Note 1. For 1-phase 200 V AC to 240 V AC of MR-JE-10B to MR-JE-100B, connect the power supply to L1 and L3. Leave L2 open.
For 1-phase 200 V AC to 240 V AC of MR-JE-200B, connect the power supply to L1 and L2. Leave L3 open. MR-JE-300B is
not applicable to 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 diagram shows sink I/O interface. For source I/O interface, refer to section 3.8.3.
4. Controlling the on switch or off switch with DC power supply satisfies the requirements of IEC/EN 60204-1.
5. Configure the power supply circuit that turns off the magnetic contactor after an alarm occurs on the controller side.
6. Configure a circuit to turn off EM2 when the power is turned off to prevent an unexpected restart of the servo amplifier.
7. Use a magnetic contactor with an operation delay time (interval since a current is applied to the coil until the contact closes) of
80 ms or shorter. 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,
slow the time to turn off the magnetic contactor.
App. 7.2 Magnetic contactor
Use a magnetic contactor with an operation delay time (interval since a current is applied to the coil until the
contact closes) of 80 ms or shorter.
