Stall Prevention Limit Level (Weak Magnetic Area Current Stall Prevention Level)
Default: 100
Settings 0–100% (Refer to Pr. 06-03, Pr. 06-04)
Sets the over-current stall prevention level when operation frequency is larger than Pr.01-01. This
parameter only works during acceleration.
Example: Pr. 06-03 = 150%, Pr. 06-04 = 100% and Pr. 06-16 = 80%, when the operation
frequency is larger than Pr. 01-01, the over-current stall prevention Level during acceleration is:
Pr. 06-03 × Pr. 06-16 = 150 × 80% = 120%.
Pr. 06-16 is invalid when the over-current stall prevention activates according to Pr. 06-04 at
constant speed.
