Summary of Function Settings
Settings Functions Descriptions
0
No function MO has no function.
01
AC drive in operation The drive is ON when it receives voltage or operation command.
2
Zero speed frequency signal
(including STOP)
Zero speed output signals (including STOP).
3
AC drive ready
Active when the drive is ON and no abnormality detected or
abnormality is cleared.
4
Low voltage warning(Lv) Active when the detected input voltage is too low.
5
Fault indication Active when fault occurs.
6
Overhead warning (Pr.06.09)
A
ctive when IGBT or heat sink overheats to prevent OH turn off
the drive. When temperature higher than 85 = ON, lower than
<80 = OFF .
7
Detection of braking resistor
action level
Active when drive begins software braking, this signal can be
used as brake module VFDB action signal or indicator.
8
Warning indication Active when warning is detected.
9
Over voltage warning Active when over-voltage is detected.
