SANYO DENKI Develops SANMOTION R 3E Model AC Servo Amplifiers with Built-in Positioning Function

January 7, 2020

SANYO DENKI CO., LTD. has expanded its SANMOTION R 3E Model servo systems lineup with the development of AC servo amplifiers with a built-in positioning function. The lineup comes in a wide variety of capacities and with 100, 200, and 400 V input voltages. These products are ideal for building positioning systems for rotary tables and conveying machines.

Parallel type

Input voltage: 100 VAC   Amplifier capacity: 10, 20, 30 A
Input voltage: 200 VAC   Amplifier capacity: 10, 20, 30, 50, 75, 100, 150, 300, 600 A
Input voltage: 400 VAC   Amplifier capacity: 25, 50, 100, 150, 300, 800 A


1. Efficient Positioning Control

  • A maximum of 254 points can be set.
  • Optimizes rotary table positioning, finding the shortest path to the target destination.
  • Continuous motion, speed at each point, S-curve acceleration/deceleration, and servo gain can be set.

2. Systems Can Be Simplified

Positioning controllers are not necessary, reducing wiring and saving space.

3. Helps Build a Safe and Efficient System

Equipment can be decelerated or stopped immediately when approached by a worker, ensuring workplace safety.
Furthermore, motors can be stopped without cutting power to the equipment, shortening restart time.

4. Selectable Interface Types

Two interface types are available: a parallel type that sends command signals via I/O, and a serial type that sends command signals via RS-485 communication.
