Note 1. To prevent an electric shock, always connect the protective earth (PE) terminal (marked ) of the servo amplifier to the
protective earth

8. Up to 64 axes of servo amplifiers can be connected. The number of connectable axes depends on the controller you use.
Refer to section 4.3.1 for settin

of axis selection.
9. Make sure to cap the unused CN1B connector.
10. Supply 24 V DC ± 10% for interfaces from outside. Set the total current capacity to 300 mA. 300 mA is the value applicable
when all I/O signals are used. The current capacity can be decreased by reducing the number of I/O points. Refer to section
3.8.2 (1) that gives the current value necessary for the interface. The illustration of the 24 V DC power supply is divided

15. Configure a circuit to turn off EM2 when the main circuit power is turned off to prevent an unexpected restart of the servo
amplifier.
16. When not usin

the STO function, attach the short-circuit connector came with a servo amplifier.
17. When you use a linear servo motor or direct drive motor, use MBR (Electromagnetic brake interlock) for an external brake
mechanism.
