function 40 becomes on, indicating that the running time this time is reached. It is effective only for
drive running this time. The previous running time is not added.
5.11.15 Output Power correction
Function Code
Parameter Name
Default
F8-54
Output power correction coefficient
Setting Range
100.0%
0.00% to 200.0%
This function parameter sets output power correction coefficient. When output power (U0-05)
is not equal to expected value, perform linear correction via this parameter.
5.11.16 Deceleration Time for Emergency Stop
Function Code
Parameter Name
Default
F8-55
Deceleration time for emergency
stop
Setting Range
100.0%
0.00% to 200.0%
When the system is in emergency status, the AC drive decelerates based on the setting of F8-55
(deceleration time for emergency stop). If F8-55 = 0 in V/F control, the AC drive decelerates based
on the setting of F0-19 (Acceleration/Deceleration time unit).
6: Regular inspection and maintenance
Before doing the periodic inspection, first stop operation, shut off power supply and take
away the cover.
Even when the power supply of the AC drive is shut off, there’s still charged voltage on the
filter capacitors and it takes some time to discharge.
In order to avoid the danger, be sure to wait until the charge indicator goes
out and test with a voltmeter to ensure the voltage is lower than safe value
(≤25Vdc) before the operation of inspection.
6.2 Periodic Inspection
Notice!
1.For AC drives ≤22kW, wait 5 minutes after shutting down the power, and wait 10 minutes
for those ≥ 30kW. Not until the DC voltage between terminals N- and P+ is lower than DC25V
could examination operation with cover removed begin.
2.No one other than the appointed operators could perform maintenance and part replacement
and other operations.(Metal objects such as watches and rings should be taken off before operat
-
ion, and use tools with insulation in operation.)
3.Rebuilding the AC drive is absolutely forbidden.
4.Avoid electric shock and facility accident.

inspection
During power-up and operation, without taking away the cover, check the operation of AC
drive with eye survey from outside and confirm that there’s nothing abnormal. Usually, check
the followings:
■
whether the operation performance accord with the regulation
■
whether the environment accord with the regulation
■
whether keyboard panel display is normal
■
whether without abnormal noises, vibrations and abnormal odor
■
whether without abnormality such as overheat or change in color
