Parameters of Stall Protection (P9.4 to P9.6)
The motor Stall Protection protects the motor from short time overload situations such as one caused
by a stalled shaft. The stall state is defined with two parameters, P9.5 (Stall Time) and P9.6 (Stall Fre-
quency Limit). If the current is as high as the P1.5 (Current Limit) and the current limiter has reduced
the output frequency below the P9.6 for the time P9.5 than the set limit the stall state is true. There is
actually no real indication of the shaft rotation. Stall Protection is a type of overcurrent protection.
