Position Control Units
High-speed, High-precision
Positioning with 1, 2, or 4 Axes
• Simple positioning systems can be created by
directly specifying operation from the CPU Unit
when required.
• Positioning data is saved in internal flash memory,
eliminating the need to maintain a backup battery.
• Use Windows-based Support Software (CX-Posi-
tion) to easily create positioning data and store data
and parameters in files.
• S-curve acceleration/deceleration, forced starting,
and other features also supported.
- Position, speed and acceleration settings can be
changed during operation
- Speed and acceleration can be modified during
Jog operation
- Parameters and data are easily backed up to a
memory card in the CPU unit
Function
These Position Control Units support open-loop control with pulse-train
outputs. Position using automatic trapezoid or S-curve acceleration and
deceleration. Models available with 1, 2, or 4 axes. Use in combination
with servomotors or stepping motors what accept pulse-train inputs.
