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.
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 MR-J40A PDF MR-J40A
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 MR-J40A PDF.
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. Type: MR-J series.
Rated output: 0 MR-J40A PDF. 6KW.
Applicable motor series: HA-FF, HA-SE.
Voltage: three phase AC220V.
It is very helpful to improve the stability of the low speed control of the servo motor.
But there is no direct effect to improve the accuracy of position control.
There are, of course, software compensation that is similar to pitch compensation,
Can improve the physical resolution of the single lap, so as to improve the accuracy of positioning control.
This can be effectively used in the use of the robot control of the indexing table.
It is also because of the application of splicing technology,
The rotary encoder will be more widely ussed in the high precision servo control in the harsh environment MR-J40A datasheet.
The use of rotary encoder with 224/ in the servo motor has been used in the servo motor.
Encoder serial communication system, the communication frequency can only bee limited to 10M MR-J40A datasheet. Specification: allowed regeneration power: 500W, resistance value: 13 ohm.
Uses: MR-JE-200B, MR-JE-300B, MR-JE-200A, MR-JE-300A with.
