The torque limit for setup mode with machine data
MD1239 $MD_TORQUE_LIMIT_FOR_SETUP (torque limit setup mode)
or the force limit
MD1239 $MD_FORCE_LIMIT_FOR_SETUP also acts symmetrically about the force due to
weight. The minimum is selected from the limit of NC and setup mode if setup mode is
active.
With SIMODRIVE 611 digital, the limits for NC and setup mode are no longer included in
● the reference values for ramp-function generator follow-up
● the capacity utilization and
● the M < Mx signaling function.
