Braking Module
In order to permit braking operation for Basic Infeed
(SINAMICS GM150) or for Active Infeed (SINAMICS SM150) to
be able to brake even if the power fails, a Braking Module with
braking resistor can be used. The mechanical design of the
Braking Module corresponds to that of a Motor Module; its actual
version is adapted to the converter cooling type (air or water
cooling).
The following should be ensured when engineering:
•
Shielded cables should be used just the same as at the
converter output.
•
The same maximum cable lengths as for SINAMICS GM150
in the IGBT version apply (without sine-wave filter or output
reactor;
refer to Power cables, Page 9/13
).
•
Regarding 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.
Note:
An external load resistor is connected as the braking resistor.
This is not included in the scope of supply
(option
Y73
see
Page 6/42)
.
Note:
Option
L72
cannot be combined with option
M61
(redundant fan
in the power unit).
Note:
For SINAMICS SM150 in IGCT version, option
L72
on request.
Note:
For SINAMICS GM150 in IGCT version, option
L72
cannot be
combined with option
N15
(24-pulse Basic Line Module).
Notice:
With option
L72
the cabinet width is increased as follows:
•
SINAMICS GM150 in the 12-pulse IGBT version: 600 mm
•
SINAMICS SM150 in the IGCT version: 1800 mm
