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.
NOTICE
Correctly connect peripheral devices. Incorrect installation can cause damage to the drive and connected circuits.
•
Use for sourcing mode
The load impedance changes the voltage level of the pulse train output signal.
