Advanced Industrial Automation
Save space, save wiring, save time
Easy connection: single cable only!
With their built-in MECHATROLINK-II motion
bus, just a single cable is needed to connect
servos together. So you not only save
on wiring and installation time, you also
significantly reduce the chance of connection
errors. Reliability is increased since the single-
cable connection is much more rugged than
a multiple-wiring solution.

Tuning-less: just connect and run!
The advanced technology embodied in the Junma ML-II series
makes the dream of the no-tuning servo solution a reality.
No gain parameters need to be set. Just connect up to the motor
and you’re ready to go.
The “Tuning-Less” algorithm consists of two major components:
• adjusts internal speed loop calculation to always obtain the
same response characteristics
• “Auto Notch” changes parameters in the notch filter in order
to suppress mechanical resonance
Tuning-Less effect example
The test is done with a rotor inertia ratio of 0% (no load) and
1000% (load inertia 10 times rotor).
The graphs are showing position deviation and output torque
test results, where the same dynamic response is achieved.
