PM250 Power Modules – 7.5 kW to 90 kW (10 hp to 125 hp), IP20 degree of protection
PM250 Power Modules, frame sizes FSC to FSF
PM250 Power Modules are suitable for a large number of applications in general mechanical engineering. Any braking energy is directly fed back into the line supply (four-quadrant applications – a braking chopper is not required).
The PM250 Power Module features an absolutely unique technology – Efficient Infeed Technology. This feature provides the ability to feed energy back into the supply system in the generator mode (electronic braking) so that the energy is not converted into heat in a braking resistor. This saves space in the control cabinet. The time-consuming process of dimensioning the braking resistor and the expense of the extra wiring are eliminated. Furthermore, heat losses in the control cabinet are reduced.
Further, the innovative circuit design reduces the line harmonics. There is no need to use an optional line reactor at the supply infeed. This saves space and costs for engineering and procurement.
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).
Frame sizes FSD to FSF of the PM250 Power Modules are available both with as well as without integrated line filter class A.
For frame size FSC of the PM250 Power Module with an integrated line filter class A, an additional base filter of class B is available for achieving class B (see section Line-side components).
The PM250 Power Module is also designed for 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 PM250 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.
Note:
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.

PLC通过报文IO地址直接控制G120X PN
此种控制方式无需专用的程序块，直接给定速度。G120X使用标准报文1，项目及网络配置步骤与方法一相同。通过对输出的个控制字进行驱动器的起停控制、第二个控制字可以指定电机运行的速度。
G120X的输出地址可从设备视图中查看：
在OB1中调用MOVE命令，发送对驱动的控制字及速度给定：
1. 通过个控制字进行驱动器的起停控制（先发送16#047E，再发送16#047F）
2. 通过第二个控制字可以指定电机运行的速度（十六进制16#4000，即十进制的16384对应 p2000 速度参数值）
例如，G120X PN的p2000=3000rpm，如果SpeedSetpoint设置为十进制的8192（即十六进制的16#2000），则表示速度给定1500rpm。
