Writes the torque command value to the RAM.
On the assumption that 1000% is 0%, the torque command is set by
an offset from 1000%.
Writes the torque command value to the RAM and EEPROM.

Vector control
⋅ Torque command is given by voltage (current) input to
terminal 1.
⋅ When torque command is input from terminal 1, set "4 or
3" in Pr. 868 Terminal 1 function assignment.
⋅ Torque command by analog input can be calibrated using
calibration parameter C16 (Pr. 919) to C19 (Pr. 920) . (Refer
to page 295 )
Select the torque command in the
constant power region by torque
command setting.
