Linear Encoder Speed Limit
The linear encoder has speed limits relative to encoder resolution; these limits are listed below:
Encoder Resolution
Maximum Velocity (2)
Required Post Quadrature Input
Bandwidth (1)
1 micron
3 meters/second
6.7 Mhz
0.5 micron
1.5 meters/second
6.7 Mhz
0.1 micron
0.3 meters/second
10 Mhz
(1)
This is the bandwidth frequency that the amplifier or servo control input should have to operate properly with the encoder output at
maximum speeds. This frequency is post-quadrature, to determine pre-quadrature divide above values by 4. Above frequencies include a
safety factor for encoder tolerances and line loses.
(2)
Maximum encoder speed may exceed maximum speed of positioner
– See Section 2.51, General Table Specifications, for maximum
screw speed.
