Frequently Asked Questions
What thermal behavior should be expected from MKD112C-058-GG3-AN under natural-convection cooling and Class-F insulation at 35.6 kW/400 V?
The forced airflow, enclosure temperature and mounting orientation materially affect permissible continuous torque. Its class-F materials tolerate higher winding temperatures but monitoring via the drive’s thermal model remains essential for lifetime.
How does the 70 Nm holding brake interact with the motor’s rated/standstill torques on MKD112C-058-GG3-AN for vertical axes?
The brake is sized for static holding, not for dynamic stopping, while the emergency-stop energy must be handled by the drive and mechanics. Its release current and response times (≈1.29 A, ~97 ms on 112C/058 variants) inform safe-torque-off timing.
What are the servo-tuning implications of the listed 7.63 kg·cm² rotor inertia for load matching and bandwidth?
The low rotor inertia supports higher control bandwidth but increases sensitivity to load-inertia ratio and coupling compliance. Its autoset with frequency-response checks and aims for conservative inertia ratios when compliant transmissions or variable loads are present.
How do the 192 mm flange and 130 mm centering diameter of the MKD112C-058-GG3-AN affect retrofits and IM B5 face mounting?
The DIN-aligned envelope simplifies replacement on legacy frames, its pilot accuracy governs concentricity and vibration to preserve bearing life and alignment.
Does the plain-shaft with seal on MKD112C-058-GG3-AN maintain IP65 when coupled, and what coupling choices are preferred?
The dimensioned sealed coupling and cover is used to preserve the listed IP65 ingress protection. Its backlash-free, torsionally stiff couplings are typically selected to preserve servo stiffness and positioning fidelity.
