Level
Sets the Drive output voltage
when the multi-function input
"field weakening command"
is input (H1-xx = 63). Sets as
a percentage taking the
voltage set in the V/f pattern
as 100%.

Frequency
Sets the lower limit (in Hz) of
the frequency range where
field weakening control is
valid. The field weakening
command is valid only at
frequencies above this setting
and only when output
frequency is in agreement
with the current output
frequency (speed agree).

Constant
Sets the A-phase-R time
constant in relation to the
motor secondary circuit time
constant by the amount of
increase.
Note: A-phase-R Time
Constant = (Secondary
Circuit Time Constant)
x (d6-05).
When d6-05 = 0, then
A-phase-R is inactive.
When d6-05 = 0, it
becomes the lower limit
for 200ms internal to the
drive.
