Incremental Linear Encoders
: Applicable
*1. You must also use a Yaskawa Serial Converter Unit. The output signal will be multiplied by 8 bits (256 divisions)
or 12 bits (4,096 divisions) in the Serial Converter Unit.
*2. The multiplier (number of divisions) depends on the Linear Encoder. Also, you must write the Servomotor con-
stant file to the Linear Encoder in advance.
*3. 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 speed will be restricted by either the maximum speed of the Linear Servomotor or the maximum
speed of the Linear Encoder (given above).
*4. If you use the origin signals with a Linear Encoder from Renishaw plc, the origin may sometimes be falsely
detected.
If that occurs, use the BID/DIR signal to output the origin signal only in one direction.
*5. These are the models of Serial Converter Units.
*6. This is the model of the Sensor Head with Interpolator.
*7. This is the model of the Interpolator.
*8. Contact your Yaskawa representative.
Note: Confirm detailed specifications, such as the tolerances, dimensions, and operating environment, with the
manufacturer of the Linear Encoder before you use it.
