Product Introduction

6SE7036-0EF85-0EA0

Spare parts* Control module and preload module PET1 with initial phase angle variation for feeder units Type E 380-480V three-phase AC, 50/60Hz Self-commutated feeder/regenerative feeder units (with IGBTs in feed and regenerative feedback directions) provide adjustable DC link voltage. This means that the connected motor modules can be decoupled from the supply voltage. Supply voltage fluctuations within the permissible voltage error have no effect on the motor voltage. The adjustable line modules are designed for connection to neutral-grounded (T, TT) and ungrounded (IT) supply systems.

The DC link is precharged via an integrated precharging resistor:

For operation with active rectifiers, suitable active filter units must be used.

Design

The Active Line Modules in booksize format have the following standard interfaces:

1 power supply connection via screw terminals

1 24" DC electronics power supply connection via 24V terminal adapter (in the scope of delivery)

1 DC link connection via integrated DC link busbar

3 DRIECLiQ sockets

2 PE (protective earth) connections

The status of the Active Line Module (active line) is indicated by two multi-color LEDs:

The shield of the supply line can be connected to the integrated shield connection plate of the Active Line Module with a width of 100 mm via the connection plate, via a shield connection terminal or hose clamp. For example, the KLBU4 type from Weidmuller. The shield connection terminal cannot be used for strain relief of the conductors. For 150 mm, 200 mm and 300 mm mm wide modules, a shielded terminal block is also available.

In principle, all single and double motor modules can be operated on basic input modules, intelligent input modules or adjustable input modules with the appropriate voltage range.

(Only for Active Line Modules with cooling plate)

Overview With its separate power supply and control unit, the SINAMICS S120 drive system is perfectly suited to a wide range of drive tasks. The control unit is selected according to the number of drives to be controlled and the required performance level, while the power supply must be rated to meet the energy requirements of the system. The connection between the control unit and the power supply is very simple using the digital system interface DRIE-CLiQ.

The following drive units are available:

Power supply module

Basic power module

Regenerative rectifier (only air-cooled)

Active Line Module

Active Line Module

The Active Line Module supplies power and returns regenerative energy to the supply system. Braking Modules and braking resistors are only required if the drive system needs to be decelerated after a power failure (i.e. energy cannot be stored). Compared to basic rectifiers and regenerative rectifiers, active rectifiers generate a regulated DC voltage that remains stable within the permissible fluctuation range of the supply voltage regardless of changes in the grid voltage. Active rectifiers in combination with active filters draw nearly sinusoidal currents from the supply system. Hardly any harmonics are generated. The total harmonic distortion factor TID(I) of the current and the total harmonic distortion factor THD(0) of the voltage are typically in the range of about 3 %. They meet the strict limit values of IEEE 519 (2014). All components required for operating the active rectifier are integrated in the active filter. To ensure compliance with The c2 limit values specified in E61800-3 can be installed with a line filter. Motor module

A DC voltage circuit and a frequency converter for powering the motor are integrated in the rectifier cabinet. The motor module is designed for multi-axis drive systems and is controlled by a cU320-2 or SIMOTION D control unit. The inverters are interconnected via the DC busbar.

One or more inverters obtain power for the motor via the DC circuit. Synchronous motors and induction motors can be driven.

Since multiple motor modules share the same DC link, they can exchange energy with each other, that is, if a motor module running in generator mode generates electrical energy, the electrical energy can be used by another motor module running in motor mode. The DC bus of the intermediate circuit is powered by the rectifier.

The control unit is used for intelligent control of multi-machine drive systems. It is equipped with relevant I/0 and the interface for communication with the host control system. Various control units have different functions and different performance levels.

System components

The structure of the drive system can be built by selecting a control unit plus a frequency converter or a rectifier plus an inverter. Other system components can be selected as needed

These system components are:

Line-side switching components, such as line reactors and line filters

DC link components such as brake modules and brake resistors

Output-side components, such as output reactors, iv/dt+VL and sine wave filters

Additional system components such as terminal modules, operator panels and communication boards

Encoder system interface for connecting various encoders to SIHNTCS S120

DRIVE-CLi9 - digital interface between all components

SINAIICS S120 components, including motors and encoders, are equipped with the high-performance DRIVE-CLiQ system interface. For example, the line and motor modules are connected to the control unit - the terminal modules and encoder modules are connected to the drive system via DRIVE-CLQ - simple and effective. Also equipped with

Motors with this interface can be directly connected to the drive. For motors from other manufacturers or retrofit applications, converter modules (sensor modules) are available to convert conventional encoder signals to DRIVE-CLIQ.

 

The electrical gold plate contains all the technical data relevant to the specific component. In addition to the technical data, the gold plate also contains the logistic data (manufacturer D, order number and ID). This data can be called up electronically on site or remotely. Therefore, all components used in the machine can always be identified, which makes service work easier. Painted modules

The following drive cabinets are equipped with coated modules as standard:

Module

Booksize

Chassis drive cabinet

Controls

Sensor modules

Terminal modules

Advanced operator panel (A0P30)

The component coating protects the sensitive components in the s components from harmful gases, dust and moisture. Nickel-plated busbars

All copper busbars in the drive are nickel-plated for weather resistance. It is also not necessary to clean the contacts on the customer terminals, as is done with bare copper connectors.

Note:

For some options, for technical reasons, certain sections of the copper busbars cannot be nickel-plated.
