Convert connector to screw relay terminal.
According to the location of the connection equipment distribution module. CC-Link interface module.
PLC FX can be used as the CC-LINK remote device station connection.
If using CC-LINK type FX2N-16CCL-M system master module,
So just PLC CC-LINK can build FX system FR-E540-0.75K-CH Manual FR-E540-0.75K-CH TECHNICAL MANUAL. MITSUBISHI inverter FR-F720 series FR-E540-0.75K-CH
Voltage level: three phase 200V.
Frequency converter capacity: 18.5KW.
When the inverter is running, the starting current and starting torque of the motor are how?
With the operation of the inverter, with the acceleration of the motor to improve the frequency and voltage,
The starting current is limited to 150% below the rated current (according to the different types of aircraft, 125%~200%) FR-E540-0.75K-CH Manual FR-E540-0.75K-CH TECHNICAL MANUAL.
Starting with power frequency power supply, the starting current is 6~7 times of the rated current, therefore, the impact on the mechanical and electrical.
The inverter drive can be smoothly start (start time longer).
The starting current is 1.2~1.5 times of the rated current, and the starting torque is 70%~120% rated torque;
For the inverter with the torque automatic enhancement function, the starting torque is more than 100%, which can start with full load FR-E540-0.75K-CH Manual FR-E540-0.75K-CH TECHNICAL MANUAL. Power: 2.2kw.
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.
With the operating frequency of the brake resistor to reach 300 degrees C or higher, it iss necessary to take protective measures and cooling FR-E540-0.75K-CH Manual FR-E540-0.75K-CH TECHNICAL 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-E540-0.75K-CH Manual FR-E540-0.75K-CH TECHNICAL MANUAL.
The installation of thermal relay, to avoid overheating and burn the braking resistor.
