SYNOPSIS

wj200_vfd

PINS

wj200-vfd.N.commanded-frequency real in

Frequency of vfd (scaled to RPM)

wj200-vfd.N.motor-frequency real out

Motor’s actual frequency (scaled to RPM)

wj200-vfd.N.motor-reverse bool out

1 when actually turning in reverse

wj200-vfd.N.reverse bool in

1 when reverse 0 when forward

wj200-vfd.N.run bool in

run the vfd

wj200-vfd.N.enable bool in

1 to enable the vfd. 0 will remote trip the vfd, thereby disabling it.

wj200-vfd.N.is-running bool out

1 when running

wj200-vfd.N.is-at-speed bool out

1 when running at assigned frequency

wj200-vfd.N.is-stopped bool out

1 when stopped

wj200-vfd.N.is-ready bool out

1 when vfd is ready to run

wj200-vfd.N.is-alarm bool out

1 when vfd alarm is set

wj200-vfd.N.motor-current real out

Output current in amps

wj200-vfd.N.heatsink-temp real out

Temperature of drive heatsink

wj200-vfd.N.watchdog-out bool out

Alternates between 1 and 0 after every update cycle. Feed into a watchdog component to ensure vfd driver is communicating with the vfd properly.

PARAMETERS

wj200-vfd.N.mbslaveaddr ui32 rw

Modbus slave address

wj200-vfd.N.frequency-scale real rw (default: 1)
