For the
030G/037P and
lower models
For the 037G/045P and
higher models
R, S, T
Power input of the main circuit
3-phase AC input terminals which are
generally connected with the power
supply.
U, V, W
The
3-phase AC output terminals which are
generally connected with the motor.
P1
This terminal is
inexistent
DC reactor terminal 1
P1 and (+) are connected with the
terminals of DC reactor.
(+) and (-) are connected with the
terminals of braking unit.
PB and (+) are connected with the
terminals of braking resistor.
(+)
Braking resistor
1
DC reactor terminal 2,
braking unit terminal 1
(-)
/
Braking unit terminal 2
PB
Braking resistor
terminal 2
This terminal is
inexistent.
PE
380V: the grounding resistor is less than
10 ohms
Protective grounding terminals, every
machine is provided 2 PE terminals as the
standard configuration. These terminals
should be grounded with proper
techniques.
A1 and A2
Control power terminal
Optional for the 018G/022P and higher
models ( connect to external 220V control
power). Power can be supplied via
auxiliary power, making it more
convenient for commissioning.
