Frequently Asked Questions
What installation tolerance should I allow for the 130 mm centering flange to avoid misalignment stress?
Even small eccentricities (≥0.05 mm) will induce bending in the shaft and bearing load—target ≤0.02 mm runout to preserve bearing life and torque accuracy. Use precision dowel pins or alignment tools during mount to minimize thermal and machining-induced shift.
How does the digital servo feedback (DSF) influence startup homing and position recovery?
DSF allows the drive to store motor parameters and speed/position information internally so that after a reset or power loss the drive can resume operation without reconfiguring low-level parameters.
How does the plain-shaft with seal compare to a keyed shaft for coupling choice?
A sealed plain shaft allows direct coupling or shrink disk use without keyway stress concentrations, but demands accurate clamping to avoid slippage. Keyed shafts offer easier positive torque transmission but can concentrate stress and require key fit precision.
What cooling limitations or ambient conditions should one consider in long duty cycles?
The motor is designed for ambient ~5–45 °C and uses surface cooling; exceeding those or confining airflow will reduce continuous torque capability.
What is the expected effect of thermal expansion at side A on shaft alignment over wide temperature swings?
Side A deformations can shift up to ~0.6 mm relative to the housing under thermal gradients, so machine design must allow slight axial movement or floating couplings to avoid binding.
