3 ACC2=10.0%/s
SECOND ACCELE
G5.3 /
Acceleration
ramp 2
0.01 – 650%
/ sec
Allows user to set the alternative acceleration ramp. The setting is based in
acceleration units (increase in percentage of speed per second), like the main
ramp setting. The drive will apply acceleration ramp 1 until motor speed exceeds
the value set in 'G5.5 BRK ACC'. From here on it will apply the alternative ramp
value. If 'G5.5 BRK ACC = OFF' no ramp change will occur.
YES
4 DECEL2=10.0%/s
SECOND DECELE
G5.4 /
Deceleration
ramp 2
0.01 – 650%
/ sec
Allows user to set the alternative deceleration ramp. The setting is in deceleration
units (decrease in percentage of speed per second), like the main ramp setting.
The drive will apply deceleration ramp 2 until motor speed is below the value set
in 'G5.6 BRK DEC'. From here on it will apply the alternative ramp value. If 'G5.6
BRK DEC = OFF' no ramp change will occur.
Note: For drives which input voltage is 400V, the default values will be:
- From 6A to 48A =10%/sec
- From 60A to 170A =5%/sec
- From 210A to Imax =2%/sec
YES
5 BRK ACC=OFF
BREAKPOINT ACL
G5.5 / Speed for
acceleration
ramp change
OFF,
0 to 250%
This parameter sets the break frequency for the alternative acceleration ramp.
This parameter should be set at to the speed at which a change in the
acceleration profile is required. If this value is exceeded the drive will start to apply
the value of the alternative acceleration ramp.
Note: Alternative acceleration and deceleration can be selected through the digital
inputs or comparator output functions. This functionality is independent of the
drive speed (for example, if the magnitude of the comparator is the drive rated
current, when the drive output current exceeds a defined level, calculated as % of
In, a ramp change occurs).
YES
6 BRK DEC=OFF
BREAKPOINT DCL
G5.6 / Speed for
deceleration
ramp change
OFF,
0 to 250%
This parameter sets the break frequency for the alternative deceleration ramp.
This parameter should be set at to the speed at which a change in the
deceleration profile is required. If this value is exceeded, the drive will start to
apply the value of the alternative deceleration ramp.
Note: Alternative acceleration and deceleration can be selected as needed
through the digital inputs or comparator output functions. This functionality is
independent of the drive speed (for example, if the magnitude of the comparator is
the drive rated current, when the drive output current is below a defined level,
calculated as % of In, a ramp change occurs).
YES
7 MP I1=1.0%/s
MOTO POT INC1
G5.7 / Ramp 1 of
reference
increase for
motorized pot.
0.01 – 650%
/ sec
Allows adjustment of ramp 1 reference increase when using the motorized
potentiometer function.
YES
8 MP D1=3.0%/s
MOTO POT DEC1
G5.8 / Ramp 1 of
reference
decrease for
motorized pot.
0.01 – 650%
/ sec
Allows adjustment of ramp 1 reference decrease when using the motorized
potentiometer function.
YES
9 MP I2=1.0%/s
MOTO POT INC2
G5.9 / Ramp 2 of
reference
increase for
motorized
potentiometer
0.01 – 650%
/ sec
Allows user to set the ramp 2 reference increase for the motorized potentiometer
function. The drive will apply the ramp 1 rate until the value set in 'G5.11 PMOT
BRK' is exceeded. From here on it will apply the alternative ramp value. If 'G5.11
PMOT BRK = OFF', no ramp change will occur.
YES
10 MPD2=3.0%/s
MOTO POT DEC2
G5.10 / Ramp 2
of reference
decrease for
motorized
potentiometer
0.01 – 650%
/ sec
Allows user to set the ramp 2 reference decrease for the motorized potentiometer
function. The drive will apply the ramp 1 rate until below the value set in 'G5.11
PMOT BRK'. From here on it will apply the alternative ramp value. If 'G5.11 PMOT
BRK = OFF', no ramp change will occur.
YES
11 MPOTBRK = OFF
MOTO POT BRKPOIN
G5.11 / Speed
for ramp change
with motorized
pot.
OFF=0 to
250%
This parameter sets the break frequency for the alternative acceleration and
deceleration reference ramp when using motorized potentiometer. This parameter
is the speed at which the change in motorized potentiometer reference ramp
profile takes place.
YES
12 SP FLT= OFF
SMOOT SPD FILTER
G5.12 / Time
constant to filter
the speed
OFF, 0.0 –
80.0%
Percentage of the acceleration ramp where the S - filter will be applied. S-Curve
can be introduced if smoother performance during acceleration and deceleration
is required. S-Curve introduces a filter for speed reference changes during
‘Start/Stop’ and acceleration and deceleration. It is especially useful in cranes and
elevators.
YES
