All Modes
Sets the time before iov (overvoltage at the power supply side) is detected,
in 0.01 s units.
If the state in which the output voltage exceeds the value set for L2-41
continues for the time set for L2-42 or longer, iov (overvoltage at the
power supply side) is detected.
L3: Stall Prevention
V/f OLV
0: Disabled. Drive runs at a set frequency. A heavy load may cause speed
loss.
1: General purpose. Acceleration is paused as long as the current is above
the L3-02 setting.
2: Intelligent. Accelerate in the shortest possible time without exceeding
the L3-02 level.
V/f
OLV
Used when L3-01 = 1 or 2. 100% is equal to the drive rated current.
V/f OLV
Sets Stall Prevention lower limit during acceleration when operating in the
constant power range. Set as a percentage of the drive's rated current.
All Modes
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.
V/f OLV
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.
V/f OLV
Enabled when L3-05 is set to 1 or 2. 100% is equal to the drive rated
current.
V/f
OLV
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
V/f OLV
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.
V/f OLV
Sets the time the current must exceed the Stall Prevention level to activate
Stall Prevention.
L4: Speed Detection
All Modes
L4-01 sets the frequency detection level for contact output functions H2-
= 2, 3, 4, 5.
L4-02 sets the hysteresis or allowable margin for speed detection.
