The brake-equipped complete motor can differ from the listed basic motor weight. Confirm final shipping weight and dimensions before freight calculation.
Engineering Notes
The M1 encoder supplies multiturn absolute feedback through Hiperface. The keyed shaft supports positive torque transmission, while brake option 2 provides stationary load holding after controlled axis stopping. The brake is not intended as a service brake or personnel-protection device.
This configuration may be suitable for heavy feed axes, handling equipment, winding systems, printing machinery and high-inertia machine modules. Motor-drive sizing must consider the 48 Nm continuous standstill torque, 187 Nm peak torque, load inertia and thermal duty cycle.
Replacement Checklist
- Confirm R911312762 and the complete model.
- Verify M1 Hiperface feedback compatibility.
- Check B-side cable routing.
- Confirm keyed-shaft dimensions and coupling.
- Verify brake option 2 voltage, wiring and holding requirement.
- Confirm the drive parameter set for MSK100D-0300.
