L3-02
(490H)
Stall Prevention
Level during
Acceleration
Used when L3-01 = 1 or 2. 100% is equal to the drive rated current.
Default: 120%
Min: 0%
Max: 150%
207
L3-03
(491H)
Stall Prevention
Limit during
Acceleration
Sets Stall Prevention lower limit during acceleration when operating in the
constant power range. Set as a percentage of the drive rated current.
Default: 50%
Min: 0%
Max: 100%
207
L3-04
(492H)
Stall Prevention
Selection during
Deceleration
0: Disabled. Deceleration at the active deceleration rate. An OV fault may
occur.
1: General purpose. Deceleration is paused when the DC bus voltage
exceeds the Stall Prevention level.
Default: 1
Min: 0
Max: 1
207
L3-05
(493H)
Stall Prevention
Selection during
Run
0: Disabled. Drive runs at a set frequency. A heavy load may cause speed
loss.
1: Decel time 1. Uses the deceleration time set to C1-02 while Stall
Prevention is performed.
2: Decel time 2. Uses the deceleration time set to C1-04 while Stall
Prevention is performed.
Default: 1
Min: 0
Max: 2
208
L3-06
(494H)
Stall Prevention
Level during Run
Enabled when L3-05 is set to 1 or 2. 100% is equal to the drive rated current.
Default: 120%
Min: 30%
Max: 150%
208
L3-11
(4C7H)
Overvoltage
Suppression
Function Selection
Enables or disables the OV suppression function, which allows the drive to
change the output frequency as the load changes to prevent an OV fault.
0: Disabled
1: Enabled
Default: 0
Min: 0
Max: 1
209
L3-23
(4FDH)
Automatic
Reduction Selection
for Stall Prevention
during Run
0: Sets the Stall Prevention level set in L3-06 that is used throughout the
entire frequency range.
1: Automatic Stall Prevention level reduction in the constant output range.
The lower limit value is 40% of L3-06.
Default: 0
Min: 0
Max: 1
208
L3-27
(456H)
Stall Prevention
Detection Time
Sets the time the current must exceed the Stall Prevention level to activate
Stall Prevention.
Default: 50 ms
Min: 0 ms
Max: 5000 ms
209
L4: Speed Detection
L4-01
(499H)
Speed Agreement
Detection Level
Sets the frequency detection level for contact output functions H2-
= 2,
3, 4
, 5.
Default: 0.0
Min: 0.0 Hz
Max: 120.0 Hz
<20>
210
L4-02
(49AH)
Speed Agreement
Detection Width
Sets the hysteresis or allowable margin for speed detection.
Default: <10>
Min: 0.0 Hz
Max: 20.0 Hz
210
L4-03
(49BH)
Speed Agreement
Detection Level
(+/-)
Sets the frequency detection level for contact output functions H2- = 13,
14, 15, 16.
Default: 0.0
Min: -120.0 Hz
Max: 120.0 Hz
<20>
210
L4-04
(49CH)
Speed Agreement
Detection Width
(+/-)
Sets the hysteresis or allowable margin for speed detection.
Default:
<10>
Min: 0.0 Hz
Max: 20.0 Hz
210
L4-05
(49DH)
Frequency
Reference Loss
Detection Selection
0: Stop. Drive stops when the frequency reference is lost.
1: Run. Drive runs at a reduced speed when the frequency reference is lost.
If the frequency reference decreases to 10% of the frequency reference of
0.4 s before, the drive runs at “frequency reference of 0.4 s before × value
set in L4-06”.
Note: This parameter is valid only when Frequency Reference
Selection 1 is set to analog input terminals (b1-01 = 1).
Default: 0
Min: 0
Max: 1
210
No.
