Frequently Asked Questions
What positioning performance does the DSF encoder enable in practice?
DSF provides ~2.097 million counts/rev with ±0.5 arc-min system accuracy, supporting tight contouring and smooth interpolation. The multiturn absolute version tracks ~4096 rotor turns for true absolute startups.
Plain shaft or keyway—what’s better for belt/pinion loads and reversals?
Rexroth recommends plain shafts with friction-locked couplings for backlash-free torque transfer and superior concentricity. Keyways are form-fit but can degrade runout and concentrate stress under frequent reversals.
How should I check bearing loading for pulleys or gears?
Permissible radial load depends on average speed and distance from the bearing shoulder; bearing life is based on L10h = (Fradial/Fload)³ with a 30,000 h target. Axial limits are defined separately; prefer plain shafts for high radial forces.
How should the holding (blocking) brake be applied on vertical axes?
Use it as a holding/safety brake; size it so the static load (after gearing) is within the brake’s rated holding torque and wire it per the specified 24 V DC ±10%. Observe the documented release/clamp times and the drive’s enable sequence.
What connector orientations and cabling choices simplify tight enclosures?
You can order the power connector toward side A/B or left/right and use straight or elbow feedback connectors to suit cable egress. Choose orientation at order time to avoid clearance issues.
