Appendix 3 Compatibility with the communications func-
tion
of the VF-S9
To provide consistency in communications procedures, the communications function of the VF-S11
series of inverters has been designed based on the protocols used for the Toshiba VF-S9 series of
inverters. With regard to compatibility, however, VF-S9 users should check the items described be-
low before using the communications function of their inverters.

low before using the communications function of their inverters.
■ To VF-S9 inverter users:
Some parameters of the VF-S9 are different from those of the VF-S11 in function or adjustment
range (upper and lower limits), even though they have the same title or the same communication
number. So, when accessing a parameter, consult the VF- S9 inverter’s instruction manual to see if
the parameter is identical to the corresponding parameter of the VF-S11. If the parameter differs,
modify the computer program to suit your inverter. To avoid hazards, never copy parameters from
one model of inverter to another.

■ Comparison of communication-related items
The table below gives a comparison of communication-related items to be kept in mind when re-
placing VF-S9 inverters with VF-S11 inverters or when connecting VF-S9 inverters and VF-S11 in-
verters to the same network. It does not cover any items common to the VF-S9 and VF-S11 series of
inverters.

Notice
♦ Do not use communications programs written for another series of inverters.
Even though parameters have the same title and the same communication number, they may be different
in function. When using a parameter, always check its specifications in the instruction manual for your
inverter. If the specifications of the parameter differ, modify the computer program to suit your inverter.
