MITSUBISHI MR-J4-700A4

Drive: MR-H_ACN series built-in positioning function.
Rated output: 7.0KW.
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-J4-700A4
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-J4-700A4.
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 MR-J4-700A4. 32: terminal line adapter 0 . 3mm2 (AGW22).Board module installation location: QS series power module mounting slot.
Suitable substrate module: QS034B.
Input power: AC100~120V.
Security PLC (secure programmable system) refers to the self or external components or the implementation of the failure of the agency,
Can still respond to and promptly cut off the output of the programmable system.
Different from ordinary PLC, security PLC not only can provide the function of ordinary PLC,
Safe control function can be realized,
Meet the requirements of the ISO 13849-1 EN and IEC 61508 control system safety related component standards.
PLC security market mainstream has oilz (Pilz) PSS 3000, PSS 4000,
PSS 4000 in addition to the secuurity process can also bee processed outside the standard control procedures MR-J4-700A4.
All the components in the security PLC adopt the redundancy structure,
Two processor processing for cross detection,
The processing results of each processor are stored in their respective memoryy,

Output is only when the processing result is in full agreement,
If any inconsistency occurs during the process, the system is immediately shut down MR-J4-700A4.
