Special
Acc/Dec (1 - 4) Settings
This parameter specifies the time in seconds for the drive to go from the
Maximum Frequency
to 0.0 Hz for the
Deceleration (Dec) 2 Profile
. The
Acceleration/Deceleration (Acc/Dec)
pattern may be set using
S-Curve Acc/
Dec Pattern 1

. The minimum
Acc/Dec
time may be set using
Acc/Dec
Time Lower Limit
(
.
This setting is also used to determine the deceleration rate of the
UP/DOWN
Frequency
functions.
Note:
A deceleration time shorter than the load will allow may cause
nuisance tripping and mechanical stress to loads.
Automatic Acceleration/Deceleration, Stall
, and
Ridethrough
settings
may lengthen the deceleration time.

Linear
acceleration and
deceleration is the default pattern
and is used on most applications.
S-Pattern 1
is used for applications
that require quick acceleration and
deceleration. This setting is also
popular for applications that require
