Output frequency frequency of acceleration and deceleration time Fundamental Set frequency F15.09 0 Actual acceleration time Actual deceleration time time Set acceleration Set deceleration Time t time Fig. 7-32 Schematic Diagram of Acceleration and Deceleration Time As shown in Fig. 7-32, the acceleration time is defined as the time of acceleration from 0.00 Hz to the reference frequency of acceleration/deceleration time; and the deceleration time is defined as the time of deceleration from the reference frequency of acceleration/deceleration time to 0.00 Hz.
The actual acceleration/deceleration time varies according to the ratio between the set frequency and reference frequency. The reference frequency of acceleration/deceleration time is set by function code F15.09 that represents the reference frequency of acceleration/deceleration time. If F15.09=0, the reference frequency depends on the function code F00.16 (maximum frequency). Assuming F00.16=100.00Hz, the acceleration (deceleration) time is expressed as the time for the output frequency to increase (decrease) from 0.00Hz (100.00Hz) to 100.00Hz (0.00Hz).
