MITSUBISHI FR-A720-55K INSTRUCTION MANUAL (Applied) PDF

Can be isolated from the output of the programmable controller, the a/b/c contact relay, SSR, Tr output.Connecting cable for handheld RH GOT and PLC.
Cable length: 10 meters FR-A720-55K PDF.
Application: RS-422 connection and RS-232C connection. MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 250KW.
The main circuit of the inverter can be divided into two categories in general: voltage type is the voltage source of the DC converter for AC inverter,
The filtering of the DC circuit is the capacitance; the current mode is the DC conversion of the current source to the AC inverter,
The DC loop filter is the inductor FR-A720-55K PDF FR-A720-55K
Why is the frequency of the inverter voltage proportional to the change?
The electromagnetic torque of any motor is the result of the interaction between the current and the magnetic flux, the current is not allowed to exceed the rated value, otherwise it will cause the heating of the motor FR-A720-55K PDF.
Therefore, if the magnetic flux decreases, the electromagnetic torque will decrease, which leads to the reduuction of the load carrying capacity FR-A720-55K Manual. Input / output type: DC input (drain / source).
Input and output points: 16 points.
DC5V internal consumption current: 100mA MITSUBISHI INSTRUCTION MANUAL.
DC24V internal consumption current: 85mA.
In order to extend the input output of the device.
Also has a built-in power supply products.
The maximum number of points for the input and output is 256.
Expansion module: up to 16 units (in addition to the power expansion module)
The total number of CC-Link, AnyWireASLINK, and Bitty series of remote I/O is 512 points MITSUBISHI INSTRUCTION MANUAL. Power: 7.5kw.
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 MITSUBISHI INSTRUCTION MANUAL. 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.
With the operating frequency of the brake resistorr to reach 300 degrees C or higher, it is necessary to take protective measures and cooling FR-A720-55K INSTRUCTION MANUAL.
MYS type resistor can be used. But please pay attention to the allowable brake use rate.
Do not remove the terminal P/+ and P1 between thhe short circuit chip, in addition to connecting the DC reactor FR-A720-55K Manual.
The installation of thermal relay, to avoid overheating and burn the braking resistor.
