*1 For the power supply specifications, refer to the following.
Page 30 Servo amplifier standard specifications
*2 This diagram shows sink I/O interface. For source I/O interface, refer to the following.
Page 118 Source I/O interface
*3 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 (160 ms or less for 5 kW or more). 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.
*4 Configure a circuit to turn off EM2 when the main circuit power is turned off to prevent an unexpected restart of the servo amplifier.
*5 When not using the STO function, attach the short-circuit connector came with a servo amplifier.
*6 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.
*7 Driving the on switch and off switch with the DC power supply meets IEC/EN 60204-1 requirements.
*8 Do not use the 24 V DC interface power supply for the magnetic contactor DC power supply. Always use the power supply designed
exclusively for the magnetic contactor.
*9 If disabling ALM (Malfunction) output with the parameter, configure the power supply circuit which switches off the magnetic contactor
after detection of alarm occurrence on the controller side.
*10 When wires used for L11 and L21 are thinner than wires used for L1, L2, L3, and N-, use a fuse.
