Inverter Function
• 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
backward revolution.
• Described below is an exemplar case of switching
between the acceleration or deceleration time 1
and the acceleration or deceleration time 2.
• 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].
