* The factory setting will change when the control method is changed. The flux vector factory setting is given.
Field Weakening: d6
User constants for the field weakening command are shown in the following table.
d5-06
Speed/torque
control
switching
timer
Set the delay time from input-
ting the multi-function input
“speed/torque control
change” (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” changes. Always be
sure to allow time for this
process to finish completely.
