Specification of high-performance vector convertor
d)
Connection terminal P1, (+) of external DC reactor
For the frequency convertor at above 220V37KW and 380V75kW, connection strap between P1
and (+) terminals needs to be removed when installing DC reactor externally, and connect DC
reactor between two terminals.
e)
U, V, W on output side of frequency convertor: output side of frequency convertor shall not
connect capacitor or surge absorber, otherwise it will lead to frequent protection and even damage
of convertor. Due to influence of distributed capacitance, if motor cable is too long, electric
resonance will produce easily, which will damage motor insulation or produce large leak current
and frequent protection of convertor. If motor cable is >100m, AC input reactor should be installed.
f)
Earthing terminal PE\
For different models, the marking of earthing terminal may be different, but the meaning is same. In
above descriptions,
Keep reliable earthing of earthing terminal and resistance value of ground wire should be <0.1Ω,
otherwise it will lead to abnormal operation and even damage of device. Do not use earthing terminal
PE or
and N terminal on null line of power in common.
3.2.5 Control terminal and wiring
1) Layout diagram of terminals on control circuit is as below:
(Note: there's no short-circuit strap between CME and COM, OP and +24V of frequency
convertor. Users select wiring way of CME and OP respectively through J10, J9）
