frequency
When A and B frequency commands are selected as
"keypad setting", this parameter will be the initial value
of VFD reference frequency
Setting range: 0.00 Hz
–P00.03 (the Max. frequency)
60.00Hz
○
P00.11
ACC time 1
ACC time means the time needed if the VFD speeds up
from 0Hz to the Max. One (P00.03).
DEC time means the time needed if the VFD speeds
down from the Max. Output frequency to 0Hz (P00.03).
TD20 series VFDs have four groups of ACC/DEC time
which can be selected by P05. The factory default
ACC/DEC time of the VFD is the first group.

Running
direction
selection
0: Runs at the default direction, the VFD runs in the
forward direction. FWD/REV indicator is off.
1: Runs at the opposite direction, the VFD runs in the
reverse direction. FWD/REV indicator is on.
Modify the function code to shift the rotation direction of
the motor. This effect equals to the shifting the rotation
direction by adjusting either two of the motor lines (U, V
and W). The motor rotation direction can be changed by
QUICK/JOG on the keypad. Refer to parameter P07.02.
Note:
When the function parameter comes back to the
default value, the motor's running direction will come
back to the factory default state, too. In some cases it
should be used with caution after commissioning if the
change of rotation direction is disabled.
2: Forbid to run in reverse direction: It can be used in
some special cases if the reverse running is disabled.
