Spindle encoder calibration

Post by mcbr549 »

Report and video attached
Acorn with Lathe Pro
Lenovo ideapad320 with the latest version of Windows 10 and upgraded ethernet - communicating and responding
Grizzly G9972z lathe
Automation Direct Encoder TRDS 1024VD
Automation Direct GS2 VFD
Automation Direct MicroMax Marathon motor
VFD connected and responding via keypad on VFD
Switched to communicate with Acorn - functioning
Spin FWD DI1 connected to relay 5
Spin REV DI2 connected to relay 4
DCM connected to common on relays 4 and 5
AI Analog input connected to VOUT on Acorn
ACM connected to COM on VOUT bus
Spindle turns with m03 and m04 commands
m05 stops the spindle
When I run the spindlebenchtest program I cannot input the voltage that I read on my VM as it is outside the +/- 10% range allowed.

When conducting the spindle bench test, the VOUT on Acorn is ONLY connected to the meter - NOTHING else. What is your Spindle Max RPM set to? It needs to be set to 3000 for the test.

Confidence is the feeling you have before you fully understand the situation.
I have CDO. It's like OCD, but the letters are where they should be.

That is the "Max spindle (high range)" value on the Control Configuration menu: F1/Setup -> F3/Config -> F1/Control

3000 RPM is a value you put in temporarily, to run the bench test.

Later you will change it to reflect what you have programmed your spindle drive to do, within the limits of what your motor and machine can do.

ALWAYS post a FRESH report when asking for help. F7 Utilities, F7 Create Report
Notebook computers are not recommended.
Spindle bench test is just that a BENCHTEST program. Meant for testing when you do the bench test. As others have said not with a VFD connected to it.
I cover the benchtest and checking the spindle analog output in this video:
