(603FH)
E12
Lvd
DC bus voltage
is lower than the
setting in
Pr02-07 during
deceleration.
(Lvd)
4. Lvn often occurs when the motor
drive has a power failure while the
operating signals are still being sent.
000CH 2 3220H
E13
Lvn
DC bus voltage
is lower than the
setting at
Pr02-07 when
running at
constant speed
(Lvn)
000DH 2 3220H
E14
LvS
DC bus voltage
is lower than the
setting at
Pr02-07 at stop
(LvS)
000EH 2 3220H
E15
orP
Phase loss
protection (orP)
Check if only single phase power is sent
or phase los occurs for three phase
models
000FH 2 3130H
E16
oH1
IGBT’s
temperature
exceeds the
protection level
(oH1)
1. Check if ambient temperature is too
high.
2. Check if there is any foreign object on
the heat sink and if the fan is running.
3. Check if there is sufficient space for air
circulation for Hybrid Servo Drive
0010H 3 4310H
E17
oH2
Capacitors’
temperature
exceeds the
protection level )
(oH2)
1.Check if ambient temperature is too
high.
2.Check if there is any foreign object on
the heat sink and if the fan is running.
3.Check if there is sufficient space for air
circulation for hybrid servo drive
0012H 3 FF00H
E18
tH1o
Hardware failure
(tH1o)
Send back to manufacturer for repair.
0012H 8 FF00H
E19
tH2o
Hardware failure
(tH2o)
Send back to manufacturer for repair.
0012H 8 FF01H
E20
IGBT overheated
and cooling fan
failure. (oHF)
Check the fan kit to see if it is blocked.
Return to factory for repair.
