Y15
Sine-wave filter (SINAMICS GM150 in the IGBT version and
SINAMICS SM150 in the IGBT version on request)
Sine-wave filters are required for the following applications:
•
When operating old motors (retrofit)
•
When operating third-party motors without taking supplemen-
tary measures for converter operation
The sine-wave filters supply the motors with almost sinusoidal
motor currents and voltages so that line motors can be operated.
The sine-wave filter operates optimally for motors with a rated
frequency of 50 Hz or 60 Hz. It should be noted that only driven
loads with a square-law load torque may be operated (e.g.
pumps, fans). The output frequencies used in operation can lie
in the range between 30 Hz and 66 Hz.
A field weakening range of 1:1.1 is permissible (max. 55 Hz for
50 Hz motors and max. 66 Hz for 60 Hz motors).
When sine-wave filters are used, the voltage harmonic distortion
at an output frequency of 50 Hz is less than 5 %.
If the sine-wave filter is used, the output of the converter must be
reduced (
see Technical specifications
).
Note:
The rated motor current, the motor current in the operating point
and the motor no-load current must be given in plain text when
ordering filters.

Option
Y15
increases the width of the cabinet unit
(
for dimensions see Technical specifications
).
Y17
Line reactor
(static excitation unit, see Accessories, Chapter 7)
With the option
Y17
a line reactor is integrated to protect against
excessive harmonic currents and to limit the circuit feedbacks.
The exact values for the reactor must be given in plain text as
they are dependent on the supplying network.
Y40
Raw water data deviating from the catalog data
(with water cooling, on request)
With option
Y40
, raw water whose data does not conform to the
Technical specifications can also be used with water-cooled
converters (
for specifications, see Cooling unit, Pages 9/8 and
9/9
). Deviations from the values indicated in the specification
must be clarified in advance.
Y73
Braking resistor
(SINAMICS SM150 on request only)
The braking resistor is connected to the Braking Module
(option
L72
) via two connections (SINAMICS GM150 in the
IGBT version) or three connections (SINAMICS GM150 in the
IGCT version and SINAMICS SM150 in the IGCT version).
For dimensioning,
refer to the Table in the description for
option
L72
, Page 6/27
.
Notice:
The power loss of the braking resistor must be taken into
account when dimensioning the room or the area in which the
converters is mounted. If required, the braking resistor should
be mounted outside the room/area. The braking resistor is
equipped with a temperature monitor. This must be connected
up so that when it responds, the converter is shut down. Regard-
ing inductance
L
, the following requirements apply to the
braking resistor and cable routing: The time constant
L/R
must not exceed 20 μs, i.e.
L
must be less than
R
× 20
µ
s.
The signal cables to the temperature monitoring and the
power cable are not included in the scope of supply.
Note:
When ordering, the following data must be specified in plain text:
max. rated power, braking duration and cycle. The Technical
specifications are obtained, based on this data (for example,
dimensions, weight), whereby the following basic data apply to
all resistors:
•
Degree of protection IP20, with perforated sheet steel roof
section manufactured out of V2A steel
•
Cooling using an internal fan
•
Digital feedback signal from the air flow switch and
temperature switch
•
Mounted outside the converter, in electrical rooms and areas
•
Ambient temperature: max. converter ambient temperature
•
