Fig. 7-34 Schematic Diagram of Automatic Switching of Acceleration and Deceleration Time
During acceleration, if the output frequency is less than the switching frequency of the
acceleration time 1 and 2 (F15.11), the acceleration time 1 will be the current valid acceleration
time; otherwise, the acceleration time 2 will be the current valid acceleration time.
During deceleration, if the output frequency is less than the switching frequency of the
deceleration time 1 and 2 (F15.12), the deceleration time 1 will be the current valid deceleration
time; otherwise, the deceleration time 2 will be the current valid deceleration time.
Under different working conditions, the acceleration and deceleration time requirements
may vary greatly. The system provides three acceleration and deceleration time units, depending
on the function code F15.13. F15.13=1 means that the acceleration/deceleration time unit is
“0.1s”. Except for that in torque control (F13.06), all the acceleration and deceleration time will
change. For example, the value of F00.14 will change from 15.00s to 150.0s by default.
