The LD/MD-mode inverter is subject to restrictions on the function code data setting range and internal processing
as listed below.

F21*
DC braking
(Braking level)
Setting range: 0 to 80%
Setting range:
0 to 100%
In the LD/MD mode, a
value out of the range, if
specified, automatically
changes to the maximum
value allowable in the LD
mode.
F26

Setting range:
0.75 to 16 kHz
(0.5 to 30 HP)
0.75 to 10 kHz
(40 to 100 HP)
0.75 to 6 kHz
(125 to 900 HP)
0.75 to 4 kHz

Initial value:
130%
Initial value:
145%
Initial value: 160%
Switching the drive mode
with function code F80
automatically initializes the
F44 data to the value
specified at left.

Setting range: 25 to 500 Hz
Upper limit: 120 Hz
Setting range:
25 to 500 Hz
Upper limit:
500 Hz
In the variable/constant
torque mode, if the
maximum frequency
exceeds 120 Hz, the
actual output frequency is
internally limited to 120 Hz.

Even switching to the Variable/Constant Torque mode cannot automatically change the motor rated capacity
(P02*), so configure the P02* data to match the applied motor rating as required.
