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

Name LD mode MD mode HD mode Remarks
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

Initial value: 130% Initial value: 145% Initial value: 160%
Switching the drive mode
between LD, MD and HD 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 LD/MD mode, if the
maximum frequency exceeds
120 Hz, the actual output
frequency is internally limited to
120 Hz.

Even switching to the MD/HD mode cannot automatically change the motor rated capacity (P02*), so configure the P02* data to
match the applied motor rating as required.
Note: For 7.5 HP and smaller, when LD mode is selected, the HD mode specification applies.

V/f control with slip compensation inactive
Under this control, the inverter controls a motor with the voltage and frequency according to the V/f pattern specified by function
codes. This control disables all automatically controlled features such as the slip compensation, so no unpredictable output
fluctuation results, enabling stable operation with constant output frequency.
