Torque command by analog input (terminal 1) (Pr.804="0 (initial value)")
• Torque commands are given using voltage (current) input to the terminal 1.
• Set Pr.868 Terminal 1 function assignment="3, 4" to use the terminal 1 for torque command inputs.
• Torque commands given using analog inputs can be calibrated by calibration parameters Pr.919 and Pr.920 (Refer to
page 407.)
Torque command by parameter (Pr.804="1")
• Torque command values can be set by setting Pr.805 Torque command value (RAM) and Pr.806 Torque command
value (RAM, EEPROM).
• 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 torque command value frequently, write in Pr.805. If values are written in Pr.806 frequently, EEPROM life is
shortened.
• When FR-A8NCE (CC-Link IE Field communication option) is mounted, torque command from FR-A8NCE is enabled.
NOTE
• When the torque command is set by Pr.805 (RAM), powering OFF the inverter will erase the changed parameter value.
Therefore, the parameter set value will be the one saved by Pr.806 (EEPROM) when the power is turned back on.
• If providing torque command by parameter setting, set the speed limit value properly to prevent overspeeding. (Refer to
195.)
