Siemens SINAMICS V90 Operating Instructions Manual page 61

Note
• Continuous operating area is a series of states when a motor can operate continuously
and safely. The effective torque must be located in this area.
• Short-term operating area is a series of states when a motor can operate for a short
duration if its effective torque is larger than the rated torque.
• For the motors with different rated and maximum speeds, the output torque will decline at
a faster rate after the speed exceeds the rated speed.
• The feature in short-term operating area varies with power supply voltages.
• The continuous operating area becomes smaller and the voltage consumptions on the
cables grow larger when the cables in the major loop exceed 20 m.
