Reference mark
Type Customer selected IN-TRAC reference mark, directly embedded into incremental track.
Bi-directional position repeatability.
Selection
Single reference mark selection by selector magnet (A-9653-0143) customer positioned.
L ≤ 100 mm Single reference mark at scale centre
L > 100 mm Reference marks at 50 mm spacing (first reference mark 50 mm from scale end)
Repeatability
Unit of resolution repeatability (bi-directional) across full system rated speed and temperature ranges
Limit switches
Type Magnetic actuators; with dimple triggers Q limit, without dimple triggers P limit
(‘RTLC40 / FASTRACK installation drawing’, page 4)
Trigger point
The limit output is nominally asserted when the readhead limit switch sensor passes the limit magnet
leading edge, but can trigger up to 3 mm before that edge
Mounting
Customer placed at desired locations
Repeatability < 0.1 mm
