Torque command
For torque control selection, the torque command source can be selected.
*1 Torque commands can be input via CC-Link, CC-Link IE TSN, CC-Link IE Field Network Basic, and PROFIBUS-DP communication. CC-Link and
PROFIBUS-DP communication are unavailable when the Vector control compatible options is installed.
 Control block diagram
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 page 136 .)
 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.
