What does A017 mean on an Atlas Copco GA VSD+ air compressor?
Short answer: Drive not healthy — VSD reports a fault or will not come ready. If your Atlas Copco GA VSD+ (Elektronikon with Neos inverter) is showing A017, the controller has logged a specific, documented condition. This page covers what it means, what causes it, what you can safely fix yourself, and when — and why — it takes a technician.
What exactly is the machine telling you?
The Elektronikon flags that the variable-speed drive is reporting an internal fault or is not signalling ready, so the compressor cannot run.
Which machines show this?
Atlas Copco's GA VSD+ range — the newer-generation variable-speed machines with the interior-permanent-magnet motor and Atlas Copco's own Neos inverter, controlled by an Elektronikon with alphanumeric alarm codes such as A017. On these units the controller and drive are tightly integrated, so 'drive not healthy' style codes mean the inverter is refusing to come ready and the compressor simply will not run until it does. Practical tip: a single clean power cycle is a legitimate first move after a site power event, but if the code returns, stop there — the diagnostic trail runs through the drive's internal trip log, which only a technician with the service tools can read.
What causes it?
- Drive reporting an internal fault or failing to signal ready
- Drive cabinet running hot — cooling fans stopped or the room overheated
- A recent site power event (sag or outage) upsetting the drive
Can you fix it yourself?
Sometimes a single clean power cycle clears it; beyond that plus checking cabinet fans and room temperature, this is not an in-house repair.
Step by step — what to try, in order:
- Perform one clean power cycle of the whole unit
- Check that drive-cabinet cooling fans run and the room is not overheated
- Check ambient temperature around the cabinet
- Note any recent site power events (sags, outages) for the technician
When do you need a technician — and why?
Reading the drive's trip log and checking interface cabling and power quality takes service tools — and the drive cabinet's capacitors hold lethal voltage even after power-off.
