SANYO DENKI Develops 400 VAC, 150 and 300 A Servo Amplifiers
That Can Predict Failures
Detects danger and stops motors immediately
April 10, 2018
SANYO DENKI CO., LTD. has developed new AC servo amplifiers, expanding the lineup of the SANMOTION R 3E Model series.
This servo amplifier has been equipped with a function for predicting equipment failures using the operating data of the amplifier and motor.
It can operate 5.5 to 30 kW motors smoothly, making it ideal for equipment such as machine tools and injection molding machines.

Features
1. Innovative Maintenance
This servo amplifier is equipped with various functions: holding brake deterioration diagnosis,(1) power consumption monitoring of regenerative resistors, monitoring of encoder communication quality, and a relay counter.
These enable users to predict equipment failures, leading to innovations in maintenance.
2. Safe and Efficient System
Equipment can be decelerated or stopped immediately when a worker approaches it, ensuring the safety of the workplace.
Furthermore, motors can be stopped with power still available to the equipment, shortening the reboot time.
3. Smooth Motion
In addition to regular analog/pulse models, models with high-speed EtherCAT fieldbus are also available.
The EtherCAT communication cycle is 1/2(3) that of our conventional model,(2) achieving even smoother motion of the embedded equipment.
4. Energy-Saving
The power consumption has been reduced by up to 20%, contributing to saving energy.(4)
(1) Patent pending
(2) Comparison with the SANMOTION R ADVANCED MODEL EtherCAT interface type.
(3) The shortest communication cycle: 62.5 μs (125 μs for the above product in (2))
(4) Comparison with our conventional servo amplifier RS1C15A.
