Frequently Asked Questions
What differentiates the MHD112C-024-PG2-AN servo motor’s feedback architecture from incremental encoders?
The MHD112C-024-PG2-AN uses digital servo feedback with an integrated absolute encoder exceeding 4096 revolutions for enabling true multi-turn position retention without homing. It enhances restart behavior and synchronous multi-axis coordination versus incremental systems.
How does liquid cooling in the MHD112C-024-PG2-AN influence continuous torque density during thermal transients?
Its liquid cooling stabilizes winding temperature for sustaining 38.0 Nm continuous torque at standstill while minimizing thermal derating during overload events. Its housing circuit expedites heat extraction for improving duty cycle in dense multi-axis cells.
Why specify a plain shaft with shaft seal on MHD112C-024-PG2-AN instead of keyed/ splined variants?
The plain, sealed shaft simplifies coupling selection (e.g., clamp or shrink-disc) and maintains ingress protection for IP-rated installations. It also reduces fretting at the hub interface under reversing loads common in servo duty.
How does the holding brake torque (32.0 Nm) on MHD112C-024-PG2-AN affect vertical-axis safety and energy use?
The integrated brake provides static holding capacity during e-stop and power-off for preventing Z-axis back-drive. It reduces reliance on external counterbalance hardware to streamline safety design and lowers standby energy consumption.
What mounting interfaces (centering Ø and flange) aid drop-in replacement for MHD112C-024-PG2-AN?
Its 130 mm centering diameter and 192 mm square flange align with common Indramat/Rexroth frames for easing retrofit into legacy fixtures and adapter plates. It preserves alignment fidelity for precision spindles and tables.
