Derating data, chassis format

SINAMICS S120 Chassis Format Units and the associated system components are rated for an ambient temperature of 40 °C and installation altitudes up to 2000 m above sea level.

For ambient temperatures > 40 °C the output current must be reduced. Ambient temperatures above 55 °C are not permissible.

At installation altitudes > 2000 m above sea level, it must be taken into consideration that with increasing height, the air pressure decreases and therefore the air density. As a consequence, the cooling efficiency and the insulation capacity of the air also decrease.

Due to the reduced cooling efficiency, it is necessary, on one hand, to reduce the ambient temperature and on the other hand, to lower heat loss in the chassis unit by reducing the output current, whereby ambient temperatures lower than 40 °C may be offset to compensate.

The following table lists the permissible output currents as a function of the installation altitude and ambient temperature. The specified values already include a permitted compensation in respect of installation altitude and ambient temperatures < 40 °C – temperature at the air intake of the chassis unit.

The values apply under the precondition that a cooling air flow through the units is guaranteed as stated in the technical specifications.

As additional measure for installation altitudes from 2000 m up to 5000 m, an isolating transformer is required in order to reduce transient overvoltages according to EN 60664-1.
For additional information, please refer to the SINAMICS Low Voltage Engineering Manual.

Current-derating factors for SINAMICS S120 chassis units as a function of the ambient/air intake temperature and the installation altitude

Current derating for Motors Modules, chassis format as a function of the pulse frequency

To reduce motor noise or to increase output frequency, the pulse frequency can be increased relative to the factory setting (1.25 kHz or 2 kHz). When the pulse frequency is increased, the derating factor of the output current must be taken into account. This derating factor must be applied to the currents specified in the technical data.

For additional information, please refer to the SINAMICS Low Voltage Engineering Manual.

The following table lists the rated output currents of the SINAMICS S120 Motor Modules with pulse frequency set in the factory as well as the current derating factors (permissible output currents referred to the rated output current) for higher pulse frequencies.

Overload capability

SINAMICS S120 chassis units have an overload reserve, e.g. to handle breakaway torques. If larger surge loads occur, this must be taken into account when configuring. In drives with overload requirements, the appropriate base load current must, therefore, be used as a basis for the required load.

The permissible overload levels are valid under the prerequisite that the drive units are operated with their base load current before and after the overload condition based on a duty cycle duration of 300 s.

For short, repeating load cycles with significant load fluctuations within the load cycle, the appropriate sections in the SINAMICS Low Voltage Engineering Manual must be observed.

Power Modules and Motor Modules

The base load current for a low overload IL is the basis for a duty cycle of 110 % for 60 s or 150 % for 10 s.

Low overload

The base load current for a high overload IH is the basis for a duty cycle of 150 % for 60 s or 160 % for 10 s.

High overload

Line Modules

The base load current for a high overload IH DC is the basis for a duty cycle of 150 % for 60 s or Imax DC for 5 s.

High overload

Radio interference suppression

SINAMICS drive converter systems are not designed for connection to the public network (first environment). Radio interference suppression is compliant with the EMC product standard for variable-speed drives EN 61800-3, "Second environment" (industrial line supplies). The equipment can cause electromagnetic interference when it is connected to the public network. However, if supplementary measures are taken (e.g. → line filter), it can also be operated in the "first environment".
