User Manual of EM730 Series Inverter 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). If F15.09=2, the reference frequency depends on the function code F18.01 (set frequency).
Assuming F18.01=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). acceleration/deceleration time terminals (19: acceleration and deceleration time terminal 1; 20: If the motor 1 is running at the normal (e.g. non-PLC/PID) speed (e.g. non-torque) and the 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- 34.
