Performance
The
jog
acceleration
rate
is
only
used
when
accelerating
towards
the
jog
reference
and
when
changing
the
jog
reference.
The
acceleration
rate
is
selected
as
follows:
such
that
ramp
rates
can
be
selected
by
external
control.
The
ramp
rate
selected
depends
on
the
bi
nary
code
generated
by
these
bits
as
follows:
When
Pr
2.20
is
set
to
9
the
appropriate
deceleration
rate
is
automatically
selected
depending
on
the
value
of
Pr
1.50
,
and
so
a
deceleration
rate
can
structure

NOTE
Using low values (e.g. 0.100), can cause FbL trips. To avoid trips, increase Pr 3.56 Speed feedback loss window.
0 Ramp rate selection by terminal input
1-8 Ramp rate defined by parameter number, i.e. 1 = Pr 2.21 { SE04, 0.25 }, 2 = Pr 2.22 , etc.
9 Ramp rate selection by Pr 1.50
When Pr 2.20 is set to 0 the deceleration ramp rate selected depends on the state of bit Pr 2.35 to Pr 2.37 . These bits are for control by digital inputs
be programmed to operate with each reference. Since the new ramp rate is selected with the new reference, the deceleration applies towards the
selected preset if the motor needs to decelerate to reach the preset.
