Functions for parameter change-over

The inverter supports several parameter sets. The parameter set can be selected by means of
the "Select parameter set (bit 0)" and "Select parameter set (bit 1)" functions.
DANGER!
Changed parameter settings can become effective immediately depending on the activating
method set in 0x4046 (P755.00).
The possible consequence is an unexpected response of the motor shaft while the inverter is
enabled.
▶ If possible, only carry out parameter changes while the inverter is disabled.
▶ Certain device commands or settings which might cause a critical state of the drive behav-
iour can generally only be carried our when the inverter is inhibited.
Details
The "parameter change-over" function provides a change-over between four sets with differ-
ent parameter values for up to 32 freely selectable parameters. For details on the compilation
of the parameters and setting of the value sets, see the chapter
^ 464
A value set is selected in a binary-coded fashion via the triggers assigned to the two Select
parameter set (bit 0)" and " Select parameter set (bit 1)" functions in compliance with the fol-
lowing truth table:
Select parameter set (bit 1)
0x2631:042 (P400.42)
FALSE
FALSE
TRUE
TRUE
Change-over is effected depending on the activation method selected in
when a state change of the selection inputs takes place or via the trigger assigned to the
"Load parameter set" function.

Info
Assignment of a trigger for the "Load parameter set" function.
Trigger = FALSE-TRUE edge: parameter change-over to the value set
selected via "Select parameter set (bit 0)" and "Select parameter set (bit
1)".
Trigger = FALSE: no action.
Notes:
• The activation method for the "Parameter change-over" function can
be selected in 0x4046 (P755.00).
Assignment of a trigger for the "Select parameter set (bit 0)" function.
Selection bit with the valency 2
Trigger = FALSE: selection bit = "0".
Trigger = TRUE: selection bit = "1".
Assignment of a trigger for the "Select parameter set (bit 1)" function.
Selection bit with the valency 2
Trigger = FALSE: selection bit = "0".
Trigger = TRUE: selection bit = "1".
