Example
The voltage - frequency converter
test program displays two
numbers that represent internal
conversion values used in the
electronic control board, and
must be between
40.0 ÷ 45.0
(See table T8.2).
If the value of both or one of the
two pick-ups is 0, check the
connection and change the pick-
up, or both, if necessary.

program.
Il Value A refers to pick-up A VFC, while value B refers to pick-up B VFC. The displayed values must be stable (if no one touches or
bumps into the machine) and must be between the tolerance range stated in table T8.2. If the machine is touched or bumped into,
both VFC channels will vary and re-stabilise when the mechanical interference stops.
