Tab. 6-2: 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. The absolute axis position at this en‐
coder variant is retained by the battery buffering even after switching-off the
voltage. If the motor is disconnected from the batterybos, the information
about absolute axis position gets lost after about 1 minute. It replaces a sepa‐
rate absolute value encoder at the motor.
Details for multiturn signals For using the multiturn option, the buffering memory via a necessary battery
is necessary. Therefore, the following accessory must be used:
