Learning outcomes
- Explain the key principles of vsd parameters and commissioning.
- Carry out a structured practical check or configuration task.
- Recognise common faults, risks and evidence needed for diagnosis.
Module 5 · Lesson 2
VSD parameters and commissioning
Commission a VSD using motor data, control mode, ramps, limits, I/O and protective settings.
Before you begin
Drive keypad/software, motor nameplate and commissioning checklist.
Safety: Use site procedures, approved test equipment and competent supervision. Never bypass a protection or interlock without formal control.
Step-by-step learning
- Enter exact motor nameplate data and perform the approved identification routine.
- Set minimum/maximum frequency, acceleration, deceleration and current limits.
- Configure local/remote control, digital inputs, analogue scaling and relay outputs.
- Test stop modes, fault behaviour and restoration after power loss.
Ian's practical tips:
- Save a parameter backup before and after commissioning.
- A drive should never unexpectedly restart unless the risk assessment and design explicitly allow it.
Fault-finding questions
- What should be happening, and what evidence proves it?
- Where is the last known correct signal, voltage, state or process condition?
- What changed immediately before the fault?
- Can the system be divided into smaller testable sections?
Practical activity
Create a one-page test record for this lesson. Include expected values, measured results, equipment used, risks controlled, defects found and the final proven condition.
