Synchronization with Motion Control: Multi-CPU high-speed communication cycles are synchronized with motion control, maximizing computational efficiency and ensuring precise coordination between logic and motion tasks.

Enhanced Motion Control Performance: The new motion control CPU delivers twice the performance of its predecessor, ensuring high-speed, accurate machine control.

Trigger Signal for Servo Amplifier Control: The arrival signal (in-position signal) from the servo amplifier used in the motion CPU is utilized as a trigger. This allows the programmable controller CPU to issue a start command to a second-axis servo amplifier, and the time from command issuance to the output of the speed command from the servo amplifier is measured. This time serves as a key indicator of inter-CPU data transmission speed, reflecting the system’s efficiency in real-time axis coordination.

Conclusion: The Q12PRHCPU is a robust, high-speed, and highly reliable redundant CPU module, ideal for applications demanding continuous operation, precise multi-axis control, and advanced process automation.
