Siemens 6SE7035-1EJ84-1BH0 ABO Normalizing Module

Key Features & Benefits

Technical Specifications

What Does an ABO Normalizing Module Do?

In a SIMOVERT MASTERDRIVES system, the drive control board must know the actual motor current and DC link voltage at every operating moment. This information is used to calculate the correct gate signals for the IGBT power modules — the foundation of vector control.

The ABO Normalizing Module is the hardware that performs this critical signal scaling function:

1. Signal Acquisition: Current transducers and voltage measurement circuits in the power stage produce signals proportional to actual current and voltage

2. Signal Scaling: The ABO module contains gain-setting components that convert these raw signals into the standardized range expected by the control board

3. Drive Regulation: The control board receives normalized signals and accurately regulates motor current and voltage

Without a properly functioning normalizing module, the drive cannot accurately regulate motor current and will fault on overcurrent or measurement errors.

Compatibility

The 6SE7035-1EJ84-1BH0 is specifically matched to SIMOVERT MASTERDRIVES units operating at:

• Voltage Class: 380–460V AC / 510–620V DC

• Current Rating: 146A

Important: Installing a normalizing module with a different voltage or current rating will result in incorrect scaling, causing drive faults or, in the worst case, incorrect current control.

Applications

• Heavy Machinery – Drives for large industrial equipment

• Conveyor Systems – Material handling and production lines

• Production Lines – Manufacturing and processing facilities

• Energy & Utilities – Power generation and distribution systems

FAQ

Q1: What is the function of the ABO Normalizing Module?

The ABO Normalizing Module scales and normalizes current and voltage measurement signals from the power stage, converting raw transducer signals into the standardized range expected by the drive's control electronics. This ensures accurate motor current regulation.

Q2: What is the difference between ABO and ABI modules?

ABO modules handle the output current normalization path, while ABI modules handle input-side measurements. Both types are specific to the voltage and current rating of the drive they serve.

Q3: Can I use a different normalizing module with a different current rating?

No. Installing a module with a different voltage or current rating will result in incorrect scaling, causing drive faults or incorrect current control. The 6SE7035-1EJ84-1BH0 is specifically matched to 380–460V AC / 510–620V DC drives with 146A current rating.

Q4: What happens if the normalizing module fails?

Without a properly functioning normalizing module, the drive cannot accurately regulate motor current and will fault on overcurrent or measurement errors.

Q5: Is this module still in production?

The ABO normalizing module series has been discontinued by Siemens since June 2011. Current market supply comes from excess stock, units removed from service, or refurbished modules. However, drives using this module continue to operate in industrial plants worldwide, making this an active spare parts category.

Q6: What is the warranty and condition of the product?

This is a spare part available in new (excess stock), refurbished, or repaired condition. Please contact us for specific condition and warranty information for your order.
