No power supply
Encoder is ready for operation but it has not received any configuration data after
power on.
Possible causes: address setting incorrect, Bus lines not connected correctly
Parameter or configuration error. The encoder receives configuration or parameter da
incorrect length or inconsistent data
Possible cause: parameter value “total measuring range” too high
The encoder is ready for operation but not addressed by the master
(e.g. incorrect address in configuration).
Encoder has not received any data for a longer period (about 40 sec.)
Possible cause: bus line has been interrupted

PROGRAMMABLE PARAMETERS
The Profibus-DP interface supports CLASS 1 and CLASS 2 functionality according to the encoder profile . In addition to these
functions the GSD-file supports further features, for example software limit switches. Further more, the following encoder parameters
can be programmed directly via the Profibus-DP network without any extra device
This parameter counting direction defines whether the output code increases or decreases
when the shaft rotates clockwise.
The parameter ‘resolution per revolution’ is used to program the desired number of steps per
revolution. Each value between 1 and the physical resolution per revolution can be
programmed
This parameter is used to program the desired number of measuring units over the total
measuring range. This value may not exceed the total physical resolution of the absolute rotary
encoder
The preset value is the desired position value, which should be reached at a certain physical
position of the axis. The position value is set to the desired process value by the parameter preset
The implemented software can additionally deliver the current velocity. This value is transmitted
in binary code, 16 Bit, in addition to the process value
It is possible to choose between four different units: steps per 10 ms, per 100 ms, per 1000 ms and
revolutions per minute
Two software limit switches can be set. If the position value falls below the lower or exceeds the
higher limit switch, a status bit in the process value is set
A special mode is available for commissioning phase of the device. This makes it possible to
change parameters while the encoder is in data exchange mode

INTERFACE
The rotary encoder is connected by two or three cables, depending on whether the power supply is
integrated into the bus cable or connected separately. If the power supply is integrated into the bus
cable one of the cable glands can be fitted with a plug. The cable glands are suitable for cable
diameters from 6.5 up to 9 mm
The Profibus-DP device address is set by user-friendly rotary switches in the connection cap. Allowed
addresses are between 1 and 99, each can only be used once. The connection cap can easily be
opened for installation by removing the two cap screws
Termination resistors are integrated in the connection cap. These must be switched on if the encoder is
connected at the end or the beginning of the bus
