1. Set Prohibited Frequency Range 1 Low Limit (P3.7.1) to a value of 44.5.
2. Set Prohibited Frequency Range 1 High Limit (P3.7.2) to a value of 45.5.
NOTE:
The drive will still ramp through these speeds, but will not control within this
range. The speed at which the drive ramps through this range can be changed by
the Ramp Time Factor (P3.7.7) to make it faster.
For example. If Acceleration Time 1 (P3.4.2) is set to a value of 120, Minimum
Frequency (P3.3.1) is set to a value of 0, and Maximum Frequency (P3.3.2) is
set to a value of 60; then it takes 2 seconds to speed up 1 hertz. If Ramp Time
Factor (P3.7.7) is set to a value of 2, then it takes 1 second to speed up 1 hertz
when within the range as defined by Prohibited Frequency Range 1 Low Limit
(P3.7.1) and Prohibited Frequency Range 1 High Limit (P3.7.2)
Limit supervisions (M3.8)
Two signal values can be selected for supervision. High or low limits are supervised.
The limit supervisions settings are presented in the following table:
