156 A AXIS Z CH MISSING
Getting this alarm when trying to home my A axis. Machine is a 2000 VF-3, indexer is an HRT-210.
The alarm description says it can be a bad cable, bad encoder, incorrect parameters or loose wires. The indexer runs fine when hooked up to our control box on another machine. This is the first time this machine and indexer have ever been connected. The indexer is a brush style and the machine is set up for a brush style indexer. I spent about an hour on the phone with HAAS going through the parameters and everything is what they say it should be.
The indexer starts to home, moves about an inch and then alarms.
Due to the fact that the indexer runs fine when hooked up to the control box I assume the encoder and cable are fine. They were both replaced about 1.5 years ago. Haas verified my parameters so I am assuming that is not the issue either. I have looked for any loose wires or bad connections but see nothing obvious but will be honest I am not 100% on where I need to focus my search for loose connections.
Any ideas?
