Build Thread - Acorn DIY 5'x10' CNC Mod
Posted: Mon Dec 12, 2022 6:26 pm
Going to do my best to create a proper build thread (first time posting, long time peruser, thanks folks!)
My CNCPC system specs are in screenshot, along with fresh report.zip, log, several screenshots of current perams, and images of motor and spindle nameplates and VFD wiring.
OUR SYSTEM:
• Huanyang Inverter - HY04D023B (4KW, 0-400HZ, 18A, 220w)
• Chinese Spindle - 300HZ, 18000rpm, 220w, 4KW, 11A)
• NEMA 34 (XY), NEMA 24 (Z) Steppers
• Acorn DIY CNC Control kit

• Windows 10 Home (see photos for system ref)
• UPDATED PHOTOS - Google Photo Album - https://photos.app.goo.gl/gsqK4U8Q5MCWWe2y8
• No Spindle encoder
• Limit switches are all wired as one trip input
•

VFD SETTINGS OF NOTE -UPDATED:
PD001 - 1 (comm port)
PD002 - 1 (comm port - Source of operating frequency)
PD003 - 300 (Main Frequency)
PD004 - 300 (Base Frequency)
PD005 - 300 (Max Frequency - Max RPM of the motor)
PD006 - 2.5 (Intermediate Frequency - Should have no relevance)
PD008 - 220 (Max motor voltage from motor nameplate)
PD009 - 15
PD011 - 000 (Minimum Frequency - Set the lower frequency based on desired minimum RPM)
PD014 - 3 (Acceleration Time)
PD015 - 3 (Deceleration Time)
PD070 - 0 (Analog Input - 0 = 0-10VDC input)
PD072 - 0 (Lowest Analog Frequency)
PD073 - 300 (Highest Analog Frequency)
PD142 - 11 (Motor Nameplate current)
PD143 - 2 (# of motor poles)
PD144 - 3000 (Motor Nameplate RPM
PD176 - 1 (Inverter Frequency Standard)
ISSUES
- no remote/software control of VFD from Acorn CNC12, manual or auto, control only from front panel
- VFD LED For is flashing on startup.
There WAS a weird issue with the VDF prior but we could just press RUN on the front panel and then control from CNC 12 - this no longer works. The only thing different that may have caused a comm issue was that I went through the VFD setting and changed them to what you see above than we lost control of VFD from CNC12.
SOLUTIONS ATTEMPTED AND FAILED:
- replace VFD w exact VFD - same result
- bench tested CNC controller board 0-10v and is ALL GOOD
-
SUSPECTED BLAME:
- missed setting in VFD?
