Programmable Controllers
MELSEC-Q SERIES
Its powerful presence guides the Q Series to the top, where no PLC has ever been before.
With its nano-order speed basic command processes, the next generation MELSEC-Q Series dramatically improves system and machine performance.
As equipment and manufacturing facilities continue to evolve on a daily basis, the series enables high-speed, high-accuracy and large volume data processing and machine control.
Concept
Current production requirements are calling for an increase in productivity and carrying out production processes even faster due to an increase in production information such as production results and tractability.
The MELSEC-Q Series programmable controller "Universal model QnU" is a leader for these market needs. High-speed basic instruction processing on a micro scale dramatically increases your system and machine performance.
Inheriting the high robust and ease of use design of the Q Series, the MELSEC QnU programmable controller will open up new possibilities in automation solutions.
Allows for detailed power measurement at high speed (250 ms)
• Allows for easy specific energy consumption*3 management by matching the "production information" of the CPU module with the "energy information" of the energy measuring module.
• Since measured data is automatically collected in a buffer memory at 250 ms, detailed specific energy consumption management is also available.
*3: The specific energy consumption is a numerical value displayed by "dividing energy consumption by production volume," which is one type of index that measures energy productivity. Improving this number leads to improved productivity and energy conservation.
Allows for easy construction of a "visualization" system
• Allows for easy graphic display of specific energy consumption with a GOT (HMI) installed on the control panel at the manufacturing site.
• Combination with the "high-speed data logger module (QD81DL96)" allows specific energy consumption analysis to be easily performed with a personal computer.
Advanced control but simple use as the positioning module
Speed/torque control and synchronous control are supported in addition to the traditional positioning control. Using the "simple motion module setting tool", operations such as positioning setting, monitoring and debugging can be performed easily. In addition, data synchronized with the motion controller can be collected and displayed in waveform.
CC-Link IE Field Network connection typeQD77GF4QD77GF8QD77GF16
The simple motion module supports the general purpose CC-Link IE Field Network, with its flexible wiring. This module can be used as the CC-Link IE Field's master station*1 while retaining the simple motion module's functions. This realizes flexible networking supporting connection to various devices such as GOT(HMI), remote I/O, inverter, etc.
*1: QD77GF4, QD77GF8, QD77GF16 master station transmission style can use the line type or star type. Up to 104 slave devices can be connected to one network.
*2: The setting and diagnosis function using GX Works2 is disabled.
