IMPULSE•G+ Mini Advanced Instruction Manual – March 2014
5-66
When a motor is used above rated speed (E01.06), the output characteristics change from constant
torque to constant HP (See Figure 5-27). During acceleration above rated speed, the stall prevention
current limit level is automatically reduced for smoother acceleration. The parameters (L03.02 and
L03.03) limit the stall prevention current limit level in this region. The current limit during
acceleration is changed according to the following equation:

This function automatically adjusts the output frequency, acceleration and/or deceleration
rates in order to continue operation without tripping or “stalling” the inverter.
