Besides the optional add-on cassettes, such the board options as shown below are prepared for
the inverter VF-A7.
Table of board options
Option name Function, purpose Model Remarks
VEC002Z
(For complementary / open
collector type encoder)
PG feedback
board
Since this option is compatible to
vector option unit, it can be used
for speed control and torque
control by the PG feedback
function.
VEC003Z
(For line driver type encoder)
Cannot be
used together
with any
optional add-on
cassettes.
