6-7-2 Switch Acceleration Time and Deceleration Time in Two Stages
Precautions for Correct Use
Set, as the acceleration time, the time that it takes to rise from 0 Hz to the maximum frequency;
and set as the deceleration time, the time that it takes to fall from the maximum frequency to 0
Hz. Each of the set times is the corresponding one of the following values.
Acceleration time 1: Calculated value from [AC120];
Deceleration time 1: Calculated value from [AC122];
Acceleration time 2: Calculated value from [AC124]; and
Deceleration time 2: Calculated value from [AC126].
You can use [AC115] to select one of the following three methods of switching the acceleration or
deceleration time:
• Switching by the Input terminal function [2CH];
• Automatically switching by any given frequency; and
• Automatically switching only at the time of switching between the forward revolution and the back-
ward revolution.
Described below is an exemplar case of switching between the acceleration or deceleration time 1 and
the acceleration or deceleration time 2.
