• Upper speed limit is the value of Pr.1 for both forward and reverse rotations.

NOTE
• To perform speed limit by using terminal 1, calibrate terminal 1. (Refer to
 Speed limit mode 2 (Pr.1113 = "0" initial value)
• Following the polarity change in the torque command, the polarity of the speed limit value changes. This prevents the
speed from increasing in the torque polarity direction. (When the torque command value is 0, the polarity of the speed limit
value is positive.)
• When Pr.807 Speed limit selection = "0, 2", the setting during speed control is applied for the speed limit. When Pr.807
Speed limit selection = "1", Pr.808 Forward rotation speed limit/speed limit is applied for the speed limit.
