NGM EVO USER GUIDE
8.2 Channels ENCODER on NGMsX Expansion
The NGMsX can use TWO channels ENCODER LINE DRIVE up to 500 Khz for channel.
The encoder (or optical line) must be connected with a shielded cable, to prevents electromagnetic
interference . It's also recommended to have separated cable for each encoder and put far away the
connection by interferences sources (inverters,high voltage cable, AC motors, ecc.).
NGIO is ready to use LINE-DRIVE encoders, also supplies the +5Vdc source voltage. It can't be used with PUSH-
PULL or OPEN-COLLECTOR encoders.
In case of motor-drives encoder simulation, is not necessary to connect the Vdc supply, but only the GND.
