指示灯的含义 见附图：
1、y灯一直亮红灯，bf灯不亮？？
当前存在一个故障
2、PN口未插网线，两个link灯均亮绿灯，网络不通，搜索不到设备？
设备正在建立通讯
3、a.CU250S-2PN没有初始IP，需要分配 ，和S120不一样。
b.使用博图进行1200与CU250S-2PN的组态，将CU250S-2PN做现场分布设备，不使用Startdrive进行调试，使用starter调试，在网络组态中对CU250S-2PN的IP进行分配。
发现如果断开1200与CU250S-2PN的链接则CU250S-2PN分配的IP失效，IP回到0.0.0.0 链接上1200则IP恢复，猜测该IP分配需要S7网络链接做支持。
如果使用starter进行IP的分配则不会出现上述现象，IP固定有效。
PM240‑2 Power Modules – 0.55 kW to 250 kW (0.75 hp to 400 hp), IP20 degree of protection
PM240‑2 Power Modules, frame sizes FSA to FSG (with Control Unit and Operator Panel)
The PM240‑2 Power Modules are based on a new hardware platform. This permits an increase in power density.
Furthermore, the PM240-2 Power Module is also suitable for use in safety-oriented applications. In conjunction with a fail-safe Control Unit, the drive can be transformed into a Safety Integrated Drive (see section Control Units).
The PM240‑2 Power Modules in frame sizes FSA to FSF are available both with and without an integrated line filter class A of compact design for 200 V, 400 V and 690 V line voltages (except PM240‑2 frame sizes FSD to FSF: 200 V). The PM240‑2 Power Modules in frame size FSG are available with an integrated line filter Category C3 of compact design for 400 V and 690 V line voltages, also with integrated line filter Category C2 for a line voltage of 400 V. In addition, a DC link reactor is integrated in the PM240‑2 Power Modules, frame sizes FSD to FSG, and therefore no line reactor is required.
The PM240-2 Power Modules with integrated line filter class A are suitable for connection to TN supply systems. Power Modules without integrated line filter can be connected to grounded TN/TT systems and non-grounded IT systems.
The PM240‑2 Power Module has an integrated braking chopper. In generating mode, the excess energy of the DC link can be dissipated by means of an optional braking resistor.
The permissible cable lengths between converter and motor are limited (for max. permissible cable lengths, see Integration). Longer cables can be used if output reactors are connected (see section Load-side power components).
Shield plates and shield connection kits are available for use in the wiring installation of Control Units and Power Modules to ensure that it complies with EMC guidelines.
For more information, see Shield connection kits for Control Units and Power Modules in section Supplementary system components.
