Equipment
service life
(number of
startups)
(1) Equipment service
life (number of start-
ups)
-
Displayed when the motor number of
startups reaches the number set in 1st
Preset Startup Count for Motor Mainte-
nance (3008Hex-50Hex).
Additionally, the current number of start-
ups can be confirmed in 1st Startup
Count for Motor (3008Hex-2DHex),
therefore before reset, set
3008Hex-2DHex data to 0000.

Life prediction (1) Life prediction -
Any one of the main circuit capacitor
used in the inverter, the electrolytic ca-
pacitor inside the inverter
, and the cool-
ing fan has reached the end of its life.
Referring to 8-8-10 Capacitor Life Warn-
ing Signal (WAC) on page 8-85,
8-8-13 Cooling Fan Life Warning Signal
(WAF) on page 8-88 and 8-8-14 Life
Alarm (LIFE) on page 8-88, check the
status of consumable parts.

Cooling fin
overheat pre-
diction
(1) Cooling fin over-
heat prediction
-
Displayed as a prediction before the
cooling fine overheat (alarm code: 11) oc-
curs. For measures, refer to cooling fine
overheat (alarm code: 1
1) ( page 9-17).
65 Hex

0000 Hex
Motor over-
load prediction
(1) Motor overload
prediction
-
Displayed as a prediction prior to a motor
overload alarm (alarm code: 17, 18) oc-
curring, and sets the current value at
which the Overload early warning 2 Level
(OL2) (3005Hex-23Hex) operates.
Check that the actual current flowing in
the motor is not higher than the value set
in 3005Hex-23Hex.
69 Hex

0000 Hex
PID warning
output
(1) PID warning out-
put
-
Displayed when a warning (warning from
absolute value, warning from PID error)
is output during PID operation. For de-
tails, refer to Excessive PID deviation
(OD) on page 8-1
18.
68 Hex
(rEF)
0000 Hex
Command
loss
(1) Command loss -
When the analog frequency settings (ter-
minal AI1) command suddenly decreases
to 10% or less, it is judged to be a wire
break and a reference loss alarm (alarm
code: 68) is displayed. Check the wiring.
