User Manual of EM730 Series Inverter time; otherwise, the acceleration time 2 will be the current valid acceleration time. deceleration time 1 and 2 (F15.12), the deceleration time 1 will be the current valid deceleration During deceleration, if the output frequency is less than the switching frequency of the 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 . The frequency hopping function (FH function for short) can prevent the output frequency of the inverter from the mechanical resonance frequency point of the mechanical load. If the inverter is prohibited from running at a constant speed within the frequency hopping range, hopping will not occur during acceleration. Instead, the inverter will run smoothly.
