制动单位
制动单位
制动单位are used when the drive needs to absorb
regenerative energy occasionally and briefly, for example
快速停止时(紧急停止)。制动
单元包括制动模块和制动电阻器,
它在外部安装。
Two sizes of braking units are available for the SINAMICS
G150类型A.enclosed drive with braking powers of 100 kW
(150 HP&200 HP,460V)和200千瓦(对于较大的460 V.
and 575V units). For higher braking powers, braking units
may be connected in parallel for larger drives (on request,
not for all ratings).
热触点,可以集成到驱动器中
alarm and shutdown sequence, is installed in the braking
电阻监测。
确定所需的制动单元和制动电阻器
• For periodic duty cycles with a load duration of ≤ 90 s, the
该占空比内的平均制动功率值必须是
决定。相关期间应用作
时基。
•对于负载持续时间的定期占空比≥90秒或
对于零星制动操作,90秒的时间段
应该选择哪个最大的平均值。
A 90 s period should be set as the time base.
When determining the required braking unit rating (braking
module and braking resistor), consider both the mean
制动功率值和所需的峰值制动功率。

Calculating the P20 power
To reduce the voltage stress on the motor and drive, the
response threshold at which the braking unit is activated
and the DC bus voltage generated can be reduced. For
example, the DC bus voltage for the drives in the voltage
range from 380 V to 480 V can be reduced from 774 V to
673 V. This also reduces the possible peak power. A factor
1.06,应该使用1.06倍而不是0.8倍。
制动模块的开/关状态由其控制
a 2-point controller. The respective response thresholds are
shown in the following table:
