*1 Use daisy chain power connectors for CNP1 and CNP2. Do not use the connector set supplied with the servo amplifier.

*2 Connect P+ and D terminals. (factory-wired).
*3 Do not remove dummy pins or wires attached to CNP2 connectors.
*4 If overheating of the simple converter is detected, the state between TH1 and TH2 is open. Configure wiring that turns off the servo-on
command after deceleration to a stop by an enabled servo forced stop, an enabled controller emergency stop, or others simultaneously
with when the main circuit power supply of the simple converter is shut off using a 2a contact relay or the like.
*5 Use the magnetic contactor with an operation delay time (interval between current being applied to the coil until closure of contacts) of
80 ms or less. The bus voltage may drop depending on the main circuit power supply voltage and operation pattern, causing a dynamic
brake deceleration during a forced stop deceleration.
*6 To prevent an unexpected restart of the servo amplifier, configure a circuit to turn off EM2 of the servo amplifier when the main circuit
power supply is turned off.
*7 When using multiple servo amplifiers connected to a common bus, configure a circuit that shuts off the main circuit power supply if an
alarm occurs in any of the servo amplifiers. (Configure a sequence using an I/O module or equivalent equipment. Alternatively, connect
an alarm output contact relay for each servo amplifier in sequence on the coil side of the magnetic contactor to shut off the magnetic
contactor.) In addition, stop commands from the controller simultaneously with the main circuit power supply shutting off.
*8 Install an overcurrent protection device (molded-case circuit breaker, fuse, etc.) to protect the branch circuit.
*9 For the wires between the simple converter and a servo amplifier and between each servo amplifier, twist or bundle them with cable ties
to keep the two wires close to each other. Also, total wiring length from P4/N- of the simple converter to P4/N- of the servo amplifier
should be 5 m or less.
*10 When connecting a linear servo motor that has a thermal protector, add a contact that interlocks with the thermal protector output of the
linear servo motor.
