This function provides a tentative information for service life of the parts. If this
signal is issued, check the service life of these parts in your system according to
the maintenance procedure to determine whether the parts should be replaced or
not. To maintain stable and reliable operation and avoid unexpected failures, daily
and periodic maintenance must be performed.
For details, refer to Chapter 7, Section 7.2, Table 7.2 " Replacement Parts
Judgement with Menu #5 "Maintenance Information" as a Guide."
Inverter running--(RUN2)
(Function code data = 35)
This signal is turned on when the motor is driven by the frequency higher than the
starting frequency or the DC braking is activated.
Overload prevention control--(OLP)
(Function code data = 36)
This signal is turned on when the overload prevention function is activated if the
frequency drop rate comes to be the setting specified by function code H70. The
minimum ON-duration is 100 ms.
For details of the overload prevention control, refer to the descriptions of
function code H70.
Current detection--(ID)
(Function code data = 37)
This signal is turned on when the output current exceeds the operation level
specified by function code E34 and stays in this status for the duration specified
by function code E35 (on delay timer). The minimum ON-duration is 100 ms.
Function codes E34 and E35 are effective not only for the current detec-
tion (ID), but also for the operation level of the overload early warning
(OL) and low-level current detection (IDL), and the setting of the timer
count.
Low level current detection--(IDL)
(Function code data = 41)
This signal is turned on when the output current drops below the operation level
specified by function code E34 and stays in this status for the duration specified
by function code E35 (on delay timer). The minimum turning-ON time is 100 ms.
Function codes E34 and E35 are effective not only for the low-level
current detection (IDL), but also for the operation level of the overload
early warning (OL) and current detection (ID), and the setting of the timer
count.
Alarm relay contact output (for any fault)--(ALM)
(Function code data = 99)
This signal is turned on if the protection function is activated so that the inverter
enters Alarm mode.
