Siemens 6SN1145-1BB00-0EA1 Overview

The 6SN11451BB000EA1 is an infeed module manufactured by Siemens for use with automation drive systems. The Siemens infeed module 6SN11451BB000EA1 is configured within the SIMODRIVE 611 digital drive converter system. Other modules that work with the SIMODRIVE 611 system are the control units, power modules, line supply connectors, and motors. These products are manufactured in Germany and are designed for Automotive, aerospace, power generation, and electronics usage. They come with a 2-year warranty from MRO Electric. We also carry AC Motors from other manufacturers such as FANUC and Yaskawa.

Features of the Siemens 6SN11451BB000EA1

How is the Siemens 6SN11451BB000EA1 infeed module employed within the drive system? In general, the infeed module connects the drive group to the line supply. The I/R modules (Infeed or regenerative) is used to input power to the DC link.  The UI (unregulated infeed) is also used to input power to the DC link. Along with the monitoring module, both the infeed/regenerative and the unregulated modules provide connected modules with the electronics power supply.

Does the infeed module provide overload protection for your drive system? The infeed module has no overload protection for the drive system. To overcome this, overload protection must be configured, and control boards must have appropriate current values set.

I/R modules and HF/HFD commutating reactors are two modules that make up the step–up converter (7 kHz). The step-up converter is used for controlling the DC link voltage. It is also used for enabling regenerative feedback. 

What applications are the I/R module used for? The I/R module is used for the three following applications: 1) High-dynamic machine requirements -placed on the drives 2) Frequent braking cycles/high braking energy 3) Control cabinet designs made for low operating costs. The HFD line reactor is necessary for proper I/R function. 

Arrangement of the SIMODRIVE infeed module 6SN11451BB000EA1

The I/R module along with the UI and monitoring module belong to the left as the first module in a drive grouping. Infeed modules, commutating reactors as well as line filters are to be mounted to the mounting panel through a low-resistance connection such as galvanized plates and panels.

To meet with the CE specifications regarding the voltage limit values for radio interference, line filter modules and shielded cables are available.  When using shielded power cables, a shield terminal plate is used to meet EMC guidelines.

Description of the Siemens infeed module

The infeed module includes a relay contact NC contact and a ready signal NO contact. The relay contact for group signal I2t and motor over temperature for pulse enable, enable voltage, and drive enable. The reference voltage is below for potential for enable: P24, P15, N15, N24, m and reset. Enable voltage, set up operation, contactor energization, start, signaling contact, and line contactor. The next section of the infeed module includes the Enable signal for internal line contactor followed by the signaling contact start inhibit (NC contact). DC link power supply for buffering power failures and three connections for external infeed for the electronics power supply are the next part by the equipment bus.

The LED display indicates with either red, green, or yellow to signal such things as electronics power supply faulted, device readiness, voltage faulted, and DC link overvoltage.
