Stop position accuracy ±100 mm for position, ±2° for rotation
-with the HAPS option ±10 mm for position, ±0.5° for rotation
Traversable step, max: LD-60 LD-60: 15 mm (0.6 inch)
LD-90: 10 mm (0.4 inch)
NOTE:A speed of 250 -300 mm/s for the LD-60 and 250 mm/s for
the LD-90 is required for these steps. Faster or frequent driving over
such steps or gaps will shorten the lifespan of the drivetrain com-
ponents. Lower speeds may not traverse the step. Steps should
have smooth, rounded profiles.
