Stall Prevention
Selection during
Acceleration
Selects the Stall Prevention method used to prevent excessive current
during acceleration.
0:
Disabled - Motor accelerates at active acceleration rate. The motor
may stall if load is too heavy or accel time is too short.
1: General Purpose - When output current exceeds L3-02 level,
acceleration stops. Acceleration will continue when the output
current level falls below the L3-02 level.

Stall Prevention
Selection during
Deceleration
When using a braking resistor, use setting "0".
0: Disabled - The drive decelerates at the active deceleration rate. If
the load is too large or the deceleration time is too short, an ov fault
may occur.
1:
General Purpose - The drive decelerates at the active deceleration
rate, but if the main circuit DC bus voltage reaches the Stall
Prevention level, deceleration will stop. Deceleration will continue
once the DC bus level drops below the Stall Prevention level.
4: Overexcitation Deceleration - Decelerates with the flux level
determined by n3-13 (Overexcitation Gain).

Stall Prevention
Selection during
Run
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 - 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 6 Hz or less, Stall Prevention during run
is disabled regardless of the setting in L3-05.

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 with the
default settings.
Upper level is determined by C6-01 and L8-38.

L4: Frequency Detection
Use L4 parameters to configure frequency detection operation.

L5: Fault Reset
Use L5 parameters to configure Automatic Restart after fault.

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, oL1, oL2,
oL3, Uv1.
When the drive operates without fault for 10 minutes, the counter will
be reset.

L6: Overtorque Detection
Use L6 parameters to configure overtorque detection.
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: oL3 at Speed Agree - Alarm (overtorque detection only active
during Speed Agree and operation continues after detection).
2: oL3 at RUN - Alarm (overtorque detection is always active and
operation continues after detection).
3: oL3 at Speed Agree - Fault (overtorque detection only active during
Speed Agree and drive output will shut down on an oL3 fault).
4: oL3 at RUN - Fault (overtorque detection is always active and drive
output will shut down on an oL3 fault).
