Parameter Description
4: Multisection torque setting （100.0% is equal to the value of F1.19）
5: Telecommunication setting（100.0% is equal to the value of F1.19）
Only when F0.00=2, torque control and the function code of F8.06 is valid. Under torque
control, the inverter output the torque according to the setting torque command, the output
frequency is restricted by the upper limit frequency, when load speed is greater than the upper
limit frequency, the output frequency of inverter is restricted and will be indifferent with the
setting torque.
When the torque command is keyboard setting (when F8.06 is 0), torque command is
obtained by setting the function code F8.07. When the torque setting is negative, the motor will
reverse. Keyboard setting, analog value, multi-speed and communication setting, 100.0% that
inputs is equal to the motor rated current of F1.19 times, -100.0% that inputs is equal to the
motor rated current of negative (reverse) F1.19 times .
Through the multi function input terminal,can switch between torque control and speed
control.
When the set torque is greater than the load torque, output frequency of the inverter will
increase, when output frequency of the inverter arrive upper limit frequency, the converter runs
at the upper limit frequency all the time.
When the set torque is less than the load torque, output frequency of the inverter will decrease,
and when output frequency of the inverter arrives lower limit frequency which the inverter runs
at all the time.
Note:When stop command is valid, inverter switch from torque control to speed control
automatically.

Option of the upper frequency setpoint Sources. Especially in the torque control, the output
frequency of the inverter can be changed by changing the upper limit frequency.
0: Keyboard set the upper limit Freq. (F0.05)
1: Analog AVI set upper limit Freq.( 100%corresponds to the max. fre. of F0.04)
2: Analog ACI set upper limit Freq.(the same as 1)
3: Multisection setting upper limit Freq. (the same as 1)
4:Telecommunication setting upper limit Freq. (the same as 1)
