Note 1. Use reinforced insulating type for 24 V DC and 48 V DC power supply.
2. For the encoder cable, use of the option cable is recommended. For selecting cables, refer to "Servo Motor Instruction Manual
(Vol. 3)".
3. This circuit is an example of stopping all axes when an alarm occurs. If disabling CALM (AND malfunction) output with the
parameter, configure the circuit which switches off the main circuit power supply after detection of alarm occurrence on the
controller side.
4. This is for the sink I/O interface. For source I/O interface, refer to section 3.8.3.
5. For connecting servo motor power output lines, refer to "Servo Motor Instruction Manual (Vol. 3)". Connecting a wrong axis
may cause a malfunction.
6. The noiseless grounding terminals
of E1 and E2 are connected in the servo amplifier. Be sure to ground from the noiseless
grounding terminal of CNP1 to the grounding terminal
of the cabinet.
7. Configure a circuit to turn off EM2 when the main circuit power is turned off to prevent an unexpected restart of the servo
amplifier.
8. 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.
For 24 V DC power for I/O signal, use power other than 24 V DC power of servo amplifier control circuit power supply.
9. Circuit protectors are required for protection of power supplies, wires, servo amplifiers and others. When not using a circuit
protector, configure an external protective circuit such as a power supply with protection function.
