Set the delay time from input-
ting the multi-function input
"speed/torque control
change" signal (from On to
OFF or OFF to ON) until the
control is actually changed, in
ms units.
This function is enabled when
the multi-function input
"speed/torque control
change" is set. In the speed/
torque control switching
timer, the analog inputs hold
the values of when the
"speed/torque control
change" signal changes.
Always be sure to allow time
for this process to finish com-
pletely.
0: Disabled
1: Enabled
Usually, use a setting of 1
(enabled).
Be sure to enable this setting
when rotating the motor in
the same direction as the
speed limit (winding opera-
tion).

Set the Inverter output volt-
age when the field weakening
command is input.
It is enabled when the field
weakening command is set
for a multi-function input.
Set the level as a percentage
taking the voltage set in the
V/f pattern as 100%.
Set the lower limit in hertz of
the frequency range where
field control is valid.
The field weakening com-
mand is valid only at frequen-
cies above this setting and
only when the speed is in
agreement with the current
speed reference.
