Stall Prevention Limit Level
Control Mode VF VFPG SVC Default: 50
Settings 0–100% (Refer to Pr.06-02, Pr.06-03)
 When the operating frequency is larger than Pr.01-01, Pr.06-02 = 150%, Pr.06-03 = 100% and Pr.06-15 =
80%:
Stall Prevention Level during acceleration = Pr.06-02 x Pr.06-15 = 150% x 80% = 120%.
Stall Prevention Level at constant speed = Pr.06-03 x Pr.06-15 = 100% x 80% = 80%.
