BCN-C22005-696
Internal torque limit 2 (Pr.810 = "2", Pr.805, Pr.806)
• When a communication option (FR-A8NC or FR-A8NCE) is used, the Pr.805 or Pr.806 setting is used as the
torque limit value.
• When the CC-Link communication (Ver. 2) is used in the quadruple or octuple setting (Pr.544="14, 18, 114, or
118"), the torque limit value can be input using a remote register (RWwC).
• When the CC-Link IE Field Network is used, the torque limit value can be input using a remote register (RWw2).
 The torque limit setting is defined as an absolute value.
 Can also be set from operation panel or parameter unit.
 The torque can also be limited by setting a value in Pr.805 or Pr.806.
 Setting range if set by operation panel or parameter unit is "673 to 1327 (-327% to 327%)"; setting increment is 1%.
NOTE
• 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).
CC-Linkextendedsetting(Pr.544)
• The functions of the remote register can be extended.
 The program used for the conventional inverter series (FR-A5NC) can be used.
If RYD, RYE, and RYF are turned ON simultaneously, only one of these is executed.
The upper 8 bits of RWw2 are not used for the link parameter extended setting.
 When the double, quadruple, or octuple setting of the CC-Link Ver. 2 is used, station data of the master station must be also set to double,
quadruple, or octuple.
(If the master station is CC-Link Ver. 1, this setting is not available.)
 Refer to the PLC function programming manual.
NOTE
• The setting becomes valid after inverter reset.
