13.7 Torque Limit
FP7 MC Unit supports a function (torque limit) to change the maximum torque for the AMP in
real time.
The torque limit can be arbitrarily changed when this unit is operating. However, the torque
limit 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 set by the setting tool "Control Motion Integrator"
because it is a function that can be changed when the unit is operating. Data must be written
into the unit from PLC to perform the torque limit. The descriptions of the unit memories to
perform the torque limit are as follows.
