In the process of installing the EX controller to a non-Avid CNC machine. I have the 1x14 conductor cable and the 1x14 pin panel mount. Is there an adapter or method to convert the 1x14 pin panel mount to RS485 for the Huanyang VFD?
The Acorn itself doesn’t do RS485, your best bet is to re-configure the VFD to accept 0-10 volt analog for speed control.
Also, do you know we publish our schematics: Schematics - EX Controller Technical Manual
Right. Figured out the Acorn does not do RS485. Started to map the 1x14 schematic to the Huanyang. Figured out most except for ConnectorPin #1 and #2. #1 is Fault Ground. #2 is Fault Signal. What are the conditions to trigger fault ground and fault signal? Thanks.
Look at using parameter PD050 / 51 / 52 set to 3 for fault condition with one of the outputs. The two pins should be closed under normal running condition.
You’d want normally closed and for the output to open in a fault condition.
I don’t believe the Huyang has a fault signal, and you’d set your Acorn to ignore VFD faults in the config.
If you don’t have a vfd fault you might need to flip a dip switch in the EX controller. I had to do this on the EX with servos. Don’t know if it applies to Nema EX.
I didn’t have to flip a switch, and I’m on servos.
