The technical data of the power modules is specified in Table 5-1 for the 1–axis
version and in Table 5-2 for the 2–axis version.
The specified values are valid for:
S
The specified rated frequency (inverter pulse frequency)
S
Maximum ambient temperature of 40 °C
S
Installation altitude<1000 m above sea level
Derating must be applied for conditions that deviate from those specified above.
The power modules do not have any overload protection, but only a current
acquisition without its own processing. The overload protection is realized in the
SIMODRIVE 611 control unit.
Also refer to the definition of the load duty cycles (Fig. 5-2 to 5-5)

The following restrictive conditions must be met:
for induction motors:
– The no–load current of the motor (I
rent of the power module (according to Table 5-1).
– On the basis of the actual current value resolution, the lowest occurring
no–load current of the motor must satisfy the following condition:

Appropriate values are specified in Table 5-1 and 5-2 to dimension the cabinet
cooling. These are defined as follows:
S

hose cooling
S
P Power loss that cannot be dissipated using hose cooling or
Vint
external cooling (this power loss remains in the control cabinet)
For components with internal cooling, the complete dissipated power loss re-
mains in the control cabinet.
