๐Ÿ’– PI500_VFD(1) โ€” HAL Component ๐Ÿ’–

okay bestie, sit down, hydrate, and let me tell you about pi500_vfd, aka the Powtran PI500 Modbus driver โœจ she's a HAL component, she talks Modbus, she babysits your VFD, and honestly? she ate. ๐Ÿซถ


๐ŸŒธ NAME ๐ŸŒธ

pi500_vfd โ€” the Powtran PI500 Modbus driver, no cap ๐Ÿ’…


โœจ SYNOPSIS โœจ

Just run her, bestie, there's nothing to pass in:

pi500_vfd

๐ŸŽ€ PINS ๐ŸŽ€

Every pin lives under the pi500-vfd.N. namespace, where N is the instance number. Here's the whole squad, one by one, no skipping:

  • pi500-vfd.N.commanded-frequency (float, in) โ€” the frequency you want the vfd to do. literally just tell her the vibe ๐ŸŒˆ
  • pi500-vfd.N.run (bit, in) โ€” run the vfd. go girl, go ๐Ÿƒโ€โ™€๏ธ
  • pi500-vfd.N.enable (bit, in) โ€” set it to 1 to enable the vfd. set it to 0 and it will remote trip the vfd, thereby disabling it. so like, 0 is not "gentle pause", 0 is the eject button ๐Ÿ’€
  • pi500-vfd.N.is-running (bit, out) โ€” 1 when running ๐Ÿ”ฅ
  • pi500-vfd.N.is-at-speed (bit, out) โ€” 1 when running at assigned frequency. she hit the target, main character energy ๐Ÿ‘‘
  • pi500-vfd.N.is-ready (bit, out) โ€” 1 when vfd is ready to run ๐Ÿ™‹โ€โ™€๏ธ
  • pi500-vfd.N.is-alarm (bit, out) โ€” 1 when vfd alarm is set ๐Ÿšจ not iconic, but useful to know
  • pi500-vfd.N.motor-current (float, out) โ€” output current, in amps โšก
  • pi500-vfd.N.heatsink-temp (float, out) โ€” temperature of the drive heatsink ๐ŸŒก๏ธ she's warm, she's glowing
  • pi500-vfd.N.watchdog-out (bit, out) โ€” alternates between 1 and 0 after every update cycle. feed this into a watchdog component to make sure the vfd driver is actually communicating with the vfd properly. it's giving "still alive, bestie?" ๐Ÿถโœจ

๐ŸŒŸ PARAMETERS ๐ŸŒŸ
