Select the up/down function in the corresponding frequency setting mode.
If the default frequency source is the digital frequency:
In case of F12.45 = 00000, the UP/DOWN function is unavailable, and the set frequency
cannot be changed by the digital potentiometer in the monitoring status.
In case of F12.45 = 00010, the UP/DOWN function is available, and the set frequency of

F13.00=0: speed control
The control mode is speed input, and the input is frequency.
F13.00=1: torque control
The input control mode is torque input, and the input is the percentage of the rated torque
current of the motor. This is valid only in the mode of speed sensorless vector control (SVC), i.e.
F00.01=1.
The final control mode is also related to the function terminals “29: torque control
prohibition” and “28: speed control/torque control switching” as detailed below Table 7-18.
