5.2.4 Using the SERVOPACK to Reset the Absolute Encoder
Use the following procedure to reset the absolute encoder with a Digital Operator from a Σ-V
SERVOPACK.
This concludes the operation for setting up the absolute encoder. Turn the power supply OFF
and ON again to reset the SERVOPACK.
When the absolute encoder is reset, the number of turns is reset to 0, which changes the
mechanical reference position. If the machine is operated in this state, unintended operation
could occur resulting in injuries or damage to the machine. Be careful when starting the machine
to ensure that this does not occur.
Refer to the following manual for details.

cations Reference (Manual No.: SIEP S8000000 64)
