Overload Prevention Control
Enables or disables the overload suppressing control. If enabled, this function code
is used to set the deceleration (Hz/s).
Before the inverter enters Alarm mode due to the heat sink overheat or overload
(alarm code:
OH1
or
OLU
), this control decreases the output frequency of the in-
verter to suppress the trip.
Apply this control to equipment (such as pumps) whose drive frequency drops in
line with any decrease in load. If you want to proceed to drive such kind of equip-
ment even the inverter slows down the output frequency, enable this control.
Do not use this control to equipment whose load does not slow if the
inverter output frequency drops, as it will have no effect.
If the following functions to limit the output current are enabled (F43
z
0
and H12 = 1), this control does not work.

Priority on STOP Key/Start Check
The inverter can be operated using a functional combination of "Priority on STOP
Key" and "Start Check."
„
STOP key priority
Pressing the key on the keypad forces the inverter to decelerate and stop the
motor even if the inverter is running by any run commands given via the terminals or
communications (link operation). After the motor stops, the inverter issues alarm
"E 6."
„
Start check function
The inverter prohibits any run commands to be executed and displays " E 6 " on the
LED of keypad when:
- The power is first applied.
- The key is pressed or the (RST) signal is turned on to cancel the alarm.
- Link command (LE) has switched inverter operations.
