1.2.2 Applicable Linear Encoder
An incremental linear encoder to be used for the FANUC Linear
Motor L
iS series must satisfy the following specifications:
- The output from the linear encoder is an analog signal at 1 Vp-p.
- A reference mark signal (Z-phase signal or another signal) is
output from one device or the linear encoder is distance coded.
If reference mark signals are output from two or more devices, an
alarm may occur when the same signal is detected for the second time.
The following table lists typical incremental linear encoders that can
currently be combined with the FANUC Linear Motor L
iS series.

1 Optodyne LDS is Laser Doppler encoder.
2 The "resolution" in the above table indicates the value internally multiplied by the
position detection circuit. The last digit is rounded off.
3 An incremental linear encorder must output only one reference mark signal. Before
ordering a linear encoder, designate this requirement to the relevant linear encoder
manufacturer.
4 Linear encoder manufacturers are responsible for the specifications, performance,
guarantee, and other items of their linear encoders. For details, contact the relevant
manufacturer.
