Allen-Bradley PowerFlex 70 Reference Manual

Speed Reference 2-175
Min/Max Speed
[Max Speed]
Maximum and minimum speed limits are applied to the reference. These
limits apply to the positive and negative references. The minimum speed
limits will create a band that the drive will not run continuously within, but
will ramp through. This is due to the positive and negative minimum speeds.
If the reference is positive and less than the positive minimum, it is set to the
positive minimum. If the reference is negative and greater than negative
minimum, it is set to the negative minimum. If the minimum is not 0,
hysteresis is applied at 0 to prevent bouncing between positive and negative
minimums. See below.
Maximum frequency
The maximum frequency defines the maximum reference frequency. The
actual output frequency may be greater as a result of slip compensation and
other types of regulation. This parameter also defines scaling for frequency
reference. This is the frequency that corresponds to 32767 counts when the
frequency reference is provided by a network.
