Σ-7-Series Servomotors with Batteryless Absolute Encoders

: 2017/01/19

Yaskawa has released the Σ-7-Series Servomotors with Batteryless Absolute Encoders as an option for rotary servomotors in Σ-7-Series AC Servo Drives.
The encoder does not require a battery, which has simplified wiring and eliminated the need for maintenance.

Advantages of Batteryless Encoder

Troublesome Issues Eliminated

Easy Replacement

Applicable Batteryless Models and Specifications

The lineup includes all Σ-7-Series rotary motors.
You can replace your current motors with no change in performance.

The specifications for batteryless motors are the same as for the standard Σ-7-Series motors.

Surrounding air temperature	：	0°C to 40°C (derating for 40°C to 60°C)
Impact acceleration rate	：	49m/s²
Vibration acceleration rate	：	490m/s²
Motor service life	：	Same as for standard Σ-7-Series motors (Data can be maintained for the length of the motor service life.)

※Use cables for batteryless absolute encoders (same as cables for incremental encoders).
