Torque Limit
The positioning unit RTEX supports a function (torque limit) to change the maximum torque for the AMP
in real time. The torque limit can be arbitrarily changed during the torque limit operation, however, note
that the torque cannot be changed in the home return operation.
The specified torque limit value is used as the maximum torque during the torque limit operation. Also,
the torque limit cannot be specified by the setting tool, Configurator PM. Data must be written into the
shared memory from the PLC in order to carry out the torque limit. Followings are the details of the
shared memory to carry out the torque limit.

15 to 0 Torque limit value
3000 Sets the torque limit value.
The unit is (0.1%).
If 2000 is written in this area, it operates with “2000 x 0.1
= 200 (%)” as the maximum torque.
