Tab. 6-1: Encoder data
Singleturn absolute value encoder The singleturn absolute value encoder serves for absolute indirect position
detection within 1 motor revolution. For this encoder variant, the absolute axis
position gets lost after switching-off the voltage.
Multiturn absolute value encoder The multiturn absolute value encoder serves for absolute indirect position de‐
tection within 65536 motor revolutions. It replaces a separate absolute value
encoder at the motor. The absolute axis position at this encoder variant is re‐
tained by the battery buffering even after switching-off the voltage. If the mo‐
tor is disconnected from the batterybos, the information about absolute axis
position gets lost after about 1 minute.
Details for multiturn signals For using the multiturn option, the buffering memory via a necessary battery
is necessary. Therefore, the following accessory is available:
