0: Disabled.
1: General purpose. Acceleration is paused as long as the current is above the L3-02
setting.
2: Intelligent. Accelerate in the shortest possible time without exceeding the L3-02
level.
Used when L3-01 = 1 or 2. 100% is equal to the drive rated current.
0: Disabled. Drive runs at a set frequency. A heavy load may cause speed loss.
1: Decel time 1. Uses the deceleration ramp set to C1-02 while Stall Prevention is
performed.
2: Decel time 2. Uses the deceleration ramp set to C1-04 while Stall Prevention is
performed.
Enabled when L3-05 is set to 1 or 2. 100% is equal to the drive rated current.
L4-01 sets the speed detection level for digital output functions H2- = 3, 4, 5.
L4-02 sets the hysteresis or allowable margin for speed detection.
L4-03 sets the speed detection level for digital output functions H2- = 13, 14, 15,
16.
L4-04 sets the hysteresis or allowable margin for speed detection.
0: Stop. Drive stops when the speed reference is lost.
1: Run. Drive runs at a reduced speed when the speed reference is lost.
Sets the percentage of the speed reference that the drive should run with when the
speed reference is lost.
0: No detection during baseblock.
1: Detection always enabled.
Sets the door zone speed level. The "door zone" multi-function digital output is closed
when the speed falls below this level.
