Description
Terminal symbol
Description
R/L1-S/L2-T/L3
Connect to commercial power supply
U/T1-V/T2-W/T3
Connect to three-phase induction motor.
(+/P)-P1
Add on DC reactor.
(+/P)-PR
Connect to brake resistor. (Note 1, 2)
(+/P)-(-/N)
Connect to brake unit. (Note 3)
Connect enclosure of the inverter to ground. / For 440V series, special type of grounding shall be
adopted. (Note 4)
Note: 1. For SA3 series inverters, brake resistor is not included. For information related to brake resistor, please refer to
section 3.6.3 and 3.7.1.
2. For information related to regenerative voltage, please refer to 06-05(P.30) and 06-06(P.70) in section 5.7.3.
3. +/P and -/N are the positive and negative terminals of the internal DC voltage of the inverter. In order to
strengthen the braking capacity during deceleration, it is suggested to purchase the optional “brake unit” which
is mounted between the ter/P and -/N. The “brake unit” can effectively dissipate the feedback energy
from the motor to the inverter when decelerating.
4. In case there is any problem on purchasing the “brake unit,” please feel free to contact us.
