Quick Guide
E.oL2
Inverter
over-load
●
Load is too heavy.
●
Acceleration time is too
short.
●
Start motor when running.
●
V/F curve setting is not sui-
table. Or torque boost too
high.
●
Select inverter with right capaci-
tance.
●
Prolong acceleration time
●
Restart motor until it totally
stops. Set [F1.00] as 1or2.
●
Reset V/F curve or torque boost
value.
E. SC
System
abnormal
●
Acceleration time is too
short.
●
Short circuit between inver-
ter output phases or earth.
●
Module is damaged.
●
Electromagnetic disturb.
●
Prolong acceleration time pro-
perly.
●
Check peripheral equipments
and restart after fault eliminating.
●
Seek support from vendor.
●
Check system wiring, earth,
shield and deal as required.
E.oH1
Inverter
over-heat
●
Temperature is too high.
●
Air channel is blocked.
●
Fan connection parts loose.
●
Fan is damaged.
●
Temperature detection
circuit fault
●
Meet the environment require-
ment.
●
Clear the air channel.
●
Check and reconnect the wire
●
Change the same new fan.
●
Seek support from vendor.
E.oH2
Rectifier
over-heat
●
Temperature is too high.
●
Air channel is blocked.
●
Fan connection parts loose.
●
Fan is damaged.
●
Temperature detection
circuit fault
●
Meet the environment require-
ment.
●
Clear the air channel.
●
Check and reconnect the wire.
●
Change the same new fan.
●
Seek support from vendor.
E.Fb1
PID feed-
back over
upper limit
●
PID feedback wire breaks.
●
PID feedback channels
parameter is wrong.
●
Analog feedback channel is
abnormal.
●
Check PID feedback wire.
●
Check the PID feedback channel
parameter setting.
●
Seek support from vendor.
E.Fb2
PID feed-
back over
lower limit
●
PID feedback wire breaks.
●
PID feedback channels
parameter is wrong.
●
Analog feedback channel is
abnormal.
●
Check PID feedback signal wire.
●
Check the PID feedback channel
parameter setting.
●
Seek support from vendor.
E.TE1
Motor
static
detection
fault
●
Detection overtime
●
Start static detection when
motor is running.
●
Capacitance difference is
too big between motor and
inverter.
●
Motor parameter setting
mistake.
●
Check motor connection wire.
●
Detect after motor stops totally.
●
Change inverter model.
●
Reset parameter according to
nameplate.
