KEB ZeroSpeed
Operation
Sets the operation when the output frequency decreases below the zero level (DC
braking injection starting frequency) during KEB deceleration when L2-01 = 1
[RideThru@PwrLoss = Enabled] and L2-50 = 2 to 4 [RidThruMode@PwrLoss = KEB
ModeKEB Stop Mode, or KEB Decel to Stop].

StallP Level@Accel
Sets the output current level at which the Stall Prevention function operates during
acceleration where the drive rated output current is 100%.
Note:
The upper limit to the setting range changes when the setting for C6-01 [ND/HD
Duty Selection] changes.
• 150% when C6-01 = 0 [HD Rating]
• 120% when C6-01 = 1 [ND Rating]

StallP@Decel Mode
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, or 8 [PM AOLVector, or EZ Vector], setting range is 0, 1.

StallP@RUN Enable
Enables Stall Prevention during Run.
Note:
• An output frequency less than 6 Hz disables Stall Prevention during Run. The
setting values of L3-05 and L3-06 [StallP Level@Run] do not have an effect.
• The setting range changes when the A1-02 [Control Method] value changes:
–A1-02 = 0, 5 [V/f Control, PM OLVector] : 0 to 2
–A1-02 = 8 [EZ Vector] : 0, 3

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.
