Alarm Outputs for Maintenance Monitors
You can use
H2-xx [MFDO Function Select]
to send a message that tells you when a specified component is near
the end of its performance life estimate. Set the applicable value to
H2-xx
as shown in
for your
component.
When the specified component is near the end of its performance life estimate, the MFDO terminals set for
H2-xx
= 63 [Maintenance]
will activate, and the keypad will show an alarm that identifies the component to replace.

LT-1
Cooling Fan
Maintenance Time
The cooling fan is at 90% of its expected
performance life.
Replace the cooling fan, then set
o4-03 = 0 [Fan.Oper
Setting = 0 h]
to reset the cooling fan operation time.
63
LT-2
Capacitor
Maintenance Time
The capacitors for the main circuit and
control circuit are at 90% of expected
performance life.
Replace the board or the drive.
Contact the manufacturer or your nearest sales
representative to replace the board.
LT-3
SoftChargeBypassRe
lay MainteTime
The soft charge bypass relay is at 90% of its
performance life estimate.
Replace the board or the drive.
Contact the manufacturer or your nearest sales
representative to replace the board.
LT-4
IGBT Maintenance
Time (50%)
The IGBT is at 50% of its expected
performance life.
Check the load, carrier frequency, and output frequency.
TrPC
IGBT Maintenance
Time (90%)
The IGBT is at 90% of its expected
performance life.
Replace the IGBT or the drive.

Related Parameters
Replace the component, then set Maintenance Setting
o4-03, o4-05, o4-07, and o4-09 = 0
to reset the
Maintenance Monitor. If these parameters are not reset after the corresponding parts have been replaced, the
Maintenance Monitor function will continue to count down the performance life from the value that was reached
with the old part. If the Maintenance Monitor is not reset, the drive will not have the correct value of the
performance life for the new component.
Note:
The maintenance period changes for different operating environments.

o4-03
Fan.Oper Setting
Sets the value from which to start the cumulative drive cooling fan operation time in 10-hour units.
Note:
When
o4-03 = 30
has been set, the drive will count the operation time for the cooling fan from 300 hours
and
U4-03 [Fan Oper.Time]
will show
300 h
.
o4-05
Cap.Maint.Setting
Sets the value from which to start the count for the main circuit capacitor maintenance period as a percentage.
o4-07
PreChgRly Preset Maintenance Cnt
Sets as a percentage the value from which to start the count for the soft charge bypass relay maintenance
time.
o4-09
IGBT Preset Maintenance Cnt
Sets the value from which to start the count for the IGBT maintenance period as a percentage.
