*1: The logic of each I/O terminal can be changed by the intelligent function
module switch setting (refer to Section 5.6). (The above example assumes
that all terminals are set to the negative logic.)
In addition, the above example is for connecting to Axis 1. (For the pin layout
when connecting to Axes 2 or 3, refer to "Section 3.5.2 Signal layout for
external device connector".)
*2: These are limit switches for servo amplifier (for stop).
*3: For details of connection, refer to the MR-C series Servo Amplifier Instruction
Manual.
*4: This indicates the distance between the QD72P3C3 and servo amplifier.
Regenerative resistor is an external option.
