401 Ramp Select
Default: ART DI
Range: n/a
Level: 2
The
Ramp Select
parameter configures when the alternate ramps of the drive will be active and whether the drive
ramps to stop, or coasts to stop. The following data values may be assigned to this parameter:
Parameter Value
Type of Ramp
Ramp Configured by:
ART-DI
Ramp-to-Stop
403 (Decel Time 1); 404 (Accel Time 2)
and
(Decel Time 2); 415 (Accel Time 3)
and
416 (Decel Time 3); 417 (Accel Time
and
These are all based on digital inputs configured in
AltRamp and AltRamp2 (see parameter
727, MOL Configure
and
AltRamp2
.
ART-F/R
Ramp-to-Stop
Running forward:
and
Running reverse:
and
ART-Frq
Ramp-to-Stop
If the output frequency is less than preset frequency parameter
308 (Preset Freq
6)
, the active ramp is set by
. If the
output frequency is equal to or greater than
308 (Preset Freq 6)
, the active ramp
is set by
and
.
ART-Strt/RS
Ramp-to-Stop
This setting uses the Alternate Ramp for Acceleration (parameter
speed, then uses the Main ramps (parameters
and
403
are adjusted. The drive will revert to the Alternate Decel ramp (parameter
)
when a Stop command is given.
S-Curve
Ramp-to-Stop
The drive uses
for total time and
as the S Ramp Rounding value. The amount of rounding is the same for that
start and stop of the ramp time.
ART-DI CTS
Coast-to-Stop
Same as ART-DI but with Coast-to-Stop
ART-F/R CTS
Coast-to-Stop
Same as ART-F/R but with Coast-to-Stop
ART-Frq CTS
Coast-to-Stop
Same as ART-Frq but with Coast-to-Stop
ART-Str/CS
Coast-to-Stop
Same as ART-Strt but with Coast-to-Stop
S-Curve CTS
Coast-to-Stop
Same as S-Curve but with Coast-to-Stop
402 Accel Time 1
Default: 5.0 s
Range: 0.1 to 3200.0 s
Levels 1,2
This parameter configures the default length of time to accelerate from 0 Hz to the value of parameter
. This acceleration ramp is selected by parameter
401 (Ramp Select)
.
Note that extremely short acceleration times may result in nuisance fault trips.
403 Decel Time 1
Default: 5.0 s
Range: 0.1 to 3200.0 s
Levels 1,2
This parameter configures the default length of time to decelerate from the value of parameter
302
(
Max Frequency
to 0 Hz. The deceleration ramp is selected by parameter
401
(
Ramp Select
).
Note that extremely short deceleration times may result in nuisance fault trips or may require an external dynamic brake
or regen current limit.
