Control Techniques SP2401

Siemens 6SN1145-1BB00-0FA1

The SIMODRIVE 611 module 6SN1145-1BB00-0FA1 is an infeed regenerative feedback (IR) unit manufactured by Siemens for closed-loop control. 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

Infeed/regenerative feedback module, regulated:

DC link power PZK ≤ 120 kW

Peak power 175 kW

Charge limit 20000 μF

The Siemens infeed module 6SN1145-1BB00-0FA1 is used to connect the drive group to the line supply.

The DC link receives power through the infeed / regenerative feedback module. The regenerative feedback module, along with the UI and monitoring, provides the electric power supply for any modules that are connected.

The infeed regenerative feedback unit 6SN1145-1BB00-0FA1 does not have any comprehensive overload protection. How do you ensure line protection for your motor? To obtain overload protection, the protection must be provided by the configuration and correct setting of the current values. The current values are set with the control boards.

How does the infeed regenerative feedback (I/R) unit interact with the HFD reactor?

The infeed regenerative feedback (I/R) modules along with the HF/HFD commutating reactors make up the step-up converter (7 kHz). The step-up converter is necessary for controlling the DC link voltage and enabling regenerative feedback.

The SIMODRIVE 611 module 6SN1145-1BB00-0FA1 infeed regenerative feedback (IR) unit module is primarily used for the following three applications:

It is used to assist machines with high dynamic requirements placed on the drives.

It is used where there are frequent braking cycles and high braking energy.

It is used with control cabinet designs optimized for low operating costs.

Is an HFD necessary for the infeed module to operate properly? The HFD line reactor is required for the I/R module to function. This is cyclically short-circuited for an active step-up controller and voltage control to function.

Overvoltage limiting units

Overvoltage limiting modules are available to limit sporadic, transient overvoltages such as ones that can occur as a result of switching operations in the line supply.

Monitoring modules

The monitoring module supplies electronic power for the equipment bus and the central monitoring functions. They create a separate drive group. Usually, the power is supplied by the 3-phase 400-800 V AC line supply. The power supply is also able to be connected to the DC link in case there is a power failure.

Is the monitoring module necessary? The monitoring module is required if a higher number of drive units in the group exceeds the electronics power supply of the infeed module, IR, or UI modules. When using the monitoring module, you can then group drive modules in multiple cabinet compartments or group drive modules in tiers.

Arrangement of infeed module 6SN1145-1BB00-0FA1

How is the infeed module, such as the SIMODRIVE 611 module 6SN1145-1BB00-0FA1 infeed regenerative feedback (IR) unit module, arranged in the drive grouping? The infeed module (IR) along with the UI and monitoring modules are located first in a cabinet on the left.

How are the line supply infeed and drive modules mounted to the mounting panels? Infeed modules drive modules, and commutating reactors have a mounting surface. The mounting surface of these modules has to have a low-resistance connection to the mount.

FAQ: Addressing Common Queries

1. What are the primary applications of the SIMODRIVE 611 module 6SN1145-1BB00-0FA1?

This module is employed in scenarios demanding high dynamics from drives, frequent braking cycles, and energy-efficient control cabinet designs.

2. Is an HFD reactor necessary for the infeed module to operate properly?

Yes, the HFD reactor is essential for the proper functioning of the I/R module, facilitating active step-up control and voltage regulation.

3. Are overvoltage limiting units available for the SIMODRIVE 611 module?

Yes, overvoltage limiting modules are available to mitigate sporadic overvoltages, safeguarding against switching operations in the line supply.

4. Is the monitoring module mandatory for operation?

The monitoring module becomes necessary when the number of drive units exceeds the electronics power supply of the infeed module or UI modules. It allows grouping drive modules efficiently.

5. How is the infeed module arranged in the drive grouping?

The infeed module, alongside UI and monitoring modules, is typically positioned first in the cabinet on the left side.

6. How are the line supply infeed and drive modules mounted to the mounting panels?

Infeed modules, drive modules, and commutating reactors feature mounting surfaces that require low-resistance connections to the mount for secure mounting.
