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

=


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).
