Setting the torque limit level
Limit the output torque not to exceed the specified value.
The torque limit level can be set in a range of 0% to 400%.
The torque limit level can be selected by using the analog input terminal (terminal 1).

Initial values differ according to the inverter capacity and the control method. For details, refer to the FR-E800 Instruction Manual
(Function).
NOTE
• 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.
• Under PM sensorless vector control, 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.
