700 (P) series installed control loop terminal station MM-EFS371M
Built in 2 PID arithmetic. In the inverter can be PID control of the motor state at the same time, used in the control of the external machine.
No external PID controller is used to control the external machine, so the system cost can be reduced MITSUBISHI MM-EFS371M. Power: 0.4kw.
Purpose: high frequency braking resistor.
The use rate of the built-in regenerative brake of the transducer can be promoted.
When using the FR-ABR type brake resistor, the short circuit piece between the terminal PR-PX is removed. Does not remove the short circuit chip will lead to overheating of the brake resistor.
The utilization rate of the regenerative braking should be less than the allowable brake use rate in the above table MITSUBISHI MM-EFS371M.
With the operating frequency of the brake resistor to reach 300 degrees C or higher, it is necessary to take protective measures and cooling.
MYS type resistor can be used. But please pay attention to the allowable brake use rate MITSUBISHI Three phase 400V grade frequency converter.
Do not remove the terminal P/+ and P1 between the short circuit chip, in addition to connecting the DC reactor MITSUBISHI Three phase 400V grade frequency converter.
The installation of thermal relay, to avoid overheating and burn the braking resistor. Power: 280kw.
Purpose: to suppress the power harmonics.
Connected to the inverter input, can be used to improve the power factor, reduce the input side of the high harmonic current MITSUBISHI Three phase 400V grade frequency converter.
According to the motor powerr used to select AC reactor MM-EFS371M.
(when the inverter capacity is greater than the motor capacity, is still based on the motor capacity to choose.) Power: 220kw.
Voltage: 400V.
The power factor of the input power factor is up to 0.999 and above (100% load) MITSUBISHI MM-EFS371M.
Can be connected to multiple inverters, to achieve a common DC bus mode.
Equipped with standard power retrogradation function.
