NOVALUX · Control & drive systems
Variable-frequency drives & drive systems
A variable-frequency drive must suit the motor, the driven load and the operating process. Replacement, adjustments or recurring alarms benefit from an organised review of device data, parameters and process requirements. NOVALUX is your contact for defining the drive task and a possible project scope clearly before changes are made.
Enquire about your project
Who is this service for?
- Operators of pumps, fans or conveyors
- Maintenance teams replacing drives
- Manufacturers investigating unusual drive behaviour
Possible scope of work
- Bring together motor and drive data and existing integration details
- Describe setpoints, feedback and parameter requirements
- Agree controlled functional tests and preservation of the starting state
What you receive
- A defined drive task and compatibility questions
- An agreed parameter overview or backup
- Records of the functions examined and test results
From enquiry to handover
Record the starting data
Nameplates, parameter backups and fault history are gathered. Load characteristics and mechanical limits matter alongside the electrical power rating.
Bound the change
Device replacement, parameter adjustment and changes to machine function are distinguished. Effects on connected controls and operator interfaces are identified.
Prepare the trial run
Work-area release, permitted operating states and stop criteria are agreed before testing. A safe route back to the starting state is considered.
What we need for your quotation
- Motor and drive models
- Available parameter backup and circuit diagram
- Load description and precise fault messages
Frequently asked questions
Is an identical kilowatt rating enough for a replacement?
No. Supply, motor, load, interfaces and installation conditions must also match. Manufacturer requirements and existing protection concepts are considered.
Can speed simply be increased?
Higher speed can affect the mechanical system and process. Permitted limits and consequences must be established before a change; increased throughput is not generally promised.
Will existing parameters be retained?
Backup and possible transfer routes are checked beforehand. Parameter numbers, units or meanings may differ between device families, so an unchecked copy is not sufficient.
