Controllers MELSEC-Q Series
Product features -Simple motion, Positioning-
Positioning
A large selection of motion control solutions are available to fit any motion application.
High-speed, accurate positioning control
Various types of motion control are supported including 2 to 4-axis linear interpolation, 2-axis circular interpolation, speed control, speed/position changeover, path control and constant speed control. Making settings (including positioning data), monitoring, and debugging is made much easier using GX Works2's built-in intelligent function module tools or the stand-alone tool, GX Configurator-QP. For servo control, Q Series leverages the benefits of SSCNET, a Mitsubishi high performance motion control network. This allows Mitsubishi intelligent digital servos to be connected by a simple daisy chain cable that reduces cost and increases performance.
Positioning module
- Open collector pulse train output type
- Differential driver pulse train output type
For compatibility with the widest range of motion hardware, both open collector and differential driver type positioning modules are available. Transmission of high-speed pulses, up to 4 Mpps, to a servo amplifier can be made reliably up to 10 meters away. These pulse train output positioning modules can provide a high level of speed and accuracy for practically any application.

The ideal solution for simple multi-axis positioning
These modules are ideal for high-speed linear positioning control in a multi-axis system.
Easily satisfying the requirements for simple positioning control applications, these modules include functions, such as positioning control, speed control and variable positioning control.
Positioning module
- Open collector pulse train output type
- Differential driver pulse train output type
These modules are a great match for stepper motor control. Acceleration and deceleration can be performed smoothly with very fine changes in speed. “Fast start processing” is a basic feature that allows for a single axis positioning start time of just 0.1 ms.
