Frequently Asked Questions
What does the 113 V/1000 rpm voltage constant imply for drive selection on MSK076C-0300-NN-M1-UP0-NNNN?
The back-EMF scales with speed (~113 V per krpm), so the DC bus and inverter must allow commanded speed without saturation. Its data is referenced to ~750 V DC link conditions in catalog tables for guiding bus-voltage and field-weakening margins.
Why specify an optical encoder with 128 signal periods and a 240° rotatable connector?
The 128-period Hiperface option offers clean sine-cosine feedback with low signal bandwidth demands and wide max-speed capability, while multi-turn variants (M1) add absolute turns counting. Its 240° rotatable connector simplifies cable exit orientation and routing in dense machines.
How do 1.84 Nm/A torque constant and current limits translate to acceleration planning for MSK076C-0300-NN-M1-UP0-NNNN?
The torque ≈ Kt × I; with value of Kt≈1.84 Nm/A identifies motor torque and load inertia determines achievable angular acceleration (α = T/J).
What are the control implications of 12.6 mH phase inductance and 1.85 Ω resistance in this motor?
The inductance shapes current-loop bandwidth and switching-frequency losses, while its resistance sets copper loss (I²R) and thermal rise at standstill torque. Its drive current controller should be tuned with these parameters and thermal model to respect the 60-minute thermal constant.
What environmental protection and mechanical options exist in the MSK line relevant to this product code?
The MSK motors are designed to IP65, with options for shaft keyway, reduced runout and brake variants, while its electrical and encoder connections are standardized across sizes. It simplifies interchange and spares strategies across machine families.
