6: Torque limit value 1
When this function is selected, it shall be used together with the P05.13 function code setting. The analog
input meaning is the same as torque offset.
7: Torque limit value 2
When this function is selected, it shall be used together with the P05.14 function code setting. The analog
input meaning is the same as torque offset.
8: Torque command (reference)
When this function is selected, it shall be used together with the P06.02 function code setting. The analog
input meaning is the same as torque offset.
9: Main set frequency reference (unipolar)
The meaning of this function is the same as 1, the only difference lies in that the analog input polarity
does not affect the running direction of the drive, which is determined by P02.03 or the forward and
reverse terminals or communication setting.
A: Auxiliary set frequency reference (unipolar)
The meaning of this function is the same as 2, the only difference lies in that the analog input polarity
does not affect the direction of auxiliary frequency. When the auxiliary frequency can be used as the main
reference switching frequency, its running direction is determined by P02.03 or the forward and reverse
terminals or communication setting.
B: Motor temperature detection
The motor temperature resistance switches into the analog voltage input value by hardware processing
as the detection value of the motor temperature.
C: V/F output voltage offset
When the analog input is the voltage signal, and the analog input terminal function is the output voltage
offset, the corresponding output voltage offset is as shown in Fig.6-49.
Fig. 6-49 Output voltage offset
Assuming that the output voltage corresponding to the set frequency in the V/F curve is V
f
, the relation
between the input analog signal and the offset voltage is as follows:
The corresponding offset voltage of the -10V~0V/4mA analog input V
AI
is V

= -V
f.
The corresponding offset voltage of the 10V/20mA analog input V
AI
is V
