• Use Pr.432 Pulse train torque command bias and Pr.433 Pulse train torque command gain to set the bias and gain
values for the torque command respectively.
NOTE
• For the details of the FR-A8AL, refer to the Instruction Manual of the FR-A8AL.
 Torque command given through the CC-Link / CC-Link IE Field Network /
PROFIBUS-DP (Pr.804 = "3, 5, 6")
• Set the torque command value via the CC-Link communication (FR-A8NC/PLC function), CC-Link IE Field Network
communication (FR-A8NCE/FR-A800-GF), or PROFIBUS-DP communication (FR-A8NP).
• For speed limit when "3 or 5" is set in Pr.804 via the CC-Link communication, Pr.807 Speed limit selection becomes
invalid and Pr.808 Forward rotation speed limit/speed limit and Pr.809 Reverse rotation speed limit/reverse-side
speed limit become valid for speed limit. (When Pr.544 CC-Link extended setting = "0, 1, 12, 100, or 112")
• For the CC-Link communication, Pr.807 is valid when the extended cyclic setting of CC-Link communication is quadruple
or octuple. For CC-Link IE Field Network, Pr.807 is always valid.
