Appendix 11 Driving On/Off Of Main Circuit Power Supply With Dc Power Supply - Mitsubishi Electric MELSERVO-J4 Series Instruction Manual

Appendix 11
Connection example
The power circuit is common to all capacity type of servo amplifiers. For the signal and wirings not given in this section, refer
to the following.

*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. 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, slow 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.
