Torque command by parameter setting (Pr. 805 or Pr. 806)
(-400% to 400%)
3
Torque command by
parameter setting
(Pr. 805 or Pr. 806)
(-400% to 400%)
Torque command with using CC-Link
communication (FR-A7NC)
Setting from the remote resister can be
made. (-400% to 400%)
4 12 bit/16 bit digital input (FR-A7AX)

Torque command by
parameter setting
(Pr. 805 or Pr. 806) with
using communication
other than CC-Link
communication
(-400% to 400%)
Torque command with using CC-Link
communication (FR-A7NC)
Setting from the remote resister can be
made. (-327.68% to 327.67%)
6
Torque command with using CC-Link
communication (FR-A7NC)
(-327.68% to 327.67%)
805
Torque command
value (RAM)
1000%
600 to
1400%
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%.
806
Torque command
value
(RAM,EEPROM)
1000%
600 to
1400%
Writes the torque command value to the RAM and EEPROM.
On the assumption that 1000% is 0%, the torque command is set by
an offset from 1000%.
⋅ 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 288 )
