Functions and Parameters
12.8.6 Acceleration and Deceleration Setting
This function defines the configuration of acceleration and deceleration process.

E0.26 Acceleration time
E0.27 Deceleration time
E0.28 S-curve starting phase factor
E0.29 S-curve stopping phase factor
'Acceleration time' is the time for frequency increase from 0.00 Hz to [E0.08]
'Maximum output frequency'.
'Deceleration time' is the time for frequency decrease from [E0.08] 'Maximum
output frequency' to 0.00 Hz.
Fig. 12-55: Acceleration and deceleration time
There are eight groups of acceleration / deceleration time which is selected with
external control terminals. Group E0.26 and E0.27 is used as default value if no
acceleration / deceleration time terminal is defined. For using of other accelera-
tion / deceleration time which is defined by E3.10...E3.23, up to three terminals
of E1.00...E1.04 and H8.00...H8.04 should be selected to '10: Acceleration / de-
celeration time 1 activation', '11: Acceleration / deceleration time 2 activation'
and '12: Acceleration / deceleration time 3 activation'. See
"Simple PLC and Multi-Speed Setting" on page
Two curve modes are available for acceleration / deceleration which is defined
by [E0.25] : 'linear curve' and 'S-curve'.
[E0.25] = 0: Linear mode
