About the change of parameter settings
By the VF-AS1/PS1’s default, the inverter is set with parameters to the mode in which
it controls the operation of the machine via a terminal board. Moreover, the inverter is
set so that the switching between forward run and reverse run cannot be performed
using its operation panel.
By the VF-MB1’s default, the inverter is set so that the switching between forward run
and reverse run cannot be performed using its operation panel.
To operate the inverter using this unit, parameter settings need to be changed, as
described below.

This change of parameter settings makes it possible to start operation using the
[RUN] key, to stop operation using the [STOP/RESET] key, and to switch between
forward run and reverse run using the [FWD/REV] key.
Furthermore, it allows you to set an operation frequency using the control dial.
Refer to “5.1 Setting a panel operation frequency.”
