• Set the following in synchronous encoder axis setting for the synchronous encoder axis 1 on the synchronous encoder axis
parameter screen.
Setting item
[Pr.320] Synchronous encoder axis type
Connected Servo Amplifier Axis No.
[Motion Control Parameter]  [Synchronous Control Parameter]  [Input Axis Parameter]  [Synchronous Encoder
Axis Parameter]
Window
• Set servo parameter "Function selection C-8 (Load-side encoder communication method)" of servo amplifier 3 to "1: Four-
wire type".
• Set the axis No. (1 to 32) set in the amplifier setting for connected servo amplifier axis No.
• Turn ON the Multiple CPU system's and servo amplifier's power supply again to validate the set parameter
settings in the servo amplifier.
■Restrictions
• When optional data monitor is set to a servo amplifier axis selected as "101: Via servo amplifier" by "[Pr.320] Synchronous
encoder axis type", set the number of communication data points so that the total comes to 2 points or less per axis.
• When servo error (AL.25, AL.70, AL.71, AL.72) occurs in a servo amplifier axis selected as "101: Via servo amplifier" by
"[Pr.320] Synchronous encoder axis type", the servo amplifier axis is in a servo OFF state.
• The following cases are minor errors (error code: 1BAAH)
• When the servo amplifier axis selected as "101: Via servo amplifier" by "[Pr.320] Synchronous encoder axis type" does not support synchronous encoder via
servo amplifier.
• When a servo amplifier axis which has not been set by amplifier setting is set as the connected servo amplifier axis No. for the synchronous encoder via servo
amplifier.
• When a servo amplifier axis which has "External synchronous encoder input" set to "Invalid" in the amplifier setting is set as the connected servo amplifier
axis No. for the synchronous encoder via servo amplifier.
• When an incremental scale is connected to a servo amplifier which has "External synchronous encoder input" set to "ABS",
a servo error (AL.37) occurs, and the connected scale cannot be used as a synchronous encoder.
• When "Amplifier operation mode" is set to "Fully closed" for a servo amplifier axis that has "External synchronous encoder
input" set to "ABS", or "INC", a servo error (AL.37) occurs.
