Rockwell Automation 160 SSC Series C FRN 7.xx - Manual (Page 45)

Parameters and Programming 5-7
38 [Boost Select]
Sets the boost voltage and redefines the Volts per Hz curve. Settings 0 – 8 can
provide increased torque at low frequency. Settings 9 – 12 are used to reduce
energy consumption.
0/12 Numeric
Value 2
39 [Skip Frequency]
Works in conjunction with P40 - [Skip Frequency Band] creating a range of
frequencies at which the drive will not operate continuously.
0/240 1 Hz 240 Hz
40 [Skip Frequency Band]
Determines the band around the P39 - [Skip Frequency] parameter. The actual
band width will be 2 times P40 - [Skip Frequency Band] - 1/2 the band above and
1/2 the band below. A value of zero will disable the skip frequency.
