5.7.3 Stall Prevention
Table 5-89: Stall Prevention Parameter Settings
* Default and Range changed by D10-01.
Parameter Display Function Range Default
L03-01 StallP Accel Sel Stall Prevention will function during acceleration.
(G+ only) 0–2 1
0 Disabled
1 General Purpose Acceleration is paused as long as the current is above
the L03-02 setting.
2 Intelligent Accelerate in the shortest possible time without
exceeding the L03-02 level.
L03-02 StallP Accel Lvl Output current level at which the Stall Prevention
during acceleration is activated. (G+ only) 0–150% *
L03-03 StallPAcc LowLim Stall Prevention lower limit during acceleration when
operating in the constant power range. Set as a
percentage of VFD rated current. (G+ only) 0–100% 50
L03-05 StallP Run Sel Control for the stall prevention during run.
(G+ only) 0–2 1
0 Disabled Runs at a set frequency. A heavy load may stall.
1 Decel Time 1 Use Decel Time 1 (B05-02)
2 Decel Time 2 Use Decel Time 2 (B05-04)
L03-06 StallP Run Level Current level to trigger Stall Prevention during run.
Depending on L03-23, the level is automatically
reduced in the constant power range (speed beyond
base speed). (G+ only)
Enabled when L03-05 is set to 1 or 2.
30–150% *
L03-11 OV Inhibit Sel Enables or disables the OV suppression function,
which allows the VFD to change the output frequency
as the load changes to prevent an OV fault. 0, 1 0
0 Disabled
1 Enabled

L03-20 DC Bus P Gain Proportional gain for Stall Prevention and overvoltage
suppression 0.00–5.00 A01-02
L03-21 Acc/Dec P Gain Proportional gain used to calculate the deceleration
rate during OV suppression function and Stall
Prevention during deceleration 0.10–10.00 sec A01-02
L03-23 CHP Stall P Sel Reduces the Stall Prevention during run level in the
constant power range. (G+ only) 0, 1 0
0 Lvl set in L3-06 Sets the Stall Prevention level that is used throughout
the entire frequency range.
1 Autom. Reduction Automatic Stall Prevention level reduction in the
constant output range. Lower limit is 40% of L03-06.
L03-24 Mtr Accel Time Time needed to accelerate the uncoupled motor at
rated torque from stop to the maximum frequency. 0.001–10.000
