Description
V/f CL-V/f OLV CLV AOLV
Sets the method of the Stall Prevention During Acceleration.
1 : Disabled
2 : General Purpose
3 : Intelligent Accel
4 : ILim Mode
V/f CL-V/f OLV CLV AOLV
Sets the output current level to start Stall Prevention during acceleration as a percentage
of the drive rated output current.
V/f CL-V/f OLV CLV AOLV
Sets the lower limit for the stall prevention level during acceleration used for constant
output ranges as a percentage of the drive rated output current.
V/f CL-V/f OLV CLV AOLV
Enables Stall Prevention during deceleration.
0 : Disabled
1 : Enabled
V/f CL-V/f OLV CLV AOLV
Sets the method that the drive will use to prevent overvoltage faults when decelerating.
Note:
1. To connect a dynamic braking option (braking resistor or braking resistor unit)
to the drive, set this parameter to 0 or 3. Parameter values 1, 2, 4, and 5 will
enable Stall Prevention function during deceleration, and the dynamic braking
option will not function.
2. The setting range changes when the A1-02 [Control Method] value changes:
• When A1-02 = 5 [PM OLVector], setting range is 0 to 2
• When A1-02 = 6, 7, or 8 [PM AOLVector, PM CLVector, or EZ Vector],
setting range is 0, 1.
0 : General Purpose
1 : Automatic Decel Reduction
2 : Gen Purpose w/ DB Resistor
3 : HiFlux Overexcitation
4 : HiFlux2 Overexcitation
V/f CL-V/f OLV CLV AOLV
Sets the function to enable and disable Stall Prevention During Run.
Note:
An output frequency less than 6 Hz will disable Stall Prevention during Run
regardless of L3-05 and L3-06 [StallP Level@Run] settings.
0 : Dec Time 1 (C1-02)
1 : Dec Time 2 (C1-04)
V/f CL-V/f OLV CLV AOLV
Enables Stall Prevention during Run.
0 : Disabled
1 : Enabled
V/f CL-V/f OLV CLV AOLV
Sets the current level that starts Stall Prevention during run. A setting of 100% is equal
to the drive rated current.
Note:
This parameter is applicable if L3-05 = 1 [StallP@RUN Enable = Enabled] and
L3-51 = 0, 1 [StallP@RUNDecTime= Dec Time 1 (C1-02), Dec Time 2 (C1-04)].
V/f CL-V/f OLV CLV AOLV
Sets the overvoltage suppression function.
0 : Disabled
1 : Enabled
V/f CL-V/f OLV CLV AOLV
Sets the target value for the DC bus voltage when the overvoltage suppression function
and the Decel Stall Prevention function (Intelligent Stall Prevention) are active.
V/f CL-V/f OLV CLV AOLV
Sets the proportional gain used to control the DC bus voltage.
V/f CL-V/f OLV CLV AOLV
Sets the proportional gain to calculate acceleration and deceleration rates.
V/f CL-V/f OLV CLV AOLV
Sets the momentary deceleration time that the drive will use when it tries to accelerate a
PM motor and detected motor stalls. This function is applicable when L3-01 = 2 [StallP
Mode@Accel = General Purpose].
