Figure 4-10 and Figure 4-11 show the acceleration and deceleration performance of MCF8315C-Q1 when changing fan speed from 100->30% and 30->100%. The acceleration rate is as set in the EEPROM while the deceleration rate is lower of the following two values - determined by AVS (to prevent voltage spike on 24V rail) and EEPROM configured value. During acceleration/deceleration, the maximum current limit is set by EEPROM configured value to prevent over current condition.
