When the motor speed exceeds the
speed set in Pr. 374, overspeed (E.OS)
occurs, and the drive unit outputs are
stopped.
The above parameters can be set when Pr. 160 Extended function display selection = "0." (Refer to page 144)
∗1 Differs according to capacities. (0.2K to 2.2K/3.7K)
∗2 If a value exceeding 3000r/min is set, the actual rotation speed will be limited at 3000r/min.
