Product Specifications for Ultra-High Precision Positioning
Absolute Type Linear Encoder

Ultimate Running Performance❶ Return to Origin Not Required - Equipment Start-Up Time Reduced

The TX table uses IKO C-Lube Linear Roller

Absolute Type Linear Encoders measure the absolute position immediately afterpower is supplied, eliminating the need for a homing operation after it is started
or after an emergency stop. They also eliminate the need for pre-origin sensors
required with incremental type linear encoders. This means choosing IKO Super

Way X linear motion rolling guide which
provides the highest level of operating
performance to achieve ultimate running
accuracy.

Precision Positioning Table TX with an absolute type linear encoder can❷ Achieves Both High Resolution and High Speed Travel
Servo systems equipped with incremental type linear encoders have restrictions
on the maximum input frequency on the receiver side, so generally as resolution
increases the maximum speed decreases.
On the other hand, absolute type linear encoders use serial communication andmeasure the position according to the request, therefore the maximum speed
doesn’t decrease even at high resolutions. At a resolution of 0.05 μm and ballscrew lead of 10 mm, the TX maximum speed for incremental types is 200 mm/s,

Attitude accuracy sec

drastically reduce equipment start-up time.

Absolute types, like IKO TX, are ideal for applications requiring both highresolution and high speed travel.
