QD74MH□Series Features
Many functions required in a positioning control system, such as positioning control to arbitrary positions and constant-speed control, are provided.
This is an ideal positioning unit for systems comprising many axes but not requiring complex controls.
Perfect for simple positioning based on high-speed, linear control. Linear interpolation operations involving up to 4 axes are possible.
Comes with basic positioning functions such as electronic gears, backlash correction and an absolute position system.
- *□ in the above model name indicates the number of axes (8 or 16).

QD75MH□Series Features
Wire saving due to the due SSCNET III Cables and also permits connection distances of up to 50 m between stations.
An easily supported absolute positioning system where the origin position can be established by data-set type origin return.
In addition, the upper-limit LS / lower-limit LS / proximity dog signals can also be inputted to the servo amplifier, which achieves a significant wire saving.
