(3) Connection of manual pulse generator
Manual pulse generators of the voltage-output/open-collector type and
differential-output type can be connected. Both connection methods are different.
(Refer to this section (5).)
When the manual pulse generator is connected to the Q173DPX, it cannot be
connected to the built-in interface in Motion CPU.

(4) Connection of incremental synchronous encoder
Incremental synchronous encoders of the voltage-output/Open-collector type and
differential-output type can be connected. Both connection methods are different.
(Refer to this section (5).)
Serial absolute synchronous encoder not connected to Q173DPX. Then connect
to Q172DEX.
In addition, the usable numbers of synchronous encoders differ depending on the
modules.
The following number of serial absolute synchronous encoders and incremental
synchronous encoders combined can be used.

• Tracking enable signal
Tracking enable signal of Q173DPX is used to start the input from incremental
synchronous encoders in the external input mode for the clutch.
The external input signal of the incremental synchronous encoder is indicated
below.
This signal is used as the input start signal, high-speed reading function or
high-speed input request signal from incremental synchronous encoder.
