Position control units
Point-to-point positioning controller with
pulse train output and motion control unit
functionality
• Position control units with 2 or 4 axes
• Position and speed control
• Linear interpolation and feeder control function
• Electronic CAM profiles and axes synchronization
• Positioning of 500 points per axis done from
memory
• S-curve acceleration/deceleration, origin search,
backlashcompensation, and other features are also
supported.
• Programming languages: ladder, function blocks.
• Use Windows-based support software to easily cre-
ate positioning data and store data and parameters
in files.
These position control units support positioning control via pulse-train outputs. Positioning is performed using trapezoidal or S-
curve acceleration and deceleration. Models are available with 2 or 4 axes control, and can be used in combination with servo
drives or stepping motors what accept pulse-train control. When these units are used in a CJ2 PLC CPU can perform also
synchronous operation by use of electronic CAMs and other function blocks.
