在版本10_055中引入了旁路功能。通常不使用；然而，它可以设置在两种不同的ent模式中，即模式1和模式2。旁路功能需要一个额外的远程I/O（客舱I/O）。

控制系统模块DARA之后的第一个客舱I/O具有以下I/O列表：

DO 1：关闭旁路接触器KA（向上，沿A方向行驶）

DO 2：关闭旁路接触器KB（下部超同步，沿B方向行驶）

DO 3：打开机械。制动器1，下降后可能需要它来停止重载

DO 4：打开机械。制动器2，下降后可能需要它来停止重载

控制系统模块DARA之后的第二个座舱I/O连接到主开关，是可选的。

然而，实际上必须用于旁路模式2，重旁路，因为该模式被用作

宏和宏选择需要主开关的Cabin I/O。

旁路模式1用于减少电气室或自由隔间内的损耗。

当控制条件下的晶闸管桥已经处于完全导通状态时，向

电机，桥可以与两个接触器KA或KB中的一个短路。

主要目的是使用此功能，而不是为独立的隔间安装主动冷却系统。与有源空调单元相比，两个接触器将大大减少未来的维护。

由于KA和KB是在没有电流的情况下运行的，因此可以通过热方式进行选择。没有理由考虑KA和KB的紧急制动能力。

The bypass feature was introduced in version 10_055. Not usually used; However, it can be set in two different ent modes, mode 1 and Mode 2. The bypass function requires an additional remote I/O (cabin I/O).

The first cabin I/O after the control system module DARA has the following I/O list:

DO 1: Turn off bypass contactor KA (up, drive in direction A)

DO 2: Turn off the bypass contactor KB (the lower part is super synchronized and travel in direction B)

DO 3: Turn on the machine. Brake 1, which may be needed to stop heavy loading after dropping

DO 4: Turn on the machine. Brake 2, after dropping it may be needed to stop the heavy load

A second cockpit I/O after the control system module DARA is connected to the main switch and is optional.

However, it must actually be used for bypass mode 2, heavy bypass, as the mode is used

Macros and macros select the Cabin I/O that requires a master switch.

Bypass mode 1 is used to reduce losses in electrical chambers or free compartments.

When the thyristor bridge under the control condition has been in a fully switched on state, the direction

For the motor, the bridge can be short-circuited with one of the two contactors KA or KB.

The main purpose is to use this function rather than to install an active cooling system for separate compartments. Two contactors will significantly reduce future maintenance compared to active air conditioning units.

Since KA and KB are operated without current, they can be selected by thermal means. There is no reason to consider the emergency braking capabilities of KA and KB.
