* 1. Factory settings will vary based on drive capacity (values given here are for 208-240Vac, 0.4kW).
* 2. Setting value for 208-240Vac. Double the value when working with 380-480Vac drives.
* 3. When set to zero, the motor will accelerate to the speed set acceleration time (C1-01 thru C1-08).
Stall Prevention: L3
User parameters for the stall prevention function are shown in the following table.

Set the time (in seconds) to

then active acceleration time is
used instead.

Stall
Prevention
Selection
During
Accel
Selects the stall prevention
method used to prevent
excessive current during
acceleration.
0: Disabled - Motor
accelerates at active
acceleration rate. 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. Acceleration will
continue when the output
current level falls below the
L3-02 level.
2: Intelligent - The active
acceleration rate is ignored.
Acceleration is completed
in the shortest amount of
time without exceeding the
current value set in L3-02.
