F5-11=5 Input current of analog input terminal IF is the setting value of torque current.
F5-11=7 Combine all analog values as the setting value of torque current, and then
adjust corresponding proportion according to each coefficient.
F5-12 Input as the setting value of torque current by keypad directly. The setting
value refers to the percentage of torque current output and the rated torque
current of motor.
F5-13=0 Torque is positive which is in the same direction of motor rotation.
F5-13=1 Torque is negative which is opposite to the direction of motor rotation.

In torque control mode, the inverter controls the torque current of motor, so the motor
speed is beyond control. If the input torque command does not match the load, the
motor may accelerate or accelerate in opposite direction continuously. F5-14 is to limit
the motor speed threshold in torque control mode. When the motor reaches the speed
threshold, torque current is determined by the load torque, but beyond control of the
torque current setting value, i.e. the speed will not rise and keep in the threshold. If
motor speed drops, the torque current will be recontrolled by setting value.
F5-14=0 Defined by upper limit frequency (F0-17).
F5-14=1 Defined by VS* upper limit frequency.
F5-14=2 Defined by IS *upper limit frequency.
F5-14=3 Defined by VF*upper limit frequency.
F5-14=4 Defined by IF*upper limit frequency.
The analog signal here means gain. Gain value= Voltage/10*100% or
current/20*100%.

set each preset torque current in program operation mode respectively.
Those parameters are also applicable to preset torque operation. Please note the
definitions of multi-function input terminals in preset torque operation mode (See
Group F2: multi-function input/output terminals).
