Choose a drive and motor that fit the application
A positioning axis, conveyor and variable-speed pump place different demands on a drive. Start with what the machine needs to do: the load it moves, the speed required, the operating cycle and the level of positioning control.
For a new requirement or proposed replacement, PMI can review the equipment combination and its suitability for the application. Relevant details include:
- Supply voltage, drive current and motor ratings.
- Continuous and peak torque, operating speed and duty.
- Encoder or other feedback, motor brake and associated cabling.
- Mounting dimensions, shaft arrangement and available cabinet space.
- Controller interface, command signals and required operating mode.
Bring the motor and drive details together so the proposed solution can be assessed as a working system.
Match the control interface before selecting hardware
The full model designation matters. Inovance’s SV660N servo family uses EtherCAT, while SV660F uses PROFINET. Those different interfaces affect how the drive connects to the controller and how the application is configured.
For an EtherCAT installation, the device description, communication settings and control mode form part of the integration review. Existing PLC or motion control projects, parameter backups and wiring information help establish what can be retained and what needs attention.
PMI’s industrial automation support provides the wider context for these discussions.
Investigate drive alarms at the machine
Tell us what happens when the fault appears. Useful examples include:
- The drive powers up but the servo will not enable.
- The motor oscillates, runs unevenly or struggles to hold position.
- A following error appears during a particular movement.
- An EtherCAT device fails to reach its operational state.
- An inverter trips during acceleration or deceleration.
- A replacement drive starts normally but the machine will not move.
The alarm is one piece of evidence. Drive status, parameters, motor feedback, communication and the driven mechanism all help establish the cause.
Send the exact alarm text or code, when it occurs and any recent changes. This helps focus the investigation and identify the appropriate next step.
Plan replacement through to commissioning
A drive replacement can involve parameter transfer, controller configuration, feedback settings and checks on the machine’s movement.
Discuss the component and engineering requirements together. PMI can assess the proposed replacement and agree whether sourcing, installation, setup or commissioning support is needed for the identified equipment.
For parts, we confirm the full item designation, suitability, condition and availability against the actual enquiry.

Inovance support questions
Can I discuss Inovance equipment for a new project?
Yes. Explain the machine function, existing or proposed controller, motor requirements and intended operating cycle. We can review the requirement and discuss an appropriate component or engineering scope.
Can a servo motor be matched to a drive by power rating alone?
The assessment also needs feedback compatibility, current, speed, torque, voltage and control requirements. Brake arrangements, cables and mechanical fit can affect the combination too.
What should I send about an existing drive fault?
Email clear photographs of the drive and motor labels, the exact alarm and a description of the machine’s behaviour. Tell us which parameter backups and relevant drawings are available, and describe recent replacements or configuration changes.
Start with the equipment and the outcome you need
Whether you need to investigate a fault, identify a component or plan an upgrade, send PMI the equipment details, application and site location.
