(3) Torque command using parameters (Pr. 804 = "1")
Torque command value
400%
600%
1000%
-400%
REMARKS
 When torque command is set in Pr. 805 (RAM), powering OFF the inverter will erase the changed parameter values. Therefore,
the parameter value available when power is switched ON again is the value set in Pr. 806 (EEPROM).
CAUTION
 When giving a torque command by parameter setting, set the speed limit value to an appropriate value to prevent overspeed.
(Refer to page 126.)
(4) Torque command by pulse train input (Pr.804 = "2")
Torque command is set by pulse train input from FR-A7AL (plug-in option).
FR-A7AL needs to be installed for this function.
REMARKS
For details of the setting with the FR-A7AL, refer to the FR-A7AL instruction manual.
(5) Torque command by CC-Link communication (Pr. 804 = "3, 5, 6")
 Writing a value to Pr. 805 or Pr. 806 using the FR-A7NC or FR-A7NCE (communication option) sets the torque
command value.
 Setting Pr. 804 = "3 or 5" enables the following remote registers to transmit torque commands:
RWw1 or RWwC remote register via FR-A7NC (communication option)
RWw2 or RWw3 remote register via FR-A7NCE (communication option)
 By setting "5, 6" in Pr. 804, the range of torque command setting from FR-A7NC or FR-A7NCE (communication
option) is set from -327.68% to 327.67% (0.01% increments).

Torque command by parameter setting (Pr. 805 or Pr. 806)
with using CC-Link communication
REMARKS
For details of the setting with the FR-A7NC or FR-A7NCE, refer to the instruction manual of each options.
(6) Torque command by 16 bit digital input (Pr. 804 = 4)
 Give a torque command by 16 bit or 12 bit digital input using the FR-A7AX (plug-in option).
REMARKS
For details of the setting with the FR-A7AX, refer to the FR-A7AX instruction manual.

Torque Command Source
Torque control by Real sensorless vector
 Torque command value can be set by setting Pr. 805
Torque command value (RAM) or Pr. 806 Torque command
value (RAM,EEPROM) .
 For Pr. 805 or Pr. 806, the torque command is set by an
offset from 1000% on the assumption that 1000% is 0%.
The relationship between the Pr. 805 or Pr. 806 setting
and actual torque command value at this time is shown
on the left.
 When changing the torque command frequently, write to
Pr. 805. Performing frequent parameter write to Pr. 806 will
shorten the life of the EEPROM.
