 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.
P1-(+/P)
Connect to DC reactor.
(+/P)-PR
Connect to brake resistor
(+/P)-(-/N)
Connect to brake unit or input DC voltage(AB frame without N terminal)
Note: 1. For SE3 series inverters, brake resistor is not included. For information related to braking resistor, please refer
to Section 3.6.3 and 3.7.1.
2. For information related to regenerative voltage, please refer to 06-05 and 06-06 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 terminals +/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 “brake unit,” please feel free to contact us.
