Manual SD6
Shows the current utilization of the motor as a %. The reference quantity is the
nominal power loss of the motor. It is derived from copper losses and speed-
dependent losses from magnetic reversal and friction. The nominal copper
losses are derived from the nominal motor current (B12) calculated with the
stator resistance (B53). Speed-dependent nominal losses are calculated from
the nominal motor speed (B13) and the coefficients of friction (B73 and B74).
The motor utilization that is displayed accordingly depends on the actual values
for motor current (E00) and motor speed (E91).
Level of the thermal motor model (i
2
t model). 100 % is equivalent to full
utilization. The thermal model is based on the rating data entered under group
B.. (motor), i.e. continuous operation (S1 operation). The response
parameterized in U10, U11 for the event"45:overtemp.motor i2t" is triggered at
over 100 %.
Currently active positive torque/force limit. The reference value for
consideration on the load side is C09, for consideration on the motor side B18.
Currently active negative torque/force limit in reference to B18. The reference
value for consideration on the load side is C09, for consideration on the motor
side B18.
