Monitoring of the load

Parameter
consisting of inverter, motor and application against torque and thermal limits.
No automatic reaction can be made dependent on the load display.
In the previous software versions, the rated torque was predefined by the drive.
Object pn88 now allows you to choose between different options for defining the
rated torque.

≤ 100% =>
ru50 / ru51 ru80
Display is configured by the settings in bit 2..7
Inverter limits are not consisered
Reference: 100% = current torque limit
(= limiting characteristic + parameterized torque limits
in the cs parameters + effective current limits)

the thermal load is not considered
Up to the rated speed, the reference for the actual
torque is dr09 rated torque, then the thermal perma-
nently available torque is reduced according to a 1/x
function, independent of the motor type . (Thermal
