Frequently Asked Questions
How does the 3,200 mH winding inductance affect the servo drive’s current regulation and responsiveness?
A high inductance slows current rise time, requiring the drive to compensate via voltage headroom or advanced control loops, which can reduce current responsiveness at high frequencies.
What bearing life expectations apply under typical radial and axial loads?
If kept within permitted radial/axial limits per Rexroth’s “bearing & shaft load” charts, bearing lifetime L10h is rated at ~30,000 hours.
In a high-acceleration application, is the 160 Nm peak torque reliably deliverable momentarily?
Yes, the motor’s peak 160 Nm is a short-duration limit (overdrive region), but sustained use beyond the continuous 57 Nm rating risks thermal overload.
How does the 2,048-period optical encoder (EnDat 2.1) impact position control resolution and closed-loop stability?
The 2,048 periods give fine angular resolution, improving feedback precision and enabling tighter control loops, but the drive must handle encoder latency and jitter.
What consideration should be given to shaft coupling due to the “shaft with keyway” design?
The keyed shaft may introduce imbalance, so the driven assembly should be balanced including the key; modifications are not covered under warranty.
