PMDX 107 to Huanyang - refusing to work
Hi all,
Well i have spent the past few days trying to get this thing to run and had some wins but over all still not happy...
I have :
2.2kw water cooled spindle
Huanyang HY02D223B
PMDX 107 PWM board
PMDX 137 BOB
the setting I have on my VFD:
PD013 to 8 MASTER RESET <<< DO THIS FIRST
PD005 Max Operating Frequency 400.0
PD004 Base Frequency 400.0
PD003 Main Frequency 25.0
PD001 is set to 1
PD002 is set to 1
PD006 - Intermediate Frequency - 2.5
PD007 Min. Frequency 1.2
PD008 Max. Voltage 220
PD009 - Intermediate Voltage – 13
PD010 is set to 6.5
PD011 - 120
PD041 - 8
PD070 is set to 0
PD141 Rated Motor Voltage 220
PD142 Rated Motor Current 7.5
PD143 - Motor Pole Number - 2
PD144 Rated Motor Revolution 3000
I have the PMDX 107 set up like so:
Dip switches:
1)Off – Normal mode
2)Off – Normal mode
3)Off -For/Rev Setting for relay
4)Off –Charge pump on
5)Off -Fast
6)Off -10v Control signal
Wiring out :
PMDX 107 J1 to VFD J1
Rev/Dri = REV
Fwd/Run = FOR
COM = DMC
Aref = Not connected
Aout = VI
Agnd = ACM
I can run the spindle manually no worries but the issues start when trying to start and set the spindle speed from Mach. I have used a mm to confirm the Pmdx is outputting both a correct pwm voltage to the VFD, the VFD is displaying a a coordinating frequency and the connection between FOR and COM is made.
My three guesses at 1.30am on a Monday morning are that I don't have my ports and pins set up right (unlikely as the pmdx 107 seems to be working as expected), I have screwed up a setting on either the pmdx or vfd and lastly my VFD is broken....
Any other suggestions as to how I can trouble shoot this problem?
not having so much luck...
Well I had an other stab this afternoon and still no luck....
I have set the spindle speed in mach3 to 24000 (max for my spindle) and let it rip. The VFD is reading 23200 and the output from the pmdx is just under 10v.
When I run the calabration the vfd dreads 24000 solid so I am guessing it seems to be an issue with mach.
Any guesses as to the setting I need to change?
"Did you configured in the spindle setup tab the FWD/REV pins?"
no I set it to run under PWM and entered 400 Hz and left the other setting at 5% (unsure what that does but suspect this may be my issue so moved it to 1% and up to 50% with no improvement to my situation)
The settings I used:
Adjusted mach3 pulley to 0-24000
Did the calibration procedure for the pmdx-107
I set up pdoo72 to 400, pd0073 set to 0
Might pop back to the basement and see if setting the pwm setting % to 100 is going to give me the same reading on mach and the VFD
thanks
