If the absolute encoder is powered with the NYCe 4000 encoder power
supply source, the NYCe 4000 software may generate the error message
"Encoder Battery Warning" or "MSM system down" every start-up after
power-on of the 24V System power supply.
A power supply voltage must always be connected to Battery+
and Battery–. If no power supply voltage is connected, the
encoder will return an error.
For proper use, you can choose between two power supply sources to
connect to Battery+ and Battery–.
● External battery: the encoder always returns an absolute position, even
when system power is switched off.
● Enc5V: the encoder works properly, but when system power is switched
off, the absolute position is lost.
Follow these 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.
