Low
Push the M button on the front panel
of the VFD momentarily. The display
will change to 01___0.0 with the 01
blinking. Momentarily push the up
arrow key to the right of the M key,
the 01 changes to 02. Take note of the
number to the right of the 02. Your
VFD should read 148.X, where X
designates the VFD program version. If
it does not display this value then your
VFD requires reprogramming. To exit
this mode, push and hold the M button
until the display reverts.
Reprogramming a VFD is
a simple operation, but
requires a programming stick
from Tormach.
