1. Available in Open-Loop V/F Control, Closed-Loop V/F Control and PM Open-Loop Vector Control control
methods.
2. Disable when the output frequency is below 6 Hz regardless the P3-05 and P3-06 settings.
0 : Disabled
The drive runs at the set frequency command. A heavy load might cause the motor too stall
and triggered an oC (Overcurrent) or oL1 (Motor Overload) to stop the motor.
1 : Enabled (Deceleration Time 1)
When the drive output current exceeds the P3-06 (Stall Prevention Level during Run) level, the
deceleration time C1-01, C1-03, C1-05 or C1-07 will be used to decelerate. When the drive
output current falls below the value of P3-06 minus 2% for 100 ms, the drive accelerates back
to the frequency command at the active acceleration time.
2 : Enabled (Deceleration Time 2)
Same as P3-05 = 1 except the drive decelerates using the C1-03 deceleration time.
P3-06 Stall Prevention Level during Run
Sets the current level to activate the Stall Prevention function during run.
Stall Prevention Level during Run
□ Using Analog Input to Change Stall Prevention Level during Run
If E3-□□= 7 (Stall Prevention Level during Run) is set, this value can be changed via input
terminal A1.
The Stall Prevention level during run is determined by the smaller value of the P3-06 setting or
the input via terminal A1.
