Note 1. Assign DB (Dynamic brake interlock) in [Pr. PD23] to [Pr. PD26] and [Pr. PD28].
2. Refer to section 1.3 for the power supply specifications.
3. 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. Turn off EM2 when the main power circuit power supply is off.
5. 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.
6. Between P3 and P4 is connected by default. When using the power factor improving DC reactor, remove the short bar
between P3 and P4. Refer to section 11.11 for details. Additionally, a power factor improving DC reactor and power factor
improving AC reactor cannot be used simultaneously.
