Type: HC-PQ type.
Output power: 0.4kw.
Rated speed: 3000r/min.
Electromagnetic brake: No.
Key axis: straight shaft.
Motor aspects: the material, structure and processing technology of the servo motor is much higher than that of AC motor,
That is when the driver output current, voltage, frequency change is fast power supply,
The servo motor can change according to the change of the response of the power supply,
Response characteristics and anti overload capacity is much higher than the AC motor drive,
Motor aspects of the serious differences between the two are fundamentally different performance MITSUBISHI HC-PQ053D HC-PQ053D
That is not the inverter output can not change so fast power signal,
But the motor itself can not react,
So in the frequency of the internal algorithm set to protect the motor to do the corresponding overload MITSUBISHI HC-PQ053D.
Of course, even without the ability to set the output of the inverter is limited,
Some of the excellent performance of the inverter can be directly driven servo motor. Drive: MR-H_ACN series built-in positioning function.
Rated output: 11KW.
In servo drive speed closed loop,
Rotor speed measurement accuracy is very important to improve the dynamic and static characteristics of the speed control loop MITSUBISHI HC-PQ053D.
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 MITSUBISHI General motors for MR-JE and MR-E.
Although the M/T measurement method has a certain measurement accuracy and a wide range of measurement,
But this method has its inherent defects,
Mainly includes: the measurement period must be detected at least one complete encoder pulse, limiting the minimum detectable speed MITSUBISHI General motors for MR-JE and MR-E.
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 MITSUBISHI General motors for MR-JE and MR-E.
Therefore, it is difficult to improve the speed tracking and control performance of servo drive by using the traditional speed loop design method. Drive: MR-H_ACN series SSC-NET compatible AC servo.
Rated output: 15KW.
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 modde of general inverter is single HC-PQ053D.
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 ccontrol system MITSUBISHI HC-PQ053D.
Servo controller of the control parameters (such as steady-state accuracy and dynamic performance) is better than the general inverter.
