8 Converter Cabinet Units SINAMICS S150

8.1 General information

SINAMICS S150 converter cabinets are ready-to-connect, high-output AC/AC converters in a standard cabinet. An
extensive range of electrical and mechanical options means that they can be configured easily to meet individual
requirements.
They are designed for applications with very high requirements of control performance - at both the line and motor
side.
They feature a highly dynamic, pulsed, IGBT-based rectifier/regenerative unit for unrestricted four-quadrant operation
on the line side (Active Infeed with AFE technology). The maximum current values stated in the catalogs are
available in both rectifier and regenerative operation. The Clean Power Filter installed on the line side guarantees
extremely "supply-friendly" operation with virtually negligible harmonic effects. The harmonic content of the line
current is minimal and the harmonics in the line voltage are correspondingly low. Most of the current and voltage
harmonics associated with the Active Infeed are typically significantly below 1% of rated current or rated voltage. The
total distortion factors of the current (THD(I)) and voltage (THD(V)) are typically within a range of approximately 3 %.
The Active Infeed thus complies with the strict limit values defined by standard IEEE 519 (Recommended Practices
and Requirements for Harmonic Control in Electrical Power Systems). For further information about the SINAMICS
Active Infeed, please refer to section "SINAMICS Infeeds and their properties" in chapter "Fundamental Principles
and System Description".
The motor-side inverter has a sophisticated closed-loop vector control (vector-type drive object) and can also operate
in servo control mode (servo-type drive object). A range of different speed encoder interfaces is available as option,
allowing asynchronous and synchronous motors to be operated with all common types of speed encoders (TTL / HTL
incremental encoder, SSI encoder, sin/cos encoder, absolute encoder EnDat, resolver).
If drives operating on SINAMICS S150 converters need to be stopped after a power failure, e.g. in the case of a
category 1 EMERGENCY OFF, the devices can be optionally equipped with braking units (options L61, L62, L64,
L65).
SINAMICS S150 converter cabinets are especially suitable for use in drives with
·
high requirements of dynamic control
·
frequent braking cycles with high braking energy
·
minimal harmonic effects on the supply system
SINAMICS S150 converter cabinet units are available for the line supply voltages and output power ranges listed in
the table below:
Line supply voltage
380 V – 480 V 3AC
500 V – 690 V 3AC
Line supply voltages and output power ranges of SINAMICS S150 cabinets
Line and motor-side components as well as additional monitoring devices can be installed in the SINAMICS S150
converter cabinets.
They are available in cabinet widths from 1400 mm, which then increase in increments of 200 mm.
The standard cabinet has degree of protection IP20, but further cabinets with degrees of protection IP21, IP23, IP43
and IP54 are available as options.
SINAMICS S150 converter cabinets feature as standard the AOP30 Advanced Operator Panel for control, monitoring
and commissioning tasks. It is mounted in the cabinet door.
A PROFIBUS interface is provided as standard on the CU320-2 DP Control Unit as a customer interface. If the
CU320-2 PN Control Unit (option K95) is used instead of the standard CU320-2 DP Control Unit, a PROFINET
interface is provided instead of the PROFIBUS interface.
The CU320-2 features digital inputs and outputs as standard. The TB30 Terminal Board (option G62) can be
optionally inserted in the CU320-2 option slot and / or the TM31 Terminal Module can be used (option G60 or G61).
These options provide additional digital and analog inputs and outputs.
Converter output power
110 kW - 800 kW at 400 V
55 kW - 900 kW at 500 V
75 kW - 1200 kW at 690 V
