THE “JUNIOR”:
A SINGLE AXIS SERVO
THAT FITS IN THE
PALM OF A HAND

The application of a higher performance CPU has enhanced response significantly. Speed loop frequency response raised to 550Hz or more (2 times faster than previous models). The MR-J2-Super series units are the best for use in high speed motion control applications.

The use of a higher resolution encoder ensures higher performance and smoothness at low speeds. Motor sizes are the same as previous products and wiring is compatible. Just like the standard MR-J2 motors, the “absolute encoder” is now the standard.

The HC-KFS series miniaturized motor is the same size as the HC-MFS series, yet the motor inertia moment is 3-5 times larger. This makes them suitable for machinery with load/motor inertia moment ratios too high for the HC-MFS, as well as machinery with low rigidity (belt-driven, etc.)

Even when acceleration/deceleration torque is low or friction on a vertical axis is large, the load/motor inertia ratio moment is adjusted to the optimum value automatically.

Typically, servo system performance is restricted by machine resonance. The adaptive vibration suppression control function breaks this barrier to give stability at all operating speeds.

Two suppression filter points can be set to match machine resonating points. This filter can be combined with the adaptive vibration suppression control function as well, however, only one point can be set for the machine resonance suppression filter at a time.

Simply connect the servomotor to the machine and the resonant frequency of the mechanical system can be analyzed. Analysis is completed in as little as 30 sec.

Machine Simulation Function

The results of the machine analyzer are read into a simulation model, and the response of the mechanical system can be predicted. Simulated waveforms of speed, torque and droop pulse etc., while changing the command pattern, servomotor capacity and gains, can be observed.

Gain Search Function

Software then changes gains automatically and searches out the values that ensure the shortest possible settling time with minimum overshoot and vibration. Ability is best shown when high-performance is required.
