Mitsubishi Electric 800 Series Instruction Manual page 121

• Torque commands given by analog inputs can be calibrated by the calibration parameters C38 (Pr.932) to C41 (Pr.933)
(Refer to page 287.)
 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. Writing values in Pr.806 frequently will shorten the life
of the EEPROM.
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
122.)
 Torque command via communication (Pr.804 = "3 or 5")
• Set the torque command value via CC-Link (FR-A8NC / PLC function), CC-Link IE TSN, CC-Link IE Field Network Basic,
and PROFIBUS-DP communication (FR-A8NP).
• For speed limit when "3 or 5" is set in Pr.804, Pr.807 Speed limit selection becomes invalid and Pr.808 Speed limit and
Pr.809 Reverse-side speed limit become valid for speed limit. (When Pr.544 CC-Link extended setting = "0, 1, 12, 100,
or 112")
• Pr.807 is valid when the extended cyclic setting of CC-Link communication is quadruple or octuple.
