2.1 Speed–torque diagrams<br />
Note<br />
� DC link voltages > 600 V occur when the motors are fed from drive converters<br />
connected to 480 V line supplies. The following restrictions apply:<br />
– Shaft heights 36, 48, 63 <strong>and</strong> 71 may only be utilized to ∆T = 60 K.<br />
– Shaft heights 100 <strong>and</strong> 132 may still be utilized to ∆T = 100 K.<br />
� For a description of the shift of the voltage limiting characteristics, refer to the<br />
documentation ”General Section”.<br />
� The specified thermal S3 limits are referred to ∆T = 100 K.<br />
Note<br />
For <strong>1FT5</strong> motors, the rotor moment of inertia is specified without tachometer.<br />
