NOTE
• When the torque command exceeding the torque limit value (Pr.22, Pr.810, Pr.812 to Pr.817) is given, the output torque is
within the torque limit value. (Refer to
 Torque command given by analog input (terminal 4) (Pr.804 = "0" (initial
value))
• Torque commands are given by voltage (current) input via terminal 4.
• Set Pr.858 Terminal 4 function assignment = "4" to give the torque command via terminal 4.

Description
Set the torque current limit level.
The torque limit setting value is used for limiting the torque current level.
Constant motor output command
Constant torque command
The torque is constant unless the
output limit of the torque current is
reached. (The torque current is
limited.)
Torque command given by analog input via terminal 4
Torque command (-400% to 400%) given by the parameter setting
(Pr.805 or Pr.806)
Torque command via communication
12/16-bit digital input (FR-A8AX)
Torque command via communication
Writes the torque command value in RAM. Regards 1000% as 0%, and
set torque command by an offset of 1000%.
Writes the torque command value in RAM and EEPROM Regards
1000% as 0%, and set torque command by an offset of 1000%.
