For detailed information about setting up Keeper parameters, see
401 Ramp Select
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
ART-DI
ART-F/R
ART-Frq
ART-Strt/RS
S-Curve
ART-DI CTS
ART-F/R CTS
ART-Frq CTS
ART-Str/CS
S-Curve CTS

402 Accel Time 1

This parameter configures the default length of time to accelerate from 0 Hz to the value of parameter 302
(Max Frequency). This acceleration ramp is selected by parameter 401 (Ramp Select).
Note that extremely short acceleration times may result in nuisance fault trips.

Ramp Configured by:
402 (Accel Time 1) and 403 (Decel Time 1); 404
(Accel Time 2) and 405 (Decel Time 2); 415 (Accel
Time 3) and 416 (Decel Time 3); 417 (Accel Time 4)
and 418 (Decel Time 4). These are all based on
digital inputs configured in AltRamp and AltRamp2
(see parameter 727, MOL Configure). See also the
note on page 85 about AltRamp and AltRamp2.
Running forward: 402 (Accel Time 1) and 403

(Decel Time 1)

Running reverse: 404 (Accel Time 2) and 405 (Decel
Time 2)
If the output frequency is less than preset
frequency parameter 308 (Preset Freq 6), the
active ramp is set by 402 Accel Time 1 and 403
Decel Time 1. If the output frequency is equal to or
greater than 308 (Preset Freq 6), the active ramp is
set by 404 (Accel Time 2) and 405 (Decel Time 2).
This setting uses the Alternate Ramp for
Acceleration (parameter 404) to the set speed, then
uses the Main ramps (parameters 402 and 403)
when the speeds are adjusted. The drive will revert
to the Alternate Decel ramp (parameter 405) when
a Stop command is given.
The drive uses 402 (Accel Time 1) and 403 (Decel
Time 1) for total time and 414 as the S Ramp
Rounding value. The amount of rounding is the
same for that start and stop of the ramp time.
