FR-A800
5 - 85
When changing from V/F control or Advanced magnetic flux vector control to Real sensorless
vector control or vector control in FR-A820-00250(3.7K) or lower or FR-A840-00126(3.7K) or lower,
150% changes to 200%.
813
H702
Torque limit level (3rd
quadrant)
9999
0 to 400%
Set the torque limit level for reverse rotation power
driving.
9999
Limit using Pr. 22 or the analog terminal values.
814
H703
Torque limit level (4th
quadrant)
9999
0 to 400%
Set the torque limit level for reverse rotation
regenerative driving.
9999
Limit using Pr. 22 or the analog terminal values.
815
H710
Torque limit level 2
9999
0 to 400%
When the torque limit selection (TL) signal is ON,
Pr. 815 is the torque limit value regardless of Pr. 810.
9999
The torque limit selected in Pr. 810 is valid.
816
H720
Torque limit level during
acceleration
9999
0 to 400%
Set the torque limit value during acceleration.
9999
The same torque limit as constant speed.
817
H721
Torque limit level during
deceleration
9999
0 to 400%
Set the torque limit value during deceleration.
9999
The same torque limit as constant speed.
858
T040
Terminal 4 function
assignment
0
0, 1, 4, 9999
The torque limit level can be changed with setting
value "4" and the signal to terminal 4.
868
T010
Terminal 1 function
assignment
0
0 to 6, 9999
The torque limit level can be changed with setting
value "4" and the signal to terminal 1.
874
H730
OLT level setting
150%
0 to 400%
A trip can be set for when the torque limit is activated
and the motor stalls. Set the output at which to
activate the trip.
NOTES
The lower limit for the torque limit level under Real sensorless vector control is set to 30% even if a
value lower than 30% is set.
When the low-speed range high-torque characteristic is disabled under PM sensorless vector con-
trol (Pr. 788 = "0"), the torque limit is not activated in a low-speed range with a rated frequency of
less than 10%.
Under PM sensorless vector control, the torque limit level is reduced inversely proportional to the
output frequency in the constant output range of the rated motor frequency or higher.
