the [SFT] function to one of the intelligent input terminals.

Valid for inputs:
Required settings:
When the terminal [SFT] is turned ON, the data of all the parameters and
functions (except the output frequency, depending on the setting of
locked (prohibited from editing). When the data is locked, the keypad keys
cannot edit inverter parameters. To edit parameters again, turn OFF the [SFT]
terminal input.
To achieve higher motor control performance, the MX2 inverter has the Motor
Cable Length Parameter setting . Normally there is no need to adjust this
parameter, however in case of long motor cable and/or shielded cable, where
there is a comparatively higher earth capacitance, set this parameter higher to
achieve better motor control performance.
Note that the parameter is indicative and no formula to calculate the suitable
value. Normally, longer the motor cable, bigger the set value. Please adjust
depending on your system.
Description
Prevents parameter changes, in
five options, option codes:

Lock (SFT) (Data other than
b031 cannot be changed
when terminal SFT is ON.)

Only FQ (SFT) (Data other
than b031 and the specified
frequency parameter cannot
be changed when terminal
SFT is ON.)

Lock (Data other than b031
cannot be changed.)

Only FQ (Data other than
b031 and the specified
frequency parameter cannot
be changed.)

RUN chg mode (Data other
than parameters changeable
during operation cannot be
changed.)
See Appendix C on page 357 for
the accessible parameters in this
mode.
