Frequently Asked Questions
Why is the 70 Nm holding-brake capacity significant for vertical or overhauling axes on MKD112C-024-GP3-AN?
The integrated brake supplies static torque to resist gravity or back-driving during power-off or e-stop states. It reduces reliance on external holding devices to enable safe clamping while drives discharge and fieldbus controllers transition to safe states.
How does the 1.01 kg·m² rotor inertia of MKD112C-024-GP3-AN affect inertia matching and structural resonance?
The higher rotor inertia raises permissible load inertia ratios and can attenuate torsional oscillations in compliant drivetrains. It also increases acceleration current demand, so current limits and jerk profiles should be tuned to avoid exciting flexible modes.
How do 325 V rated voltage and 70 A peak influence drive selection and DC-link sizing for MKD112C-024-GP3-AN?
The matching controller must supply the specified peak phase current and operate within the motor’s voltage constant at target speeds. Its controllers are commonly paired in MKD applications to ensure compatible feedback handling and current dynamics.
In what way do 38 Nm continuous stall and 65 Nm max torque guide duty-cycle and thermal modeling for MKD112C-024-GP3-AN?
The continuous stall defines sustained torque at thermal equilibrium, while maximum torque supports short transients. Its motion profiles should follow RMS current limits; accelerate with peaks, then dwell below continuous to maintain winding and magnet temperatures.
How does flange 192 mm on the size-112 frame aid interchangeability across MKD112 variants and machine frames?
The standardized 192 mm square flange eases replacement within size-112 builds and across related winding/brake options. It simplifies mounting plate design and preserves center height when migrating between MKD112C-024-GP3-AN and sibling configurations.
