Host has 10 points (6I/4O), 14 points (8I/6O), 20 points (12I/8O), 30 points (16I/14O) of 44 types FR-A740-75K-CHT Manual .
This type of PLC is mainly used in all of the digital input, digital output control point of the device MITSUBISHI TECHNICAL MANUAL.
Can be directly connected to the 220V city power, built-in 8K step EEPROM memory, no battery, easy to maintain.
The series transistor output (MT) of the PLC, can be output 2 100KHz pulse, direct drive servo or stepper motor.
The series PLC can not be brought with the expansion module, but can be installed by the BD board to extend a small amount of I/O MITSUBISHI TECHNICAL MANUAL.
The series 1N through the installation of BD series PLC board, can achieve RS232, RS485, RS422 communication. 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.
Why is the frequency of the inverter voltage proportional to thhe 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 mmotor FR-A740-75K-CHT Manual FR-A740-75K-CHT TECHNICAL MANUAL.
Therefore, if the magnetic flux decreases, the electromagnetic torque will decrease, which leads to the reduction of the load carrying capacity.
