User Manual of A90 Series Inverter If the motor 1 is running at the normal (e.g. non-PLC/PID) speed (e.g. non-torque) and the acceleration/deceleration time terminals (19: acceleration and deceleration time terminal 1; 20: acceleration and deceleration time terminal 2) are invalid, the acceleration/deceleration time 1 and acceleration/deceleration time 2 can be switched by setting F15.10 to 1, as detailed in Fig. 7-33. Fig.
7-33 Schematic Diagram of Automatic Switching of Acceleration and Deceleration Time acceleration time 1 and 2 (F15.11), the acceleration time 1 will be the current valid During acceleration, if the output frequency is less than the switching frequency of the acceleration 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 During deceleration, if the output frequency is less than the switching frequency of the 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 233 Function Parameter Default Function code name Unit Attribute code description setting F15.13 Acceleration and deceleration time unit 0:0.01s 1:0.1s 2:1s 0 ○
