1)
Rated output of a typ. 6-pole standard induction motor based on I

or I
H
at 575 V 3 ph. AC 60 Hz.
3)
The base load current I
L
is based on a duty cycle of 110 % for 60 s or 150 % for 10 s with a duty cycle duration of 300 s.
4)
The base load current I
H
is based on a duty cycle of 150 % for 60 s or 160 % for 10 s with a duty cycle duration of 300 s.
5)
The specified power loss represents the maximum value at 100 % capacity utilization. The value in normal operation is
lower.
6)
Total of all motor cables. Longer cable lengths for specific configurations are available on request, see SINAMICS - Low
Voltage Configuration Manual on the customer DVD supplied with the device.
7)
With option L08 (motor reactor):
- frame size HX/JX →supplementary cabinet 23.6" (600 mm)
with option L10 (dv/dt filter plus VPL):
- frame size FX/GX/HX/JX →supplementary cabinet 23.6" (600 mm) wide
8)
The cabinet height increases by 10" (250 mm) with degree of protection IP21, and by 16" (400 mm) for degree of pro-
tection IP23 (NEMA1 filtered), IP43 and IP54 (NEMA12 ventilated).
5.6.5
Overload capability
The Motor Modules in the chassis format are equipped with an overload reserve to handle
breakaway torques, for example.
In the case of drives with overload requirements, the appropriate base load current must,
therefore, be used as a basis for the required load.
