 Input method of torque command
Torque command may be input in either of the following two ways:
 Set the torque commands at 0 and H7FFF (H7FF) signal inputs
Set the torque command value when the input signal is
"0" in Pr.447 and the torque command value when the
input signal is "H7FFF (H7FF) in Pr.448.
The figure on the right shows the case when the torque
command value is set using input signal H7FFF (H7FF)
when the torque command value is 150% (initial value of
Pr.448). When the most significant bit of input signal is
positive, a negative torque command value (-150%) is
also set at the same time.
 Use the digital input value as the torque command
When "9999" is set in Pr.448, the input signal is considered as a torque command value.
For example, the torque command value when the input signal is H190 is 400%, as shown below.
Even if a value higher than H190 is input, the torque command value is clamped at 400%.
