different from the setup torque.
In case of torque control, the torque command is the torque upper limit, and
set by the torque upper limit source (F2-09).
It can perform switching between torque control and speed control via the
multifunctional input terminals.
In case of torque control, the output frequency of the driver automatically
tracks the change of the load speed, but the change of the output frequency
is affected by the setup acceleration/deceleration time. If it needs to quicken
the tracking speed, the acceleration/deceleration time shall be shortened.
When the setup torque of the driver is higher than the load torque, the output
frequency of the driver will rise; when the output frequency of the driver
reaches the frequency upper limit, the driver will keep running with the
frequency upper limit.
When the setup torque of the driver is lower than the load torque, the output
frequency of the driver will fall; when the output frequency of the driver
reaches the frequency lower limit, the driver will keep running with the
frequency lower limit.

In the speed control mode, F2-09 is used to select the setup source of torque
upper limit. When setting via the analog value, 100% of the analog input
setup corresponds to F2-10, and the setup 100% corresponds to the rated
torque of the motor matching the driver.
In the torque control mode, torque upper limit source is the torque setup
source. Torque upper limit is the torque setup command.
