PROGRAMMABLE PARAMETERS

Operating
Parameters

By a remote-transmission-request telegram the connected host calls for the current process value. The
absolute rotary encoder reads the current position value, calculates eventually set-parameters and sends
back the obtained process value by the same identifier

The absolute rotary encoder transmits cyclically - without being called by the host - the current process
value. The cycle time can be programmed in milliseconds for values between 1 ms and 65536 ms

After receiving a sync telegram by the host, the absolute rotary encoder answers with the current process
value. If more than one node number (encoder) shall answer after receiving a sync telegram, the answer
telegrams of the nodes will be received by the host in order of their node numbers. The programming of an
offset-time is not necessary. If a node should not answer after each sync telegram on the CAN network, the
parameter sync counter can be programmed to skip a certain number of sync telegrams before answering
again

This parameter determines the counting direction, in which the output code increases or decreases. As an
important operating parameter the code sequence (complement) can be programmed

Resolution per turn Value between 1 and 8192 can be programmed

Total resolution
‘’Max range’’

Preset Value

Limit Switch,

Min. and Max

This parameter is used to program the desired number of measuring units over the total measuring range.
This value may not exceed the total 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

Two position values can be programmed as limit switches. By reaching these values one bit of the 32 bit
process value is set to high level

Cam One free programmable cam can be set in the total measuring range

INSTALLATION

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 5.5 up to 9 mm

CONFIGURATION

The setting of the node number is achieved by 2 turn-switches in the connection cap. Possible
addresses lie between 0 and 89 whereby every address can only be used once. Inside the encoder
the defined address is increased by one. The connection cap can easily be opened for installation
by removing the two cap screws
A termination resistor is integrated in the connection cap. The resistor must be switched on if the
encoder is connected at the end or at the beginning of the bus
