SETTING DEF SETTING/RANGE
L3-05
Stall Prevention
Selection during
Run
Selects the Stall Prevention
method to use to prevent drive
faults during run. When output
frequency is 6 Hz or less, Stall
Prevention during run is disabled
regardless of the setting in L3-05.
1
1
0: Disabled – Drive runs at a set
frequency. A heavy load may cause
the drive to trip on an oC or oL fault.
1: Decel Time 1 – 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).
L3-06 Stall Prevention
Level during Run
Enabled when L3-05 is set to “1”
or “2”. 100% is equal to the drive
rated current. Decrease the set
value if stalling or excessive current
occurs within the default settings.
Upper level is determined by C6-01
and L8-38
150
150 30% to 150%
L4-01 Speed Agreement
Detection Level
These parameters configure the
multi-function output (H2-01 = 2, 4,
5) settings “Speed Agree 1”, “User
Set Speed Agree 1”, “Frequency
Detection 1”, and “Frequency
Detection 2”. Parameter L4-01
sets the level while parameter
L4-02 sets the hysteresis for the
Speed Detection Output Function.

L5-01 Number of Auto
Restart Attempts
Sets the counter for the number of
times the drive attempts to restart
when one of the following faults
occurs: oC, ov, PF, rH, rr, oL1, oL2,
oL3, Uv1. When the drive operates
without fault for 10 minutes, the
counter will be reset.

L6-01 Torque Detection
Selection 1
Selects the overtorque operation.
Overtorque is determined by the
settings in parameters L6-02 and
L6-03. The multi-function output
settings (H2-01 = B and 17) are
also active if programmed.

0: Disabled
1: oL1 at Speed Agree – Alarm
2: oL3 at RUN – Alarm
3: oL3 at Speed Agree – Fault
4: oL3 at RUN – Fault
L6-02 Torque Detection
Level 1
Sets the overtorque detection level.
100% is equal to the motor rated
current.

L6-03 Torque Detection
Time 1
Sets the length of time an
overtorque condition must exist
before Torque Detection is
triggered.

Internal Dynamic
Braking Resistor
Protection
Selection (ERF
type)
Selects the Braking resistor when
using a 3% duty cycle heatsink
mounted braking resistor. This
parameter does not enable or disable
the braking transistor of the drive.
0
0
0: Resistor overheat protection
disabled
1: Resistor overheat protection
enabled.
