Parameter description
Alarm signals
Attribute 83 supplies the alarm signals. An alarm is set when the encoder has recognized a status which can
lead to an incorrect encoder position. As soon as an alarm status is detected, the relevant bit is set to logic
high. The alarm is reset automatically after 2.5 seconds. The alarm flag bit (attr. 85) is also set with each
alarm.


Warning messages
Warnings are signalled by the encoder when internal encoder parameters are out of tolerance. In contrast to
alarm signals, warnings do not indicate an incorrect position. Warnings are reset as soon as the parameter
which was out of tolerance resumes a correct value. The warning flag bit (attr. 88) is also set with each
warning.


Offset value
Attribute 91 contains the parameter offset value. The offset value is calculated within the preset function and
shifts the position value by the calculated value. The preset function is used after the scaling function. The
offset value is not saved in the non-volatile memory until the "Save" service is activated.


Encoder type
Encoder type = 01: Absolute encoder, singleturn
Encoder type = 02: Absolute encoder, multiturn


General services
The encoder position object supports the following services
