: Applicable
*1. These are reference values for setting SERVOPACK parameters. Contact the manufacturer for actual linear
encoder scale pitches.
*2. 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 Linear Servomotor or the maximum
speed of the Linear Encoder (given above).
*3. 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.
*4. Contact Mitutoyo Corporation for details on the Linear Encoders.
*5. This is the model of the Interpolator.
