A servo motor and drive operate as a matched motion-control system. Similar power ratings do not guarantee compatibility because feedback, commutation, firmware, brake, thermal sensing, and cable requirements must also match.
Confirm the approved combination
Start with the complete motor and drive catalogue numbers. Use the manufacturer’s combination tables to verify supported ratings, firmware, feedback devices, cables, and option modules.
Compare electrical ratings
- Supply voltage and drive output current
- Motor continuous and peak current
- Power, speed, duty cycle, and peak torque
- Regenerative energy and braking resistor needs
- Motor cable length, reactor, and filter requirements
Verify feedback and cables
Encoder or resolver connector shape alone does not prove compatibility. Check protocol, resolution, voltage, pinout, motor identification data, shielding, conductor size, flex rating, and cable length.
Check brake and mechanics
Confirm brake voltage and current, temperature-sensor type, shaft, key, flange, frame, seal, inertia, and load connection. Back up drive parameters before replacement, then commission the axis with suitable limits and safety controls.
Technical enquiry checklist
Provide the motor and drive codes, controller, cables, supply, application, brake, feedback, quantity, and photographs through the US² Automation quote form.
