Neale,
thank You once more for directions. Much appreciated.
with your help I got spindle to run :)
Here is my wiring at he moment:
Output 4 and Analog Output are activated together (PIN 16)
Output 3 are set as Dir in UCCNC software, activated with PIN 14.
I have managed to connect and use Output #3 as Direction signal. Settings in UCCNC:
Here is short video from the test:
However I have few problems so far:
1. When spindle is activated with "forward" signal (M3S24000), spindle goes up to speed and handles speeds down to approx M3S1000). The problem is with reverse - it goes up to speed all good with M4S24000, but once speed set to 12000 spindle stops. It is the same if I would try to start spindle with lower speed than 15000 - spindle just wont start. Sometimes this happens with FWD too.
I have tried search if there anything to configure in VFD - but no luck.
2. From time to time when reverse direction (M4) is given through UCCNC, spindle starts to rotate in FWD direction. Once stopped and reverse command repeated rotation direction is correct.
3. Once M3 command is given, spindle is getting up to speed and sometimes even at acceleration process UC300 giving message on screen that motion controller has been disconnected and everything stops. It is not possible to use spindle at the time as UC300 gets disconnected at any time once spindle rotation is activated.
I tried to play with SFr [Switching freq.] and at 16hz was total nightmare as the UC300 gets disconnected once spindle is started. Currently I left setting at 2hz as this option lets to get spindle up to full speed, but shortly UC300 gets disconnected...
Current settings for AltiVar320:
VFD set to SINK mode
CFG [Macro configuration] - [Gen. Use] (GEn): General use
tCC [2/3 wire control] - set to 2C
Ctt [Motor control type] - set to Std
ACC [Acceleration] - set to 5.0
dEC [Deceleration] - set to 3.0
bFr [Standard mot. freq] - set to 50
nPr [Rated motor power] - set to 0.80
UnS [Rated motor volt.] - set to 220
nCr [Rated mot. current] - set to 5.0
FrS [Rated motor freq.] - set to 400
nSP [Rated motor speed] - set to 24.00
tFr [Max frequency] - set to 400
LSP [Low speed] - set to 0
HSP [High speed] - set to 400
SFr [Switching freq.] - set to 2
FLU [Motor fluxing] - set to FnO [no]
nrd [Noise reduction] - set to YES
UiL1 [AI1 min value] - 0v
UiH1 [AI1 max value] - 4.5v
I will try do to a factory settings reset and configure once again, but I would appreciate any input on these issues.
Thank You
TM
