L3-01

(48FH)

Stall Prevention Selection during
Acceleration

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.

Default: 1

Min: 0
Max: 2

217

L3-02

(490H)

Stall Prevention Level during
Acceleration

Used when L3-01 = 1 or 2. 100% is equal to the drive rated current.

Default:

<16>

Min: 0%
Max: 150%

<16>

219

L3-05

(493H)

Stall Prevention Selection during
Run

0: Disabled. Drive runs at a set frequency. A heavy load may cause speed loss.
