How to Read Model Numbers
Note that not all possible combinations of field values may yield valid products. Also, some of the values listed below are for options.
Refer to the Standard Model Number List section for model numbers of standard products.
Servo Amplifier
R 3E Model
EtherCAT interface type
Amplifier capacity: 25 to 800 A
More evolved AC servo amplifiers that provide improved basic performance including
high responsiveness, and are more eco-efficient and easier to use.
With a 62.5
μ
s minimum communication cycle, the high-speed EtherCAT fieldbus
subdivides commands, realizing smoother operation of devices.
