MITSUBISHI QD62

Drive: MR-H_ACN series built-in positioning function.
Rated output: 15KW.
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 QD62
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 QD62.
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. SI/QSI/H-PCF/ broadband H-PCF optical cable QD62.
Double circuit.
Controller network (control station / common station) / remote I/O network (remote master station).
With external power supply function.
MELSECNET/H network module capable of composing large scale flexible network system.
The MELSECNET/H network system includes the PLC network of the control station and the communication between the stations and the remote I/O network in the remote station remote I/O station.
Optical fiber loop system...... High speed communicationn of 10Mbps/25Mbps is realized QD62.

The distance between stations, the length of the total cable length, strong anti-interference .
Coaxial bus system...... Using low cost coaxial cable, the network construction cost is lower than that of the optical fiber loop network.
Twisted pair buus system QD62. ..... Combined with high performance price ratio network module and twisted pair cable,
The construction cost of network system is very low.
