Description
Setting range: 0.0–300.0% (of the motor rated
current)
(P90.40=1 Torque limit mode)
0.0–200.0%
During the running, when the torque feedback
value is equal to or greater than P90.42, brake
release timing is entered.
(It is valid only when P90.04=1, which indicates
the brake is controlled by the VFD, and the VFD
uses the torque mode.)
0.00–50.00HZ
Used in torque/speed switchover mode 2
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
brake release. During stop, quick demagnetizing
needs to be implemented to prevent slip in case
of overdue brake closing.
P91.00 setting range: 0–1
0: Disable
1: Enable
P91.00=0: Disable. Normal voltage curves are
used.
P91.00=1: Conical motor voltage curves are
used.
P91.01 setting range: P91.02–150.0%
(100.0% corresponds to the motor rated
voltage.)
P91.02 setting range:
P91.03 setting range:
-339-
P91.03–P91.01
0.0–P91.02
