In case the inverter trip occurs, the inverter restarts by
‘The number of automatic restart’
at FUN_60. In case of
the inverter trip, the inverter resets the fault automatically and waits for ‘
Delay time before automatic
restart’
at
FUN_61 and restarts. The inverter will not restart any more, blocks the IGBT gating signals and issues the trip message
if the inverter trip occurs more than
‘The number of automatic restart’
at FUN_60.
CAUTION
l
Particular attention should be directed to this function as the inverter clears the fault automatically
and motor suddenly restarts when trip occurs.
l
Auto restart function is disabled when the following trips occur.
①
BX (Emergency stop)
②
Low Voltage
③
Arm Short-U (V, W, DB)
④
Fuse Open
⑤
Ext Trip-B (External trip B)
⑥
InvOver Heat (inverter overheated)
⑦
MotOver Heat (Motor overheated)
⑧
Encoder Err (Encoder error)
⑨
Over Load (Overload trip)
⑩
E-Thermal (Electronic thermal protection)
l
If trip does not occur for 30 sec after restart, inverter adds the number of restart by one
automatically and this cannot exceed setting value.
6.4.11 Wait time for restart upon stop
l
Only active when FUN_03 is set to ‘Free-run’ and operating method is ‘Terminal’.
