ation Pattern
Parameter
Setting an acceleration or deceleration pattern is possible that suit each system.
Setting the acceleration pattern selection and the deceleration pattern selection can be done inde-
pendently by [AC-03] and [AC-04], respectively.
To use an acceleration or deceleration pattern other than the linear one (00), a stable operation can be
achieved by an command that can fix the target of the frequency command by means of the LCD oper-
ator command and/or the multi-speed command.
Even if an acceleration or deceleration pattern is set, the acceleration time should be set at the time
that it takes to rise from 0 Hz to the maximum frequency and the deceleration time should be set at the
time it takes to fall from the maximum frequency to 0 Hz.
Calculation of the acceleration or deceleration pattern is performed from the minimum frequency (the
command frequency) to the command frequency (the minimum frequency) when an inverter is started
or stopped. In control mode in which the minimum frequency is disable, the calculation that ignores the
minimum frequency is performed.
Precautions for Correct Use
• Changing the acceleration or deceleration pattern from one to another will create a sector
with a(n) acceleration or deceleration time having a steep gradient. If the occurrence of an
over current/over voltage is predicted, the acceleration or deceleration time has to be
adjusted to prevent such an occurrence.
• When any other acceleration or deceleration pattern than the linear one (00) is set, a change
of command value during the acceleration or deceleration may cause a recalculation of the
acceleration or deceleration pattern, which may result in a shock.
• When any other acceleration or deceleration pattern than the linear one (00) is set, use any
other command than the analog input one. An unsteady command value may cause a recal-
culation of the acceleration or deceleration pattern, which may prolong the actual accelera-
tion or deceleration time.
