5.1.1 Automatic acceleration/deceleration
In this mode, the acceleration and deceleration times are changed automatically
according to the load applied.
=
*
The acceleration and deceleration times are adjusted automatically within a range of
1/8 to 8 times longer than the times set with the
and the
, respectively.
Set the parameter
(automatic acceleration/deceleration) at

☆
When the automatic acceleration/deceleration is selected (enabled), the acceleration/deceleration times
constantly change according to the load condition. So, use the manual setting(
,
) for machines
that need to be accelerated and decelerated always at constant rates.
☆
Set manually the acceleration and deceleration times (
=
) in the case that braking resistor or
braking unit is applied (
=
).
☆
For a load that requires the inverter to be operated almost at its rated current, the motor may fail to reach
the specified speed within the specified time. In such a case, set manually the acceleration and
deceleration times (
=
).
☆
Before setting this parameter, connect the inverter to the motor.
5. Explanation of the basic parameters
・
Function
1)The acceleration time parameter
is to set the time in which the inverter's output
frequency goes up from 0 Hz to the maximum frequency
.
2)The deceleration time parameter
is to set the time in which the inverter's output
frequency goes down from the maximum frequency
to 0 Hz.
