Figure 1.80 Stall Prevention during Acceleration for Permanent Magnet Motors
Setting 2: Intelligent Stall Prevention
When L3-02 = 2, the drive will disregard the selected acceleration time and try to accelerate
in the minimum time. The acceleration rate is adjusted so that the current does not exceed
the value set in parameter L3-02.
■
L3-02: Stall Prevention Level during Acceleration
Sets the output current level at which the Stall Prevention during acceleration is activated.
• If stalling occurs with L3-02 set to its default value when using a motor that is relatively
small compared to the drive, try lowering L3-02.
• When operating the motor in the constant power range, also set parameter L3-03.
■
L3-03: Stall Prevention Limit during Acceleration
The Stall Prevention level is automatically reduced when the motor is operated in the
constant power range. L3-03 sets the lower limit for this reduction as a percentage of the
drive rated current.
No.
<1> The upper limit and default value is determined by the duty rating and the carrier frequency derating selection
(C6-01 and L8-38 respectively).
