Notes
1. The shielding does not have to be separate for each input as the
drawing suggests but may be common for all analog signals in the
cable.
2. Follow the following cabling instructions:
● Always use a shielded cable.
● The shielding on the NYCe 4000 side of the cable must be
connected to Shield (house connector).
● If the equipment on the application side is metal, connect the shield
to the equipment housing.
3. Connect the NYCe 4000, a power supply or other equipment on a metal
frame or mounting base and make sure there is a galvanic contact.
4. AnGND is connected to the internal system ground: ground MCU, drive
logic, encoder ground, and host PC if the MCU is NY4110 and an
IEEE 1394b cable is used.
5. You can use AnVref as a reference voltage for improved accuracy, for
example for a DAC (if used, in your design).
6. If the analog input source provides a balanced differential signal,
connect the signal wires to the corresponding input pins on the
NYCe 4000 side.
7. If the analog input source provides a balanced differential signal, it may
be desirable to connect a termination resistor between the signal wires
at the NYCe 4000 side. Consult for this the supplier's installation
instructions.
8. If the analog input source provides a single ended signal, connect the
signal wire to the positive input pin on the NYCe 4000 side, and connect
the application ground to the negative input pin and analog ground pin
on the NYCe 4000 side.
