NOTE
• For the details of the CC-Link communication, refer to the FR-A8NC E kit Instruction Manual. For the details of the CC-Link IE
TSN or CC-Link IE Field Network, refer to the Instruction Manual (Communication).
 Second torque limit level (TL signal, Pr.815)
• For Pr.815 Torque limit level 2, when the Torque limit selection (TL) signal is ON, the setting value of Pr.815 is the limit
value regardless of the setting of Pr.810 Torque limit input method selection.
• To assign the TL signal, set "27" in any parameter from Pr.178 to Pr.189 (Input terminal function selection).
NOTE
• Changing the terminal assignment using Pr.178 to Pr.189 (Input terminal function selection) may affect the other functions.
Set parameters after confirming the function of each terminal.
 Setting the torque limit values during acceleration/deceleration
individually (Pr.816, Pr.817)
• The torque limit during acceleration and deceleration can be set individually. Torque limit using the setting values of Pr.816
Torque limit level during acceleration and Pr.817 Torque limit level during deceleration is as follows.
• If 1 second elapses while the difference between the set speed and rotation speed is within ±2 Hz, the torque limit level
during acceleration/deceleration (Pr.816 or Pr.817) changes to the torque control level during constant speed (Pr.22).
