Functions4-][Funktionsbeschreibung Module Supply

Module supply

][Funktionsbeschreibu ng_Peri ABS SSI-Aus

][Funktionsbeschreibung_Ein ST-ABS SSI

 The module supply provides the module with voltage.

Periphery supply

 The supply for the test pulse output is generated from the periphery

supply. It is galvanically isolated from the periphery supply.

As part of each cycle the module sends a pulse sequence at the test
pulse output (Cl) to the SSI absolute encoder. In turn the encoder trans­mits its position data. The position data is read in at the module's input
(D) (see timing diagram: SSI data transfer).

][Funktionsdiagramm ABS SSI

With the system software the user can set the following values to adapt
the module to the encoder or higher level control system:

 Transmission rate

The frequency of the pulses at the test pulse output (Cl) determines
the transmission rate. The user can adapt the frequency to the encod­er in a range from 62.5 kHz up to 1.5 MHz (see Technical Details).

 Input data length:

The module's input data length must be adjusted to the data length
of the absolute encoder.
The module can process up to 32 Bits. The default is 24 Bits.

 Data format:

The data format in which the module transmits the position data of the
connected absolute encoder to the head module.
– Gray code (default)
–Binary code

The position data is transmitted to the head module via the ST module
bus with 4 Bytes, irrespective of the configured input data length. The
module sends additional status information.

 a: Data transfer begins with a falling edge at the Cl signal.
 b: The first bit is transmitted with the first rising edge from the Cl sig-

nal.

 c: The time up to the second rising edge is the period length T. 1/T is

the signal frequency.

 d: The last rising edge from the Cl signal ends the transfer. The en-

coder acknowledges the end of the transfer with a 0 signal.

5.2 Installing the base module

5.2Installing the base module5200Installing the base module5-][Montage Basismodul

Prerequisite:

 The head module must be installed.
 If the head module does not have an integrated power supply, a sup-

ply voltage module must be installed to the right of the head module.

Please note:

 For mechanical reasons it is not possible to mix base modules with

screw terminals and base modules with cage clamp terminals.

 All contacts should be protected from contamination.
 The mechanics of the base modules are designed for 50 plug in/out

cycles.

Procedure:

 We recommend that you wire up the base modules before inserting

the electronic modules.

 Slot the groove on the base module on to the mounting rail from be-

low [1].

 Push the base module back [2] until you hear it lock into position.
 On the mounting rail, slide the base module to the left until you hear

the two lateral mounting hooks on the adjacent module lock into po­sition [3].

Please note:

 Only insert on to base modules that are already installed.
 Preferably these base modules should be ready wired.
 Electronic modules with outputs may only be inserted and removed

when the load is switched off. Unforeseeable error reactions may be
triggered if modules are inserted and removed under load.

 When an electronic module is plugged into a base module for the first

time, one part of the coding element remains on the electronic mod­ule, while its counterpart is fixed on to the base module. This is how
the base module is coded.

 The mechanics of the electronic modules are designed for 50 plug in/

out cycles.

The electronic module can be hot swapped. The configuration data is re­tained when a module is swapped.

Effects:

 System environment A:

– An ST communication error may occur.

 System environment B:

– While the module is disconnected, the substitute values for the

module's signals/values are used (Valid Bits = FALSE).

– Once the module is reconnected, it is reactivated automatically.

][Verdrahtung ST ABS SSI

 Use twisted pair cables to carry the differential signals (D+/D- and

Cl+/Cl-). This will increase the noise immunity.

Please note:

 Use shielded signal cables with metallic plugs.
 On base modules with C-rail:

– Connect the shield to the terminals on the C-rail.
– Connect the C-rail with low impedance to the functional earth.

 On base modules without C-rail:

– Connect the shield as shown in the terminal configuration section.

The module connects the shield to the mounting rail.

– Connect the mounting rail to the functional earth via an earthing

terminal.

 The supply voltages must be extra low voltages with safe electrical

separation (PELV or SELV) in accordance with VDE 0100, Part 410.

][Verdrahtung Zusatz mit C

 Use copper wiring.
 The terminal configuration as stated on the front plate applies for base

modules with C-rail. The terminal configuration as stated in the tech­nical documentation applies for all other base modules.

6.1.1 Mechanical connection of the base modules

Mechanical connection of the base modules6-][Modulverdrahtung mech

Procedure:

 Use a flat blade screwdriver (DIN 5264-A)!

 Strip the wire back 8 mm.
 If necessary, label the connection level with a colour marker [3].
 Base module with screw terminals:

– Use a screwdriver to loosen the screw on the screw terminal [1]
– Insert the stripped cable into the round fixing hole [2], as far as it

will go.
– Tighten up the screw on the screw terminal.
– Check that the cable is firmly seated.

6.1 General wiring guidelines

 On base modules with screw terminals:

– If you use a multi-strand cable to connect the I/Os, it is recom-

mended that you use ferrules conforming to Parts 1 and 2 of

DIN 46228, 0.14 ... 1.5 mm

sential. To crimp the ferrules you can use crimp pliers (crimp form

A or C) conforming to EN 60947-1, such as the PZ 1.5 or PZ 6.5

from Weidmüller, for example.
– Maximum torque setting: 0.8 Nm

 Use copper wiring.
