Feature 1Superlative Performance

Operate your machinery faster and with higher precision than ever!

The Σ-V delivers the highest performance in the industry.



The best amplifier response in the industry slashes settling time

In-house comparison: 1/12^th


Peak torque has been boosted from 300% to 350%, contributing to shorter tact times

Standard use of high-resolution encoder has enabled high-precision and fine processing

Feature 2 Simple Start-up
Making servo adjustment quick and simple.
Let the Σ-V series simplify your life!


Easy tuning for each use

• New Tuning-less Function Settling time: 100 to 150 ms level No tuning required
• New "One-parameter" Tuning Settling time: 0 to 4 ms level Tuning time: 1/10 faster
• New Advanced Autotuning Settling time: 10 ms level
  Tuning time: 1/15 faster

Feature 3 Outstanding Expandability
Use servos that really fit into your system. A rich selection of models and options to match your requirements.


Extensive variety of motors to match any machine

• Medium-inertia servomotors Improved control stability
• Low-inertia servomotors High-speed acceleration and deceleration

Feature 1 Easy-Setup.
After unpacking and wiring the motor, just set the PULSE switch and it's ready to go.

• <Industry's First> No troublesome parameter settings with new parameter-less function.
• Setup time is greatly reduced. 7.5 times faster than the conventional.SERVOPACK. Shortened setup time like that for stepping motors greatly reduces operation time in production lines and in the field.

Feature 2 Easy-Tuning.

Just plug and play.

•     <Industry's First>No gain adjustments with tuning-less function.
•     Fine tuning with the FIL switch can correct overshooting.
•     Adjustment time is greatly reduced. 20 times faster than the conventional SERVOPACK.
•    As easy to use as a stepping motor even for first-time users.

Feature 3 Easy maintenance

• No maintenance is needed. Quick reaction to load changes with a constant automatic adjustment function.
• Easy to replace Replacement is easy with no adjustments and no specific tools required. (Substitute provided if a failure should occur.)

Feature 1 Superlative Performance.
The new SGMVH models provide the ultimate combination in compactness and low inertia with rated outputs from 22 to 75 kW and at rated speeds of 1500/800 min^-1.

Compared with SGMBH servomotors:
Moment of Inertia : 75 to 50%
Mass : 60 to 80%


Feature 2High-precision, high-efficiency SERVOPACKs
Our d-q conversion current control scheme improves torque control precision (repeatability) from ±5% to ±2%. Highspeed CPU processing and expanded control algorithms deliver extremely fast response to minimize tact time.

Feature 3 Simple implementation

The automatic motor identification function sets motor parameters for you, simplifying setup, and the following modules can be instantly connected to the SERVOPACK for quick network support (excluding 75 kW models).

MECHATROLINK-II : JUSP-NS115 Module
DeviceNet : JUSP-NS300 Module
PROFIBUS-DP : JUSP-NS500 Module

Feature 4Easy maintenance
Just connect to a PC for simple parameter definition/change/ backup, trace functions and other tools to make motor adjustment simpler than ever. If an alarm is generated, only the main circuit power supply is cut. The monitor function makes it possible to diagnose faults and identify causes quickly for minimum downtime.

Feature 1Automatic speed adjustment when load changes! Quick and efficient setup!

• Connect and go! Shared concept with other products in the JUNMA series.
  No troublesome parameter settings and gain adjustments needed.
• Equipped with a constant automatic adjustment function that quickly reacts to load changes, the JUNMA-II brings steady operation to applications with high frequency speed and torque changes.

Feature 2Added value with MECHATROLINK-II communications!

• Requires less space and less wiring. You can build the system to your own need because the YASKAWA AC servo drives, as well as various devices made by member companies of the MECHATROLINK Members Association, can be connected to your system.
• Startup time is greatly reduced by incorporating a machine controller from the YASKAWA MP2000 series. Servomotor information, including position, speed, motor ID, servo parameters, and error information, is digitally managed to simplify monitoring and maintenance.

Feature 3Enhanced control functions!

• High-precision and high-performance positioning. The position reference, speed reference, and acceleration/deceleration time can be changed in real time during positioning.
• External positioning function using position latch signal: Detects the accurate position when a latch signal is received and adjusts the amount of movement. This is useful for transfer, wrapping, and printing equipment.
• Zero point return: A zero point can be individually set for each of customer's machines.
• Other functions: Interpolation, JOG operation, alarm reset, and other helpful functions.
