Notes
1. 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.
2. When switching off the power of the encoder the software behavior is as
follows.
●
A power loss error is generated on the axis.
●
The axis will go to the error state and be set 'not homed'.
To recover from this situation, you must switch on the encoder power,
reset and home the axis.
3. EncGND is connected to the internal system ground, which is ground
MCU, drive logic, analog I/O, and host PC if the MCU is NY4110 and an
IEEE 1394b cable is used.
For proper use, this ground may not be connected to motor or digital I/O
ground.
