Definitions and Warnings
Components which can be destroyed by electrostatic discharge (ESD)
The board contains components which can be destroyed by electrostatic discharge. These components can be easily destroyed if not carefully handled.
If you have to handle electronic boards, please observe the following:
♦
Electronic boards should only be touched when absolutely necessary.
♦
The human body must be electrically discharged before touching an electronic board.
♦
Boards must not come into contact with highly insulating materials - e.g.
plastic parts, insulated desktops, articles of clothing manufactured from manmade fibers.
♦
Boards must only be placed on conductive surfaces.
♦
Boards and components should only be stored and transported in conductive packaging (e.g. metalized plastic boxes or metal containers).
♦
If the packing material is not conductive, the boards must be wrapped with a conductive packaging material, e.g. conductive foam rubber or household aluminium foil.

SBR - Sensor Board Resolver Description
NOTE
The SBR optional board (Sensor Board Resolver) enables a resolver to be connected to the converter and inverter modules.
The SBR optional board is available in two versions:
♦ SBR1
♦
SBR2
Optional board for connecting up a resolver
Optional board for connecting up a resolver with additional pulse encoder simulation
Connectable resolvers
Temperature sensor
You can connect all standard 2-pole resolvers and resolvers with the pole pair number of the motor to the optional board. Adaptation to the different types of resolvers is effected on the optional board by automatic adjustment of the signal amplitude and the sampling time.
As well as a resolver, you can connect a temperature sensor (either a KTY or a
PTC sensor) to the optional board for monitoring the motor temperature.

SBR - Sensor Board Resolver
Function principle
Description
The position of an exciter coil in the rotor in relation to two stator coils is evaluated in the resolver.
A high-frequency carrier signal (5 to 10 kHz) is injected into the rotor winding of the resolver via a rotary transformer. The high-frequency current flowing in the rotor induces a high-frequency voltage into the two stator coils arranged at right-angles to each other. The amplitude of this voltage depends on the present position of the rotor winding or of the rotor. The envelope curve of the voltage induced into the stator coils is a sine or cosine curve.
On account of the right-angle arrangement of the stator coils, one coil will supply the sine value, and the other coil the cosine value of the present rotor position. Both signals are sensed via A/D transformers.
Subsequently, the unit software calculates the position angle
α from these two signals via trigonometry functions.
The change of the position angle
α
between two sampling times provides the current speed of the motor.

Description
Adjustment
SBR - Sensor Board Resolver
Via a PLL control loop, the SBR optional board is capable of setting the phase position of the exciter signal such that the sine or cosine signal induced in the stator windings of the resolver is always sensed at maximum.
At the same time, the amplitude of the exciter signal is adjusted to the maximum resolution of the internal A/D transformer. This enables the position angle of the stator winding to be sensed with the maximum possible accuracy.

SBR - Sensor Board Resolver Installation
NOTE
If the inverters/converters are ordered with optional functions, the optional boards are already installed in the units when they are delivered.
It is possible to retrofit optional boards and this can be carried out by the user.
For this purpose, there are either three or up to six slots on the basic unit depending on the unit type of construction for mounting the optional boards.
An exact description of installation is included with the relevant basic unit. As the unit has to be removed and opened in order to install optional boards, attention must be paid to the ESD measures. Please refer to the operating instructions of the basic unit in this regard.
Install the SBRx optional board in slot C. The SBRx optional board does not operate in other slots.

Pulse encoder simulation
(only for SBR2)
Connecting-up
At connection X410 you can pick up the signals of the pulse encoder simulation generated on the optional board.
The optional board generates 512 or 1024 pulses alternatively per electrical revolution. In the case of a two-pole resolver the set pulses (512 or 1024) are generated accordingly, in the case of a four-pole resolver twice the number of pulses are generated, and in the case of a six-pole resolver, three times the number of pulses are generated per mechanical resolver revolution.
The simulation signals are available as differential signals according to standard RS 422.
