StallP Accel Sel
0: Disabled (Motor accelerates at active acceleration, C1-01 or C1-03.
The motor may stall if load is too heavy or accel time is too short.)
1: General Purpose (When output current exceeds L3-02 level,
acceleration stops. It starts to accelerate at current value recovery.)
2: Intelligent (The active acceleration rate, C1-01 or C1-02, is ignored.
Acceleration is completed in the shortest amount of time w/o
exceeding the current value set in L3-02.

StallP Decel Sel
0: Disabled (The drive decelerates at the active deceleration rate,
C1-02 or C1-04. If the load is too large or the deceleration time is too
short, an OV fault may occur.)
1: General Purpose (The drive decelerates at the active deceleration
rate, C1-02 or C1-04, but if the main circuit DC bus voltage reaches the
stall prevention level the output frequency will clamp. Deceleration
will continue once the DC bus level drops below the stall prevention
level.)
2: Intelligent (The active deceleration rate is ignored and the drive
decelerates as fast as possible w/o hitting OV fault level.)

During Decel
StallP Run Sel
0: Disabled (drive runs a set frequency.) A heavy load may cause the
drive to trip on an OC fault.
1: Decel Time 1 (In order to avoid stalling during heavy loading, the
drive will start to decelerate at Decel time 1 (C1-02) if the output
current exceeds the level set by L3-06. Once the current level drops
below the L3-06 level the drive will accelerate back to its set frequency
at the active acceleration rate.)
2: Decel Time 2 (Same as setting 1 except the drive decelerates at
Decel Time 2 (C1-04).) For 6 Hz or less frequency, stall prevention
function during run is disabled regardless of L3-05 set.

StallP Run Level
This function is enabled when L3-05 is “1” or “2”.
Drive rated current is set as 100 %.
Normally, changing the setting is not required.
Decrease the set value if stalling occurs at factory setting.

Determines how the drive will react when the frequency reference is
lost.
0: Stop (Disabled) - Drive will not run at the frequency reference.

Max Restart Time
If the restart fails (or is not attempted due to a continuing fault
condition, e.g. an OV fault) the drive waits the Maximum Restart Time
