Sets the function to enable and disable Stall Prevention During Run.

Stall Prevention function during run prevents the motor from stalling by automatically reducing the speed when an oL1 [Motor Overload] occurs while the motor is running at constant speed.
Note:
-
An output frequency less than 6 Hz disables Stall Prevention during Run. The setting values of L3-05 and L3-06 [Stall Prevent Level during Run] do not have an effect.
-
The setting range changes when the A1-02 [Control Method Selection] value changes:
- 0
- No
-
The drive runs at the set frequency reference. A heavy load can cause the motor to stall and trip the drive with oC [Overcurrent] or oL1.
- 1
- Deceleration Time 1 (C1-02)
-
The drive will decelerate for the time set in C1-02 [Deceleration Time 1] when the current is more than the Stall Prevention level set in L3-06. When the current level is less than the “L3-06 setting value - 2%” for 100 ms, the drive accelerates again for the acceleration time applicable at that time until it is at the set frequency.
- 2
- Deceleration Time 2 (C1-04)
-
This setting functions the same as Setting 1 [Deceleration Time 1 (C1-02)]. When you enable the Stall Prevention function, the drive decelerates in the time set in C1-04 [Deceleration Time 2].
- 3
- Intelligent (Ignore Decel Ramp)
-
Enabled when A1-02 = 8 [EZOLV]. The drive operates with the largest possible output current to prevent motor stalling.
