App. 6 When Turning On Or Off The Input Power Supply With Dc Power Supply - Mitsubishi MR-JE-10A Instruction Manual

APPENDIX

App. 6 When turning on or off the input power supply with DC power supply

App. 6.1 Connection example
For the signals or wiring that are not described in this section, refer to section 3.1.
Note 1. When using a power supply of 1-phase 200 V AC to 240 V AC for MR-JE-10A to MR-JE-100A, connect the power supply to L1
and L3. Leave L2 open. When using a power supply of 1-phase 200 V AC to 240 V AC for MR-JE-200A, connect the power
supply to L1 and L2. Leave L3 open. MR-JE-300A cannot be used with 1-phase 200 V AC to 240 V AC power supply.
2. Do not use the 24 V DC interface power supply for magnetic contactor. Always use the power supply designed exclusively for
the magnetic contactor.
3. This is for the sink I/O interface. For source I/O interface, refer to section 3.9.3.
4. Controlling the on switch or off switch with DC power supply satisfies the requirements of IEC/EN 60204-1.
5. Configure a circuit to turn off EM2 when the power is turned off to prevent an unexpected restart of the servo amplifier.
6. 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 power supply voltage and operation pattern, bus voltage can decrease. This can
shift the mode to the dynamic brake deceleration during forced stop deceleration. When dynamic brake deceleration is not
required, delay the time to turn off the magnetic contactor.
App. 6.2 Magnetic contactor
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.
