Rotary Encoders
Absolute Rotary Encoders
The following Absolute Rotary Encoders are for fully-closed control. Do not use it to control the
motor.
*1. The maximum speeds given in the above table are the maximum applicable speeds of the encoders when com-
bined with a Yaskawa SERVOPACK.
The actual s peed will be restricted by either the maximum speed of the Rotary Servomotor or the maximum
speed of the Rotary Encoder (given above).
*2. This is a single-turn absolute encoder.
Note: Confirm detailed specifications, such as the tolerances, dimensions, and operating environment, with the
manufacturer of the Rotary Encoder before you use it.
