TRANSMISSION MODES
POLLED mode
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
CYCLIC mode
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
SYNC mode
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.
PROGRAMMABLE PARAMETERS
Operating
Parameters
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 4096 can be programmed
Total resolution
‘’Max range’’
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.
Preset Value
The preset value is the desired position value, which should be reached at a certain physical position of
the axis
Limit Switch,
Min. and Max
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
CONFIGURATION
The standard configuration is : node number = 32 and Baurate = 125kBaud. These configurations can be modified
with SDO frames. The Baudrate can be modified from 20kBaud to 1MBaud. The node number can de programmed
between 0 and 89.
