MITSUBISHI motor universal AC servo amplifier MELSERVO-J3 series.
Rated output: 7.0kw.
Interface type: SSCNET type III fiber communication.
Special features: integrated driver security.
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 existing connection will be easy to MR-J3-B
Change to MR-J3-BS.
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 control system version.
Motor series: medium inertia, medium capacity.
Using a serial absolute / incremental encoder.
Rated output power: 1.2kw.
Rated speed: 1000rpm.
With the brake: without.
Shaft end: straight shaft.
The structure of the AC servo motor stator is basically similar to the capacitor split phase single-phase induction motor MITSUBISHI MR-J3-700BS4.
The stator is provided with two positions of 90 degrees of mutual difference of the winding, one is the excitation winding Rf, it is always connected to the AC voltage Uf;
The other is to control the winding L, which is connected to the control signal voltage Uc
MR-J3-700BS4
So the AC servo motor, also known as the two servo motor. The length of the line: 5M.
IP level: IP65.
Cable outlet direction: the same side of the motor shaft MITSUBISHI MR-J3-700BS4.
Bending life: high bending life.
Encoder with cable (motor side); for HF-KP/HF-MP series (motor shaft with side extraction). Motor series: low inertia, medium and small capacity.
Using a serial absolute / incremental encoder.
Rated output power: 5.0kw.
Rated speed: 2000rpm.
With a brake band.
Shaft end: straight shaft.
Comparison of single phase induction motor and servo motor MITSUBISHI MR-J3-700BS4.
The working principle of the AC servo motor is similar to that of the single phase induction motor,
But the rotor resistance of the former is much larger than that of the latter,
So the servo motor is compared with the single machine asynchronous motor,
There are three notable features:
1, large starting torque.
2, a wide range of operation.
3, no rotation phenomenon.
AC servo motor running smoothly, low noise.
But the control characteristic is non-linear, and because the rotor resistance is big, the loss is big, the efficiency is low,
Therefore, compared with the same capacity DC servo motor, the volume is large and the weight is heavy,
So it is only suitable for 0.5-100W small power control system. "MITSUBISHI general purpose AC servo amplifier MELSERVO-J2-Super series.
Rated output: 5.0kw.
Built in positioning function.
Voltage: 3 phase AC200VAC or single phase AC230V.
Compatible with "MR-J2S- CP-S084" - servo amplifier and interface unit "MR-J2S-TO1" positioning by CC-Link
Simply setting the point table MR-J3-700BS4.
AC servo can be used as the driving source of the field network.
Using servo amplifier built-in positioning function, position data and speed data, you can set the CC-Link.
Start, stop and dissplay can also be transmitted through the CC-Link MR-J3-700BS4.
Serial communication reduces wiring.
AC servo distributed control system can be easily constructed. "
