Description
R(L1)/S(L2)/T(L3)
AC power input terminal
Mains supply AC power connections.
P2(+)/N(-)
DC link terminal
DC voltage terminals.
P1(+)/P2(+) DC reactor terminal
DC reactor wiring connection. (When you
use the DC reactor, must remove short-bar)
P2(+)/B
Brake resistor terminals
Brake resistor wiring connection.
U/V/W Motor output terminals
3-phase induction motor wiring
connections.
Note
• Do not use 3 core cables to connect a remotely located motor with the inverter.
• When you operating Brake resistor, the motor may vibrate under the Flux braking operation. In
this case, please turn off the Flux braking(Pr.50).
• Make sure that the total cable length does not exceed 665ft (202m). For inverters < = 4.0kW
capacity, ensure that the total cable length does not exceed 165ft (50m).
• Long cable runs can cause reduced motor torque in low frequency applications due to voltage
drop. Long cable runs also increase a circuit’s susceptibility to stray capacitance and may trigger
over-current protection devices or result in malfunction of equipment connected to the inverter.
• Voltage drop is calculated by using the following formula:
Voltage Drop (V) = [
√
3
X cable resistance (m Ω /m) X cable length (m) X current(A)] / 1000
