S6- intermittent service characteristic curve at 25% operating time
of the motor (according to EN 60034-1; 1998). The maximum cycle time
is 15 min.
[M
max
]: The theoretically possible maximum torque of the motor. It can be
limited by the drive control device.
[1]-[4]: Voltage limiting characteristic curves. Starting at a breakpoint
speed, the voltage limiting characteristic curve limits the available
maximal moment M
max
. The maximum motor speed is determined by
the intermediate circuit voltage used. Separate characteristic curves
result for the individual drive control devices in association with the
supply device and the power connection voltage used.
