Mitsubishi Electric FR-A820-00046 (0.4K) Instruction Manual page 272

 Torque command given by analog input (terminal 1) (Pr.804 = "0 (initial
value)")
• Torque commands are given by voltage (current) input via terminal 1.
• Set Pr.868 Terminal 1 function assignment = "3 or 4" to give the torque command via terminal 1.
• Torque commands given by analog inputs can be calibrated by the calibration parameters C16 (Pr.919) to C19 (Pr.920)
(Refer to page 487.)
 Torque command given by parameter (Pr.804 = "1")
• Set Pr.805 Torque command value (RAM) or Pr.806 Torque command value (RAM, EEPROM)to set the torque
command value.
For Pr.805 or Pr.806, regard 1000% as 0%, and set torque command by offset from 1000%.
The following diagram shows relation between the Pr.805 or Pr.806 setting and the actual torque command value.
• To change the torque command value frequently, write it in Pr.805. To change torque command value frequently, write in
Pr.805.
• When the CC-Link IE Field Network communication (FR-A8NCE/FR-A800-GF) is used, the torque command given from
the remote register (RWw2) is valid.
NOTE
• When the torque command is set by Pr.805 (RAM), powering OFF the inverter erases the changed parameter value.
Therefore, the parameter set value is the one saved by Pr.806 (EEPROM) when the power is turned back on.
• If giving torque command by parameter setting, set the speed limit value properly to prevent overspeeding. (Refer to
274.)
 Torque command using pulse train (Pr.804 = "2")
• Torque command given by the pulse train input to the FR-A8AL is available.
