2.5.4 FX3U Series main unit (Transistor Output)
This section describes the transistor output specifications of the FX3U Series main unit. Please note that the
simultaneous turning-on rate is restricted for the output extension units and the main unit. For details on the
restriction, refer to the following manual.
Refer to the FX
3U Hardware Edition.
For MELSERVO Series amplifiers, use a sink input/sink output type PLC.
Pulse output terminals Y000, Y001, and Y002 are high-speed response output terminals.
To use the positioning instruction, adjust the load current of the NPN open collector to 10 to 100 mA (5 to 24 V DC)
.
