F is included in the total capacitance value. If the DC link
capacitance is not sufficient for the use of one or more Braking
Modules, a Capacitor Module can be added to increase the
effective DC link capacitance of the drive line-up.

Braking Modules and braking resistors for chassis format
Braking Modules with a braking power of 25 kW (for frame size
FX) and 50 kW (for frame sizes GX, HX and JX) are available with
匹配机箱格式单元的制动阻力。制动单元
can be connected in parallel to obtain higher braking powers. In
在这种情况下,可以在线模块端安装单元或
Motor Module end.
When a Braking Module is installed in a Basic Line Module of
size GB/GD, the cables supplied for the DC link connection are
太短。在这种情况下,电缆线束套件
6SL3366-2NG00-0AA0 must be ordered to make the Braking
Module connection.
The Braking Module features an electronics interface (X21) with
monitoring function. The braking resistor housing contains a

制动模块和制动电阻要求的计算
•
对于周期持续时间的周期性占空环
≤
90s, the
在这个占空比内制动能力的平均值必须
be defined. The relevant cycle duration must be applied as
the time base.
•
对于周期持续时间的周期性占空环
≥
90s or for
sporadic braking operations, a time interval of 90 s in which
the highest average value occurs must be selected. The 90 s
period must be applied as the time base.
除了平均制动功率,所需的峰值
制动时也必须考虑制动能力
选择单元(制动模块和制动电阻器)。
