mode is automatically used.
3: Torque/speed switchover mode 2 (horizontal
moving)
Since the brake
torque/speed switchover is set through P90.44.
The set frequency needs to be greater than
P90.44.
Setting range: 0.0–300.0% (of the motor rated
current)
During the vector control in speed mode, the
torque amplitude is limited within the delay time
before brake release, after brake release,
before brake closing, or after brake closing.
0.0–200.0%
During running, when the torque feedback
value is greater than or equal to P90.42, it
enters the brake release timing. (It is valid only
when P90.04=1, which indicates the brake is
controlled by the VFD, and the VFD uses the
torque mode.)

1: Mode 1
0–2
0: No switchover (Same as ACC/DEC time for
FWD rotation.)
1: Switch to the DEC time. (P08.05 is used.)
2: Switch the ACC/DEC time. (P08.04 and
P08.05 are used.)
Description
The conical motor does not require external
braking since it implements braking by using
internal magnetic flux control. During start, the
starting frequency needs to be increased for
