Здравствуйте. Какой частотник подключили к новому шпинделю? Они, насколько я знаю, на выход дают 3 фазы по 220 вольт. А у Вас требуемое 3х36 в. gnch 09.03.2019 16:37:41
Привет! Частотник входит в комплект шпинделя. Называется Windward BLDC-DZZ. Его входное и выходное напряжение 36В. Alex 09.03.2019 18:16:55
Are you able to control speed and off and on, via GBRL controller software? If so can you tell me how you connect the Windward BLDC-DZZ. to the GBRL board. Regards troy 10.08.2020 9:00:15
Hi! 1. On / off control: manual. See pin 10 on the diagram. 2. PWM: using the "CNC control" connector (see pins 2 and 7). Pin 2 is connected to pin "S" of the three-pin laser connector (through a 0.1K resistor). Alex 11.08.2020 11:11:51
Hi Alex thanks for the info. I will buy this spindle soon but on the aliexpress they have 2 options for the CNC cable. 1 Signal Start and Stop 2 Signal 0-10V They also say I need extra converter to have 0-5v I do not fully understand and the seller don't know anything about the spindle. I would like to be able to control the spindle speed and start stop via software. If I connect the spindle to the pwn conector on the GRBL board will I be able control the speed and strat stop via software? Do I need to buy a 0-10v to 0-5v converter? Spindle link Regards troy 13.08.2020 2:33:06
Hi Troy! You don't need any additional converters. The solution I described above, allows you to control the start / stop of the spindle and its speed. The Arduino shield can output a "0%" PWM signal. In this case, the spindle will be turned off. If the Arduino shield gives a PWM signal "100%", then the spindle will run at maximum speed (24000 rpm).

Ok, thanks troy 15.08.2020 23:53:52
Hi Alex, I need your help. I connect the BLDC-DZZ Pwm pin to the Pwm pin on the GRBL board, but the spindle don't start from CNC software. Can you look at my photos and let me know if I have the correct switch settings on the BLDC-DZZ. Thanks troy 04.09.2020 18:38:49
Hi, Troy! Fit the spindle "pre-enable" switch in circuit 10 on the right of the diagram. Switch it ON before starting the control program. Or supply + 5V to pin # 3 (green) of the control connector. Alex 04.09.2020 21:06:19
Hi Alex thanks for the info, I did as you said but still the BLDC-DZZ won't start via PWM. The PWM signal is 100% coming from the grbl board but it seems the BLDC-DZZ CNC control port pin 2 and pin 7 is not communicating with the GRBL PWM. Do you have any ideas I could try to get the PWM working ? Thanks troy 05.09.2020 15:26:20
