• The servo amplifier axis set as
synchronous encoder via servo amplifier
is not supported with scale measurement
mode.
• In system construction, the unset up
servo amplifier axis is set as the
synchronous encoder via servo amplifier.
• In system construction, the axis set to
"Invalid" at the external synchronization
encoder input is set as the synchronous
encoder via servo amplifier.
