Overvoltage in
stopping
Not enough voltage tested when AC drive stops.
Select test in environment of radiator tempera-
ture≥OH1 test standard, AC drive continue
running.
When the output current of AC drive is>C24
(over rotation moment of force test standard),
select over rotation moment of force, AC drive
continue running.
External BB order input from control circuit
terminal.
It is OFF when right/opposite running order
input over 500ms.
In circumstance of A03(operation mode sellec-
tion)
≥

from RS485 when power is on.
AC drive overheat alarm signal is input from
control circuit terminal.
Sellect continue running when RS485
