■Point of the setting method
• "Scale measurement mode selection (PA22)" is set to the servo amplifier set by "ABS" or "INC" from the "External
synchronous encoder input" list of the amplifier setting dialog using the Simple Motion Module Setting Function.
• When the servo parameter "Scale measurement mode selection (PA22)" is changed, it is required to switch the power of
servo amplifier off once after the parameter is transferred to the servo amplifier, and then switch it on again.
• If the servo amplifier set by the servo parameter "Scale measurement mode selection (PA22)" does not support the "Scale
measurement mode", "AL.37" (parameter error) will occur in the servo amplifier. Refer to the servo amplifier instruction
manual for details of the servo parameter "Scale measurement mode selection (PA22)".
• The synchronous encoder via servo amplifier can be controlled up to 4. However, there is no restriction for the number of
connections. Therefore, the error check is not executed even when the external synchronous encoders are set more than 4
in the "System Setting" using the Simple Motion Module Setting Function.
• The following information of the synchronous encoder via servo amplifier can be output with the optional data monitor. The
setting details of the optional data monitor for the synchronous encoder information are shown below.

Scale absolute counter
• A serial absolute synchronous encoder Q171ENC-W8 can be used in an incremental system by setting "2_ _ _H" in the
servo parameter "Scale measurement mode selection (PA22)" even if the battery of the servo amplifier is dismounted.
