motor temperature is greater than motor overheating alarm threshold (F07.05), the
numeric output terminal “25: Motor Overload Pre-alarming” is enabled and this signal is
used for instruction; if motor temperature is greater than motor overheating protection
threshold (F07.04), inverter will give an alarm about motor overheating fault (E12) and
start corresponding protection action.
★ Motor overheating fault (E12) can not be reset immediately until motor temperature
drops to a value far below the protection threshold.
No.

F07.06=0: Disabled
Overvoltage stall disabled; it’s not recommended to set F07.06 as 0, if there is no
external braking unit.
Undervoltage stall disabled;
F07.06=1: Undervoltage Stall, Enabled
When bus voltage is lower than the value set through F07.08, inverter stops after
decelerating to zero, and gives an alarm for stable undervoltage fault (SIU).
F07.06=2: Overvoltage Stall, Enabled
f overvoltage stall is enabled, the stall voltage is set by F07.07.
DC bus overvoltage is generally caused by deceleration, because at the time of
