Torque Command - Mitsubishi Electric FR-A8AX Instruction Manual

 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%.
