Parameter Significance
Alarm signals
Attribute 83 provides the alarm signals. An alarm is set as soon as the encoder is recognizing a status that
may lead to a wrong encoder position. Upon recognising the alarm status, the relevant bit is set to logically
high.
The alarm is automatically reset after 2.5 s. The alarm flagbit (attribute 85) is also set with every alarm.
Warning signals
The encoder will transmit warning signals upon the internal encoder parameters being beyond the
tolerances. Contrary to alarm signals warning signals do not indicate a wrong position. Warnings are being
reset as soon as the parameter that was beyond the tolerances turns into a correct value again. The Warn-
Flagbit (attribute 88) is also set with every warning.
Offset
Attribute 91 comprises the parameter offset value. The offset value is calculated within the preset function
and will shift the position value by the calculated value. The preset function is applied after the scaling
function.
The offset value is not stored into the non-volatile memory until the service “save” is carried out.
Encoder type
Encoder type = 01: absolute encoder singleturn
Encoder type = 02: absolute encoder multiturn
General services
The Encoder Position Object supports the following services:
Code Service Significance
0Eh Get_Attribute_Single Provides the contents of a selected attribute
10h Set_Attribute_Single Changes the value of a selected attribute.
The new value is not yet (!) stored into the non-volatile memory
05h Reset Reset of all parameters to default
15h Restore Restores all parameters of the non-volatile memory
16h Save Saves all parameters in the non-volatile memory to be restored
again after mains off/on.
