SINAMICS GM150 SINAMICS SM150
Supplement for Catalog D 12 2012
7.3
Updated option descriptions
7.3.1
K80
Control of "Safe Torque Off" function
(SINAMICS SM150; SINAMICS GM150 on request)
The description of option K80 has to be supplemented as follows.
Note
When option K80 is selected, only DRIVE-CLiQ cables with a maximum length of
30 m can be used.
7.3.2
L53
UPS for the power supply of the open-loop and closed-loop
control (SINAMICS GM150)
The description of option L53 has to be supplemented as follows.
Caution
The battery to supply the UPS is no longer supplied, and must be ordered before
commissioning starts. This avoids deep discharge when longer transport and
storage times are involved.
Battery article number: 6SL3988-6YX00-0AA0
7.3.3
L72
Braking Module
The description of option L72 has to be supplemented as follows.
Note
•
With option L72 the deionized water requirement of the cooling unit is higher
than that specified in the technical data. The additional deionized water
requirement is as follows:
– for 12-pulse Basic Line Modules: 4 l
– for 24-pulse Basic Line Modules: 8.5 l
•
The maximum cable lengths between the Braking Module and the braking
resistor depends on the specific plant or system and can be derived from the
condition L/R < 20
μ
s considering the formula L' = L/a for the inductance per
length. The maximum cable length a then is: a < 20
μ
s · R/L'
Example:
For a braking resistor with 9.5
Ω
and an inductance per unit length of
0.25 mH/km, the maximum cable length is 760 m. As a consequence, the
braking resistor can be located less than 380 m away when using a single cable
(routing in both directions). When two cables in parallel are used, the length is
doubled, as the inductance is halved.
