Description
V/f CL-V/f OLV CLV AOLV
Sets the current level to trigger Stall Prevention during run. A
setting of 100% is equal to the drive rated current.
Note:
• This parameter is valid if L3-05 = 1, 2 [Stall Prevent Select
during Run = Decel time 1, Decel time 2].
• The upper limit and default for this setting is determined by C6-
01 [Normal / Heavy Duty Selection] and L8-38 [Carrier
Frequency Reduction].
V/f CL-V/f OLV CLV AOLV
Enables or disables the overvoltage suppression function.
0 : Disabled
1 : Enabled
V/f CL-V/f OLV CLV AOLV
Set the target value for the DC bus voltage used when the
overvoltage suppression function and the Decel Stall Prevention
function (Intelligent Stall Prevention) are running.
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 used to calculate acceleration and
deceleration rates.
V/f CL-V/f OLV CLV AOLV
Sets the brief deceleration time used when stalling occurs while
accelerating a PM motor. This function is valid when L3-01 = 1
[Stall Prevent Select duringAccel = General Purpose].
V/f CL-V/f OLV CLV AOLV
Selects whether to automatically diminish the Stall Prevent Level
during Run for constant output ranges.
0 : Level set in L3-06
1 : Automatic Reduction
V/f CL-V/f OLV CLV AOLV
Sets the motor acceleration time taken to reach the maximum
frequency at the motor rated torque for single drive motors that are
stopped.
V/f CL-V/f OLV CLV AOLV
Sets the ratio between motor inertia and machine inertia.
V/f CL-V/f OLV CLV AOLV
Sets the capacity for external main circuit capacitors. Normally
there is no need to change this setting. Set this parameter when
using the KEB Ride-Thru function.
V/f CL-V/f OLV CLV AOLV
Sets a delay time from when the Stall Prevention level is reached
and the actual Stall Prevention function is activated.
V/f CL-V/f OLV CLV AOLV
Sets the filter time constant in units of seconds used to return the
torque limit to its original value while the KEB operation is
executing under Single Drive KEB Ride-Thru mode.
V/f CL-V/f OLV CLV AOLV
Sets the width for speed agreement when L3-04 = 2 [Decel Stall
Prevention Selection = Automatic Decel Reduction]. Normally there
is no need to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets the gain used to suppress current or motor speed hunting during
operation when L3-01 = 3 [Stall Prevent Select during Accel = ILim
Mode]. Normally there is no need to change this setting.
