How does the integrated multiturn absolute encoder affect system homing and recovery?

Because absolute position is retained through power cycles, the system does not require a full homing run at startup, improving startup speed and reducing mechanical stress. It also allows safe power cycling with consistent feedback integrity.

What considerations does the 6.5 Nm blocking brake impose on dynamic performance?

The brake adds inertia and mechanical coupling friction—brake release times and wear must be managed in high-cycling systems. Also, the drive control must account for the brake torque when transitioning between hold and motion modes.

How critical is the centering diameter of 110 mm when replacing or retrofitting servos?

Matching the centering or pilot diameter ensures concentricity and alignment, minimizing runout and vibration. If the replacement motor deviates, you risk bearing loads, shaft misalignment, or coupling binding.

What impact does “standard balancing” have on vibration and permissible operating speed?

Standard balancing limits rotor imbalance to a level acceptable for the rated speed, reducing vibration and bearing stress. For higher-speed use or precision applications, one may need a “precision balance” upgrade.

How should one size the drive and cabling given the motor’s digital servo feedback interface?

The drive must support DSF (digital servo feedback) protocol and supply enough current/headroom for peak demands. Feedback and power cables should be shielded and routed separately to avoid EMI degrading the digital encoder signals.
