*1 The power factor improving DC reactor cannot be used.
*2 Be sure to connect between P+ and D terminals. (factory-wired) When using the regenerative option, refer to the following.
Page 335 Regenerative options
*3 For the encoder cable, use of the option cable is recommended. For selecting cables, refer to "Servo Motor Instruction Manual (Vol. 3)".
*4 If ALM (Malfunction) output is disabled with the parameter, configure the power supply circuit which switches off the magnetic contactor
after detection of alarm occurrence on the controller side.
*5 This diagram shows sink I/O interface. For source I/O interface, refer to the following.
Page 118 Source I/O interface
*6 For connecting servo motor power wires, refer to "Servo Motor Instruction Manual (Vol. 3)".
*7 Use a magnetic contactor with an operation delay time (interval between current being applied to the coil until closure of contacts) of 80
ms or less. Depending on the main circuit voltage and operation pattern, bus voltage decreases, and that may cause the forced stop
deceleration to shift to the dynamic brake deceleration. When dynamic brake deceleration is not required, delay the time to turn off the
magnetic contactor.
*8 Configure a circuit to turn off EM2 when the main circuit power is turned off to prevent an unexpected restart of the servo amplifier.
*9 When not using the STO function, attach the short-circuit connector came with a servo amplifier.
*10 When wires used for L11 and L21 are thinner than wires used for L1 and L2, use a molded-case circuit breaker.

*11 Connecting a servo motor of the wrong axis to U, V, W, or CN2 of the servo amplifier may cause a malfunction.
*12 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.
