Notes: 1. The forced stop signal is issued for two axes of the servo amplifier. For overall system, apply the emergency stop on the controller side. 2. For details such as setting the servo system controllers, refer to the programming or user's manual of each controller. 3. Connections for the third and following axes are omitted. 4. Up to 64 axes are set with a combination of an axis selection rotary switch (SW1) and auxiliary axis number setting switches (SW2-5 and SW2-6). Note that the number of the connectable axes depends on the controller specifications. 5. Devices can be assigned for DI1-A/B, DI2-A/B and DI3-A/B with controller setting. Refer to the controller instruction manuals for details on setting. 6. This is for sink wiring. Source wiring is also possible. 7. CINP (AND in-position) is assigned to this pin as default. Device for this pin can be changed with [Pr. PD08]. 8. To prevent an unexpected restart of the servo amplifier, create a circuit to turn off EM2 (Forced stop 2) when the main circuit power is turned off.

Be sure to read through Instruction Manual for the actual wiring and use. Use the equipment after you have a full knowledge of the equipment, safety information and instructions.
