Function
Decrease the output frequency according to the overload condition when the motor torque reaches a
certain set level. This function will be invalid when setting a torque limit parameter at 250.
You can also select limiting the constant output or constant torque in the constant output zone.
This function will not work when the parameter
=
,
,
7
setting.
Setting methods
When setting limits to torque, use internal parameters (Torque limits can also be set with an external control device.)
With the parameter
f454
, you can select the item for limit treatment in the constant output zone (somewhat weak
magnetic field) from constant output (
f454
=
0
: default setting) or constant torque (
f454
=
1
).
Output voltage limit option(
f307
=
1
) is recommended for the parameter
f307
(supply voltage correction).
Power running torque limit and regenerative braking torque limit can be set with the parameters
f441
and
f443
.
