Chapter 14 Common Functions
(8) Even if the PLC READY signal [Y0| is turned ON by changing "[Pr.100]
Servo series" from "0: Servo series is not set" to other than "0", the setting
does not become valid. (The axis connecting status remains disconnection.)
(9) The operation cannot be changed to amplifier-less operation when
connected and not connected servo amplifier axes are mixed. Change to
amplifier-less operation when all axes are connected, or disconnect all
axes of the servo amplifier.
(10) The synchronous encoder via servo amplifier cannot be used during
amplifier-less operation mode.
