variable spindle speed PWM o\/p at pin D11 #823<\/strong><\/p>\n

ecncshop commented on 17 Oct 2015
\nIam using GRBL 0.9I version with variable spindle PWM enabled.\u3000\u3000\u3000My doubt is pin D11 : does it output analog 0V to 5V or actually outputs PWM digital pulse train with changing duty cycle?<\/p>\n

ecncshop commented on 19 Oct 2015
\nIf it is PWM pulse train: then what is the frequency? Is it user settable ?
\nThis page says we will get 0V to 5V in pin D11
\nhttps:\/\/github.com\/grbl\/grbl\/wiki\/Connecting-Grbl<\/p>\n

109JB commented on 19 Oct 2015
\nNot sure if grbl uses a different method, but the standard Arduino pwm is 490 Hz.<\/p>\n

The 0v to 5 v is for the pwm equivalent. The output is not true analog. The output is a 0v to 5v square wave and the equivalent analog voltage is dependent on the duty cycle of the output. The pins are 5 v, so 100{c4de8a001cbcae7c382f1dd801287804055307794e3d216dc125c16c479c4f5b} duty cycle is 5 v, 80{c4de8a001cbcae7c382f1dd801287804055307794e3d216dc125c16c479c4f5b} is 4v, 60{c4de8a001cbcae7c382f1dd801287804055307794e3d216dc125c16c479c4f5b} is 3v, etc.<\/p>\n

EliteEng commented on 19 Oct 2015
\nVariable Spindle PWM is “PWM” so yes 5v pulses at different duty cyles to give you an average voltage over time.\u3000\u3000The Mega uses a 16bit timer and the Uno uses an 8 bit timer to generate the pulses.\u3000\u3000The best source of information is the source code<\/strong> itself (spindle_control.c lines 85-96) <\/strong><\/span>which says it has a prescaler of 8 so it should have a frequency of 2MHz.\u3000\u3000If you want to use it as a analog voltage you can add smotthing (capacitors,etc.)
\nif you want to use it as pulses you can change the frequency to suit your needs.<\/p>\n

\nI don’t think 2 MHz is correct. The Arduino clock is 16,000,000 Hz, and the prescaler is 8 as opposed to the default Arduino prescaler of 64, but according to config.h, there are 256 intermediate levels plus the 0{c4de8a001cbcae7c382f1dd801287804055307794e3d216dc125c16c479c4f5b} duty cycle for the speed output (0-256). Also, the frequency would the duration of pin high plus the duration of pin low so you have to divide by 2.<\/p>\n

So,
\n16,000,000 \/ 8 \/ 256 \/ 2 = 3906 Hz <<< GRBL’s PWM frequency\u3000with the default Arduino prescaler of 64, it is
\n16,000,000 \/ 64 \/256 \/2 = 488Hz<\/span><\/strong> <<< Standard arduino PWM frequency<\/p>\n

\n@109JB Yes It has a 2MHz pulse width not frequency
\nThose calculations dont look right.<\/p>\n

fPWM = fCPU \/ (PRESCALER * (1+TOP))
\nfPWM = 16,000,000 \/ (8 * (1+255)) = 7812Hz for the UNO
\nfPWM = 16,000,000 \/ (8 * (1+65535)) = 30Hz for the Mega<\/p>\n

**Note With the default Arduino you will find they use phase correct PWM ( not Fast PWM like GRBL ) so that is why you divide by 2 at the end.<\/p><\/blockquote>\n
