FR500F Series Special Purpose Inverter
- 12 -
when inverter running into any step, timer starts, and running to this step by acce/dece time,
after reach the step, inverter continue to run as this step until timing arrived at the time set by
this step, running figure as below:

2. Gradual Mode
Gradual mode can set 16 multi-steps in total, also can set the time from current step to next
step. When running, inverter gradually change to next step from current step, total consuming
time is the set time. When PLC running finished, inverter will stop according to dece time, running

3: Length Mode
Frequency gradually changed from current speed to next setting speed, total consuming
length is set length(Length is calculated according to current frequency or to pulse input). When
PLC running finished, inverter stops according to the deceleration time, running diagram as
below:
