Application and selection overview
Support for variable frequency drives, servo systems, motors and motion control components. Share the existing model, motor data and application requirements so our team can check compatibility and availability.
Key parameters to confirm
| Item | Information to provide |
|---|---|
| Load and motion | Load inertia, torque, speed, positioning accuracy, travel, acceleration and cycle time. |
| Motor and feedback | Power, voltage, current, continuous/peak torque, encoder type and brake. |
| Drive | Continuous/peak current, overload, supply, braking, regeneration, filtering and cooling. |
| Control and network | Pulse, analog, EtherCAT, PROFINET, EtherNet/IP or proprietary fieldbus. |
| Mechanical and safety | Flange, shaft, key, gearbox, orientation, STO and machine-safety requirements. |
RFQ checklist
- Provide full motor, drive, encoder and gearbox models.
- Send the motion profile, load inertia, transmission ratio and mounting drawing.
- State whether parameter files, software, network configuration and homing method are available.
- List cable lengths, connectors, braking resistors, filters and spares.
Common mistakes and risks
- Comparing power only and ignoring peak torque, inertia ratio and drive current.
- Mismatching motor and encoder versions or omitting feedback cables and connectors.
- Replacing an obsolete servo without assessing mounting, parameters, bus and safety changes.
Frequently asked questions
Must motor and drive be the same brand?
Most servo systems use manufacturer-specific feedback and parameters and should follow the compatibility table. Standard induction motors with VFDs are a different case.
Can only the drive be replaced on an old servo?
Motor code, feedback, firmware, fieldbus, power and parameter conversion all require confirmation.
When is a braking resistor or regenerative unit needed?
It depends on deceleration, inertia, descending load, cycle rate and bus energy and should be calculated using manufacturer guidance.
