Parameter
Torque command using parameters (Pr. 804 = 1)
● 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.
Torque command value
600%
NOTE 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.
