1 General Information
These operating and assembly instructions contain the following topics:
●General functional description
●Basic safety instructions with declaration of the intended use
●Characteristics
●Assembly
●Installation/Commissioning
●Parameterization
●Error causes and remedies
The operating and assembly instructions are supplementary to other documentation, such as
product data sheets, dimension drawings, etc.
The scope of delivery includes the absolute encoder AMP(H) 41, the operating and assembly
instructions and the Software and Support CD.
The operating and assembly instructions may be requested separately.
1.1 Applicability
These operating and assembly instructions apply exclusively for the following measuring
system series with PROFIBUS-DP interface and PROFIsafe profile:
●AMP 41
●AMPH 41
The products are labelled with affixed nameplates and are components of a system.
The following documentation therefore also applies:
●operator’s operating instructions specific to the system,
●and these operating and assembly instructions
1.2 General functional description
The AMP(H) 41 rotary measuring system is a safe and absolute Multi-Turn position measuring
system with PROFIBUS interface and PROFIsafe protocol.
The measuring system has primarily been designed for use in systems that require safe
position detection.
The safety measuring system consists of a redundant, two-channel system, in which optical
and magnetic scanning units are arranged on a drive shaft, designed as a hollow shaft or
solid shaft.

AMP(H)41_MANUAL-en_R11 - 2019-03-28
Absolute Encoder AMP(H)41
1.2.1 Main Features
●PROFIBUS interface with PROFIsafe protocol, for transfer of a safe position and speed
●Quick process data channel via PROFIBUS, not safety-oriented
●Additional incremental interface, not safety-oriented
●Two-channel scanning system, for generation of safe measured data through internal
channel comparison
–Channel 1, master system:
optical Single-Turn scanning via code disk with transmitted light and magnetic Multi-Turn
scanning
–Channel 2, inspection system:
magnetic Single and Multi-Turn scanning
●A common drive shaft
Due to its technology the optical system possesses greater accuracy; therefore it is used as
master system. The data of the master system are unevaluated in the non-safety-oriented
process data channel with normal PROFIBUS protocol, but are made available with a short
cycle time.
The magnetic scanning system serves for the internal safety check. The "safe data" obtained
through two-channel data comparison are packed into the PROFIsafe protocol and also
transmitted to the control via the PROFIBUS.
The incremental interface is derived from the master system and is not evaluated in relation to
safety.
1.2.2 Principle of the safety function
System safety results when:
–Each of the two scanning channels is largely fail-safe thanks to individual diagnostic
measures.
–The measuring system internally compares the positions detected by both channels in two
channels, also determines the speed in two channels and transfers the safe data to the
PROFIBUS in the PROFIsafe protocol, see Fig. 1: System diagram “Black Channel” on
page 13.
–In the event of a failed channel comparison or other errors detected through internal
diagnostic mechanisms, the measuring system switches the PROFIsafe channel into error
state.
–The measuring system initialization and execution of the preset adjustment function are
appropriately verified.
–The control additionally checks whether the obtained position data lie in the position window
expected by the control. Unexpected position data are e.g. position jumps, tracking error
deviations and incorrect direction of travel.
–When errors are detected the control introduces appropriate safety measures defined by the
system manufacturer.
–The system manufacturer ensures, through correct mounting of the measuring system, that
the measuring system is always driven by the axis for measurement and is not overloaded.
–The system manufacturer performs a verified test during commissioning and in the event of
any parameter modification.

2.5 Safety functions of the fail-safe processing unit
The F-Host, to which the measuring system is connected, must perform the following safety
checks.
NOTES!
To enable the correct measures to be taken in the case of an error, the
following applies:
If no safe position can be output due to an error detected by the measuring
system, the PROFIsafe data channel is automatically put into fail-safe status. In
this status so-called "passivated data" are output via PROFIsafe.
See chapter 9.1 "Output of passivated data (substitute values) in case of
error" on page 75.
Passivated data outputs are:
–PROFIsafe data channel: all are set to 0
–PROFIsafe status: error bit 21Device_Fault is set
–PROFIsafe-CRC: valid
Upon receipt of passivated data, the F-Host must put the system into a
safe state. It is only possible to leave this error state by eliminating the
error and then switching the supply voltage off and on again!
The process data channel addressable via PROFIBUS is not necessarily
affected by this. If the internal diagnosis in the master channel does not detect
an error, the process data are still output. However, these data are not safe for
the purposes of a safety standard.

●The system manufacturer must implement suitable design measures, so that
the drive of the measuring system is ensured at all times through the shaft
and mounting of the measuring system (fault exclusion). The specifications of
DIN EN 61800-5-2:2008 "Adjustable speed electrical power drive systems,
Safety requirements - Functional, Table D.16 –Motion and position sensors"
must be observed.
●In general, the requirements and acceptance conditions for the complete
system must be taken into account for mounting.
●The measuring system must be inspected on a regular basis (see below).
Inspections must be recorded in a log book.
As the installation situation is application-dependent, the following notes
are not exhaustive.
●All fastening screws must be secured against unintentional loosening.
All screwed connections must be inspected once a year.
●In case of applications with low operating temperatures, increased values for
the start-up torque result. This fact is to be considered when the assembling
and wave drive is performed.
●After approx. 16 000 - 20 000 hours of operation or higher levels of
continuous load:
Check deep groove ball bearings for noise, running smoothly. Bearings must
be replaced by the manufacturer only.
