Switches and Jumpers on the Terminal Board

The terminal board has switches to adapt the drive I/Os to the external control signals as shown in
Set the switches to select the functions for each terminal.

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.
Note:
Use the formula in Figure 10.12
