PROGRAMMABLE PARAMETERS
The Interbus encoder supports the programmable encoder profiles K1, K2 or K3 of the ENCOM (User group of encoder
manufacturers in the Interbus club). The following parameters can be programmed directly via the INTERBUS network without any
extra devices:
Code sequence
As an operating parameter the code sequence (complement) can be programmed. This
parameter determines whether the output code increases or decreases when the axis is turned
clockwise.
Output steps over number of
revolutions
This parameter defines the number of measuring steps over the number of revolutions described
below.
Number of revolutions
This parameter determines the number of revolutions used to calculate the steps per revolution. For
example: Total resolution=8, Revolutions=2, then the Steps per revolution will be equal to 4. This
value must always be less than the total allowed revolutions (for a multi-turn, 4,096).
Preset value
The preset value is the desired output value for the actual position of the axis. The actual output
value will be set to this preset value.
Zero point displacement
This parameter sets the zero point of the output in relation to the physical zero point position of the
encoder. (same functionality as preset value).
Velocity (Optional)
Optionally, the current rotational velocity of the axis can be output in revolutions per minute.
Read-out parameter values
and temperature (Optional)
Optional all parameter values, certain other information (specified in the manual) and the
temperature value of an additional temperature sensor can be read out via the bus.
Cam functions
Cam functions which are entirely programmable via the bus are integrated in the encoder.
INTERFACE
The rotary encoder is connected by two cables via 9-pin connectors, one as input line,
the other one as output line. Each cable contains both power supply and the bus lines.
To ensure the correct wiring, the input socket on the encoder has pins (male) whereas
the output socket has holes (female). The address of the encoder is derived from its
physical position in the network. The encoder is designed for a remote bus with up to 32
bits of I/O data. In the master (controller) the actual process values occupy one or two
word addresses for profile K1 or K2 and K3, respectively.
