* In Flux Vector or in Open Loop Vector 2, the setting range becomes 0 to 2.
* *1 Values shown here are for 208-240V drives. Double the value when working with 380-480V drives.
L3-05
Stall
Prevention
Selection
During
Running
Selects the stall prevention
method to use to prevent Drive
faults during run.
0: Disabled - Drive runs a set
frequency. A heavy load
may cause the Drive to trip
on an OC or OL fault.
1: Decel Time 1 - In order to
avoid stalling during heavy
loading, the Drive will
decelerate at Decel time 1
(C1-02) if the output current
exceeds the level set by
L3-06. Once the current
level drops below the L3-06
level, the Drive will
accelerate back to its
frequency reference at the
active acceleration rate.
2: Decel Time 2 - Same as
setting 1 except the Drive
decelerates at Decel Time 2
(C1-04).
When output frequency is 6Hz
or less, stall prevention during
run is disabled regardless of
the setting in L3-05.

This parameter is enabled when
L3-05 is set to "1" or "2". Drive
rated current is set as 100%.
Decrease the set value if

Selection
Enables or disables OV
suppression function, which
allows the Drive to change the

changes, to prevent an OV
fault.

Sets the DC bus voltage level at

function is active.
Normally, this setting does not
require adjustment. Decrease

even when OV suppression is
enabled.
