Description
Power Module PM240 for Sinamics G120.
PM240 Power Modules feature an integrated brake chopper and are designed for drives without energy recovery capability to the supply. Generator energy produced during braking is converted to heat via externally connected braking resistors.
The PM240 Power Module can be used to couple the DC link of up to 10 Power Modules. This functionality is useful for applications such as safe power-down after power failure or kinetic buffering (the DC link is supplied in generator mode with kinetic load energy so that the DC link voltage can be maintained).
The PM240 Power Module is also designed for safety-oriented applications. In conjunction with a Fail-safe Control Unit, the drive can be turned into a Safety Integrated Drive.
The permissible cable lengths between inverter and motor are limited. Longer cables can be used if output reactors are connected . Line reactors are available for minimizing system perturbations.
Frame size FSA of the PM240 Power Module is available only without integrated line filter to class A. A base filter for compliance with class A is therefore available. A base filter for compliance with class B is available.
Frame sizes FSB and FSC of the PM240 Power Module are available both with and without integrated line filter to class A. For compliance with class B, PM240 Power Modules with integrated line filter to class A must be fitted additionally with a base filter to class B.
Power Modules with integrated line filter to class A are suitable for connection to TN supply systems. Power Modules without integrated
line filter can be connected to grounded (TN, TT) and non-grounded (IT) supply systems.
