2.5.2 FX3UC Series main unit (Transistor Output)
This section describes the transistor output specifications of the FX3UC Series main unit. Note that the
simultaneous turning-on rate is restricted for the output extension units and the main unit. For details on this
restriction, refer to the following manual:
For MELSERVO Series amplifiers, use a sink input/sink output type PLC.
→ Refer to the FX
3UC Hardware Edition.
*1. The FX
3UC-32MT-LT(-2) uses the display module for monitoring.
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 24V DC)
.
1. Sink internal output circuit
*2. To ground the unit, refer to the servo amplifier (drive unit) manual. If the grounding method is not
specified, carry out class-D grounding.
