💖 WJ200_VFD 💖

okay bestie, gather round, because this is the Hitachi wj200 modbus driver — a HAL component that lets your LinuxCNC setup talk to a Hitachi WJ200 variable frequency drive. that's the whole vibe. no cap. ✨

it ships as part of the LinuxCNC docs set, it's a HAL component, and it's filed under manual section 1.

✨ SYNOPSIS ✨

wj200_vfd

that's it. that's the whole invocation. no flags, no args, no drama. she just exists and starts doing her thing. 💅

🌸 PINS 🌸

every pin lives under the wj200-vfd.N. prefix — so wherever you see that little N, that's the placeholder slot in the name. every single one is listed below, no skips, no shortcuts. 🫶

  • wj200-vfd.N.commanded-frequency — float in. the frequency you're telling the vfd to run at. you feed it, she runs it. 💖
  • wj200-vfd.N.reverse — bit in. set it to 1 and the drive goes reverse, set it to 0 and it goes forward. that's the whole deal.
  • wj200-vfd.N.run — bit in. run the vfd. literally just "go".
  • wj200-vfd.N.enable — bit in. 1 enables the vfd. 0 will remote trip the vfd, which disables it. so like, be normal about this one, bestie. 😭
  • wj200-vfd.N.is-running — bit out. 1 when it's running. she's up and she's moving. 🔥
  • wj200-vfd.N.is-at-speed — bit out. 1 when it's running at the assigned frequency. she hit the target, periodt.
  • wj200-vfd.N.is-ready — bit out. 1 when the vfd is ready to run. green light energy. 💚
  • wj200-vfd.N.is-alarm — bit out. 1 when a vfd alarm is set. 💀 something is wrong and she's telling you.
  • wj200-vfd.N.motor-current — float out. output current, in amps.
  • wj200-vfd.N.heatsink-temp — float out. the temperature of the drive heatsink. yes she runs hot, she's working. 🔥
  • wj200-vfd.N.watchdog-out — bit out. alternates between 1 and 0 after every update cycle. feed this into a watchdog component so you can be sure the vfd driver is actually communicating with the vfd properly. it's giving "are you still there??" check-in texts. 📱

🎀 PARAMETERS 🎀

  • wj200-vfd.N.mbslaveaddr — u32 rw. the Modbus slave address. read/write, so you can poke it if you need to.
