Mitsubishi Electric FR-A820-00046 Instruction Manual page 299

Parameters Speed control under Real sensorless vector control, vector control, PM sensorless vector control
● When the CC-Link communication (Ver. 2) is used in the quadruple or octuple setting (Pr. 544 =
"24, 28, or 128"), the torque limit value can be input using a remote register (RWwC to RWwF) for
each of the four quadrants.
Fig. 5-18:
NOTES If "2" is set in Pr. 810 while the communication option is not connected, a protective function
(E.OPT) is activated (when the PLC function is disabled).
For the details of the FR-A8NC and the FR-A8NCE, refer to the Instruction Manual of each option.
For the details of the CC-Link IE Field Network, refer to page 5-747.
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 of Pr. 178 to Pr. 189 (input terminal function selection).
Fig. 5-19:
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.
