Largest permitted setpoint value for a force control. A larger setpoint value leads to a fault or
warning.
If both the smallest (PNU 511) and the largest (PNU 512) permissible force setpoint value are set to
zero, the setpoint limits are ignored when executing a force task.

Max. permitted speed after start of a force command. This parameter is used for monitoring, not to
limit the speed. If the actual speed exceeds the set value, a fault is indicated, the axis stops and the
force command is cancelled.
The speed limit value must be significantly larger than the speed limit of parameters 406 / 554,
otherwise monitoring will lead to an error when reaching the speed limit. The speed limit value
should preferably be used as a security when the speed limiting (406/554) was deactivated.
