Torque Command / Torque Limit Via Profibus Communication (Pr.804) (Only For The Fr-A800 Series) - Mitsubishi Electric 800 Series Instruction Manual

7.8.2 Torque command / torque limit via PROFIBUS communication (Pr.804) (only for
the FR-A800 series)
Setting Pr.804 Torque command source selection = "3 or 5" enables torque command / torque limit via PROFIBUS
communication under Real sensorless vector control, torque control under vector control, and speed control.
(When Pr.804  "3 or 5", writing a torque command/limit value via PROFIBUS communication causes turning ON of Alarm 1 to
Alarm 7 corresponding to REF1 to REF7, resulting in generation of a command execution error.)
