Control I/O Connections
This section gives information about the settings for the listed control circuit I/O signals.
•
MFDI (terminals S1 to S8)
•
Pulse train output (terminal MP)
•
MFAI (terminals A1 to A3)
•
PTC input (terminal A3)
•
MFAO (terminals FM, AM)
•
MEMOBUS/Modbus communications (terminals D+, D-, AC)
■
Pulse Train Output
You can use pulse train monitor output terminal MP for sourcing mode or for sinking mode.
•
Use for sourcing mode
The load impedance changes the voltage level of the pulse train output signal.
