Terminal Function Setting and Instruction
R、S、T
VFD
：
Three phase 220V/380V
Model connect with R
、S、T
terminals
Single phase 220V Model
connect with R、T terminals
Air switch should be used as the
over-current protection device in front of the
VFD power. If there is LCDI, and it is afraid
of breakdown, please choose the LCDI
whose sensitivity level is above 200mA and
reaction period last more than 100ms.
U、V、W
VFD output, connected
with electrical machine
In order to reduce the leakage of current, the
connection wire should not be over 50
meters.
P+、PB
Connected with braking resistor
According to the list of braking resistors,
choose an appropriate one.
PE
Connected with the ground
The VFD should be connected with the
