Drive: MR-H_ACN series built-in positioning function.
Rated output: 3.5KW.
Rotor speed measurement accuracy is very important to improve the dynamic and static characteristics of the speed control loop.
In order to seek the balance between measurement precision and system cost, incremental photoelectric encoder is generally used as the speed measuring sensor,
The corresponding method is M/T velocity measurement.
Although the M/T measurement method has a certain measurement accuracy and a wide range of measurement,
Mainly includes: the measurement period must be detected at least one complete encoder pulse, limiting the minimum detectable speed.
2 control system for speed control of the timer switch is difficult to maintain synchronization,
Can not guarantee the accuracy of measurement in the situation where the speed change is larger.
Therefore, it is difficult to improve the speed tracking and control performance of servo drive by using the traditional speed loop design method.
Motor: HA-UH type.

According to the types of power supply: can be divided into DC motor and AC motor.
The structure and working principle of DC motor can be divided into four parts: brushless DC motor and brushless DC motor.
Brushless DC motor can be divided into: permanent magnet DC motor and DC motor MITSUBISHI MR-H350ACN.
DC Motor Division: Series DC motor, DC motor, DC motor and DC motor
MR-H350ACN
Permanent magnet DC Motor Division: rare earth permanent magnet DC motor, ferrite permanent magnet DC motor and aluminum nickel Gu Yongci DC motor. Drive: MR-H_ACN series SSC-NET compatible AC servo.
Rated output: 0.4KW.
The servo controller can easily transfer the operation module and the field bus module through the automation interface,
At the same time using different fieldbus modules to achieve different control modes (RS485, RS232, optical fiber, InterBus, ProfiBus),
And the control mode of general inverter is single MITSUBISHI MR-H350ACN.
The servo controller is directly connected with a rotary transformer or an encoder, which forms a closed loop of speed and displacement control.
The general inverter can only form an open loop control system MITSUBISHI MR-H350ACN.
Servo controller of the control parameters (such as steady-state accuracy and dynamic performance) is better than the general inverter. Motor series: medium inertia, medium capacity.
Using a serial absolute / incremental encoder.
Rated output power: 7.0kw.
Rated speed: 2000rpm.
With a brake band.
Shaft end: straight shaft.
The rotor of AC servo motor is usually made of squirrel cage, but in order to make the servo motor has a wide range of speed regulation, linear mechanical properties,
Without the "rotation" phenomenon and the performance of the fast response, it is compared with the ordinary motor,
The two characteristics of rotor resistance and moment of inertia should be provided MR-H350ACN.
At present, there are two kinds of rotor structure, one is the squirrrel cage rotor, which is made of conductive material with high resistivity,
In order to reduce the moment of inertia of the rotor, the rotor is slender MR-H350ACN.
