MECHATROLINK-II-compatible AC Servomotors/Servo Drives
One Cable Enables Setting and Monitoring Parameters
Connect the PLC and Servo Drive with a single cable to reduce
wiring. What's more, the parameters for many Servo Drives can
be set and monitored at the same time between a personal
computer and the Controller.

Advanced Functionality!
Reduce Mechanical Vibration
Flexible Application
Quick suppression of vibration with an adaptive filter.
Even if the resonant frequency changes, realtime evaluation
automatically follows the changes to reduce the effect of vibration
due to low mechanical rigidity, such as for conveyer belts.
Automatically adjusts filter
to vibration frequency.
Change the command control mode as
required by the application.
Select from position control, speed control, and torque
control for use in applications such as the pressing,
tension, and injection.

Reduce Tact Time
Reduce mechanical vibration with the
vibration control function.
By removing the vibration frequency components between the stop position
and the intermediate position, vibration that occurs due to low mechanical
rigidity can be suppressed. (Control for two vibration frequencies)
