Reference: Image of PLC output and waveform (for MELSERVO-J3 Series servo amplifier)
1) Base unit (transistor output (sink output))
a) Connection of PLC to servo amplifier
When a FX
3U Series PLC (sink output) is used, it is connected as shown below.
b) Image of PLC output and output waveform
2) High-speed output special adapter (set to "pulse train + direction")
a) Connection of PLC to servo amplifier
b) Image of PLC output and output waveform
The output waveform shown below is based on the SGA terminal of the high-speed output special
adapter. If the SGB side of the high-speed output special adapter is used, the output waveform will be
that of the SGB terminal.
