MITSUBISHI QJ71DN91

MITSUBISHI inverter FR-F720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 22KW.
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%) QJ71DN91
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 QJ71DN91. 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 . MITSUBISHI motor universal AC servo amplifier MELSERVO-J3 series.
Rated output: 15.0kw.
Interface type: SSCNET type III fiber communication.
Special features: integrated driver security QJ71DN91.
Power specification: three phase AC400V .
STO function as a security feature is added to the SSCNET III fiber communication type servo amplifier.
By using the STO function, the electromagnetic contactor used in the past to prevent the motor from accidentally starting is no longer needed.
SS1 functions can be realized by using the MR-J3-D05 security logic unit.
MR-J3-BS uses a full closed loop control system.
Compatibility with MR-J3-B.
MR-J3-BS installation, wiring and connectors are the same as the MR-J3-B, so do not change the exiisting connection will be eaasy to MR-J3-B
Change to MR-J3-BS QJ71DN91.
Security functions are connected to the CN8 interface through an external security circuit to increase the MR-J3-BS driver security.
Compatible full closed loop control system.
MR-J3-BS has a full closed loop conttrool system version QJ71DN91. The length of the line: 20M.
IP level: IP67.
Bending life: high bending life.
Encoder cable for 15K1M, 11K1M4, HF-JP11K1M, 15K1M4.
