(e) Only axis that the incremental synchronous encoder (manual pulse
generator) is set as drive module can be used in this mode. When an
absolute synchronous encoder is set as the drive module, it cannot be used.
(f) A synchronous encoder, external input and external input mode clutch can
be set in only 1:1 ratio.
The relationship between the synchronous encoder and external input is
shown in the table below.
