Main circuit terminal explanations
Terminal Symbol Content Explanation
R(L1),S(L2),T(L3)
AC source input terminals, to be connected to commercial power.
Ensuring the power voltage and the maximum current possible supplied
is meet the driver nameplate.
R30,S30,T30 (option)
The phase difference 30° AC source input terminals (When using
12-pulse input, a transformer with a Dual Star-delta Secondary is
necessary.)
Ensuring the power voltage and the maximum current possible supplied
is meet the driver nameplate.
R1,S1 (option)
Extra 1-phase AC source input terminals for main control card, t
o be
connected to commercial power. The voltage rating is same as
R(L1),S(L2),T(L3).These terminals can be powered both independent
and simultaneously with the main inputs. When These terminals
powered only, the drive cannot run, it can precede check signa
ls and
management parameter setting and troubleshooting only.
U(T1),V(T2),W(T3) Drive output terminals for motor connections
⊕/B1, B2
Connections for Brake Resistor (optional) . Refer to Chapter 9
⊕/B1, Θ
Connecting terminals of the external Dynamic Brake Unit.
(DC Bus, power source terminals)
P1, ⊕/B1
Connections for DC choke (option) .
Disconnect the short-circuit piece when the device is installed
Ground terminals, please have these terminals grounded following the
third-type grounding of 230V models and the special grounding of
460/575V models within the electrician regulations. There are two
ground terminals, one for AC source grounding on the input side.
The other one is for motor grounding on the output side.
