Air-Cooled Drives
Introduction

■
Overview
SINAMICS PERFECT HARMONY GH180 drive series
SINAMICS PERFECT HARMONY GH180 drives provide
variable-speed operation by converting utility power at a fixed
frequency and fixed voltage to variable frequency, variable
voltage power. The main characteristics of the air-cooled drives
described in this catalog are listed in the following table.

Standards and regulations
SINAMICS PERFECT HARMONY GH180 drives are developed,
manufactured and tested in Nuremberg, Germany in accor-
dance with IEC standards.
They meet the applicable requirements of the following EU
regulations:
•
Low-Voltage Directive (LVD)
A Declaration of Conformity and attached CE mark declares
conformity of the low-voltage compartments of the product
(e.g. control cabinet, excitation unit etc.) with LVD: 2014/35/EU
or 73/23/EEC (depending on the product) and the associated
standard IEC 61800-5-1.
•
EMC Directive (EMCD)
A factory certificate declares that the products satisfy the re-
quirements of EMCD: 2014/30/EU or 89/336/EEC (depending
on the product) concerning electromagnetic compatibility,
when put to their intended use and conform to the associated
standard IEC 61800-3.
•
Machinery Directive (MD)
The products are intended solely for installation as compo-
nents in a machine, system or plant. They are designed to
satisfy the relevant requirements of IEC 61800-5-1,
IEC 60204-1 and IEC 60204-11 to allow the machine manufac-
turer or system/plant integrator – by appropriate usage of the
products – to meet the requirements of the Machinery Direc-
tive.
Within the European Economic Area (EEA), operation is pro-
hibited until the conformity of the end product with Machinery
Directive 2006/42/EC has been established. It is the sole
responsibility of the machine manufacturer or system/plant
integrator to ensure this.

Benefits
Low line harmonics
•
SINAMICS PERFECT HARMONY GH180 drives meet the most
stringent IEEE 519-1992 requirements for voltage and current
harmonic distortion, even if the source capacity is no higher
than the drive rating
1)
.
•
In most cases this eliminates the need for costly and inefficient
harmonic filters and their associated resonance problems.
•
The drive protects other on-line equipment from harmonic
disturbance (computers, telephones and other power
converters).
Power quality output
•
SINAMICS PERFECT HARMONY GH180 drives reduce
common-mode voltage at the motor stator windings.
•
Minimizes drive induced torque pulsations and associated tor-
sional analysis compared to other medium-voltage topologies,
by using a motor friendly pulse width modulation (PWM) output.
•
The drive supplies a sinusoidal output that eliminates addi-
tional harmonic heating and can be used with new or existing
motors without derating.
Maximized availability
Maximized availability can be achieved with the following
options:
•
In the event of a cell failure the drive remains operational by
using the cell bypass option.
•
The drive employs a Process Tolerant Protection Strategy
(ProToPS) based on a hierarchical warning system that allows
the operator to evaluate the drive disturbance and respond
appropriately to avoid system shutdown.
Extended reliability
SINAMICS PERFECT HARMONY GH180 has an integrated
transformer which offers the following additional advantages:
•
Simple and robust way to cancel input current harmonics without
the need for input harmonic filters or a complex active front-end
•
Protects power converter semiconductors against line transients
•
Kinetic buffering
•
Completely protects the motor in case of a ground fault in the
drive, the motor cabling or insulation
•
Negligible common mode voltage allows the use of a standard
motor, thus eliminating the need for special high-voltage
insulation.
•
Limits the fault energy in the drive in the unlikely event of a fault
•
The incoming line voltage doesn't have to match the motor
voltage.

Compliance with standard IEEE 519-1992 can only be guaranteed in line
supplies without previous disturbances or already existing harmonics.
