Simodrive 611A Msd Or Simodrive - Siemens SINUMERIK 840C Installation Instructions Manual

12.93
12.24.4 Travel to fixed stop with fixed clamping torque (torque limitation via terminal 96)
The NC setpoint interface then outputs a voltage value according to the setting in NC MD
1144* Switchover current setpoint; however, the current limitation in the actuator becomes
operative as a result of the activation of terminal 96.
The NC outputs the interface signal FIXED STOP REACHED to the PLC.
The NC consequently deletes the remaining distance to go and switches the axis to follow-up
mode.
The PLC sends an edge signal ACKNOWLEDGEMENT FIXED STOP REACHED to the NC.
A block change is then performed. The current setpoint, and thus also the clamping torque,
remain applied.

12.24.4.2 SIMODRIVE 611A MSD or SIMODRIVE 660

With these systems, a torque limitation is entered in a free gear stage in the actuator. When
the function is selected, the PLC activates the free gear stage, thus making the torque
limitation operative. Setpoints must be input via terminals 56/14.
