Hi

I messed up the settings on my LY4030 cnc mil.
https://www.aliexpress.com/item/3294...27424c4dijQoc0

Now i get error: Er. 04

I cant find the manual anywhere and ive opened the control unit and cant find the name of the VFD.
Only number i find on the board is: HJ07ADB485

Does anyone have a manual or any bright ideas.

The first 16 settings are:
Pr.000 = 1
Pr.001 = 0
Pr.002 = 0
Pr.003 = 400 = 50-400 Max Hz
Pr.004 = 400 = 50-400
Pr.005 = 220 = 5-255
Pr.006 = 110 = 1-120
Pr.007 = 15 = 0.5-250
Pr.008 = 20 = 0.1-120
Pr.009 = 120 = 1-120
Pr.010 = 0 = 0-1
Pr.011 = 0 = 0-7
Pr.012 = 75 = 0-9999
Pr.013 = 47 = 0-60
Pr.014 = 0.2 = 0.01-99.99
Pr.015 = 15 = 0.1-100
Pr.016 = 0 = 0-1

First value is the value and second is the range of the parameter.
