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 in a short duration if its effective torque is
smaller 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 drop grows larger when the cables in the major loop
exceed 20 meters.
• For 1FL6096 motors, the maximum speed can be ensured when the line supply voltage is higher than 380 V.
Permissible radial and axial forces
Note
1FL604❑ and 1FL609❑ have a 5 mm of shaft sheltered in sleeves, and 1FL606❑ has an 8 mm of shaft in sleeves.
Therefore, the distances to flange in the above three figures begin respectively from 5 mm, 8 mm, and 5 mm.
