概述
A Braking Module and the matching external braking resistor are
required to bring drives to a controlled standstill in the event of a
电力故障（例如紧急缩回或紧急停止
类别1）或在短时间内限制直流链路电压
of generator operation. The Braking Module includes the power
电子和相关控制电路。操作过程中，
直流链路电源在外部转换为热损失
braking resistor. Braking Modules function autonomously.
The Braking Module is designed for installation in the PM240
电源模块，框架尺寸FSGX，并使用电源冷却
Module fan. The supply voltage for the electronics is taken from
直流链路。制动模块连接到DC链路
using the busbar sets included in the scope of delivery.
The activation threshold of the Braking Module can be adjusted
通过DIP开关。指定的制动功率值
in the technical specifications apply to the upper activation
threshold.
