3.2 I/O signal connection example
Consider 15 ms or shorter delay time from input (DI1A to DI6A and DI1B to DI6B) to output (DO1A to DO4A
and DO1B to DO4B) when connecting cascade.
For connection examples of servo amplifiers, refer to each servo amplifier instruction manual.

Note 1. Separate all the external wires by two types, CN10A and CN10B.
2. Assign each input device to the following combinations of connector and pin. For details of each device, refer to section 4.4.1
and 4.4.2.

3. Supply 24 V DC ± 10% to interfaces from outside. When all the I/O points are used, the required current capacity is 0.8 A in
total. The current capacity can be decreased by reducing the number of I/O points. Refer to section 3.3 that gives the current
value necessary for the interface. The illustration of the 24 V DC power supply is divided between input signal and output
signal for convenience. However, they can be configured by one.
