0: F2-10
The torque upper limit in speed control mode
is set by F2-10 (digital setting of torque upper
limit in speed control).
1: AI1
The torque upper limit is input with the current
or voltage signal through the AI1 terminal. The
frequency is calculated according to the preset
AI curve.
2: AI2
The torque upper limit is input with the current
or voltage signal through the AI2 terminal. The
frequency is calculated according to the preset
AI curve.
3: AI3
The torque upper limit is input with the current
or voltage signal through the AI3 terminal. The
frequency is calculated according to the preset
AI curve.
5: Communication
The main frequency is set through
communication. The running frequency is input
through remote communication. The AC drive
must be equipped with a communication card
to implement communication with the host
controller. This mode applies to remote control
or centralized control systems of multiple
equipment.
6: MIN (AI1, AI2)
The torque upper limit in speed control mode
is the smaller value between AI1 and AI2 inputs.
7: MAX (AI1, AI2)
The torque upper limit in speed control mode
is the larger value between AI1 and AI2 inputs.
8: F2-12
The torque upper limit in speed control mode
is set by F2-12 (torque upper limit reference in
speed control (generating)).

150.0% 0.0% to 200.0%
The torque upper limit under generating state
takes the rated current of the AC drive as the
base value.
There are eight torque upper limit sources available in speed control mode. In motoring state, the
torque upper limit source is determined by F2-09; in generating state, the torque upper limit source is
defined by F2-11.
