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 wasted 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 cost for engineering and procurement. The permissible cable lengths between inverter and motor are limited (for max. Permissible cable lengths, see Integration). Longer cable 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 power 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.
