Notes
1. 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.
2. The shielding does not have to be separate for each output as the
drawing suggests but may be common for all analog signals in the
cable.
3. 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.
4. If the analog equipment on the application side accepts a differential
(preferred) or single-ended signal, the AnGND signal must be
connected to the application ground with a resistor R*. If this resistor is
not included in the equipment itself, install it for example in the
connector at the equipment side of the cable. (For single ended input:
100 Ω, for differential 100 Ω – 100 kΩ).
