* 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).

Accel
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
L3-01
output current exceeds
L3-02 level, acceleration
stops. Acceleration will

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.
