Parameter Reference D-139
AC30 series Variable Speed Drive
Parameter Name
No.
Path
Default
Range
Units
Writable
Symmetric Mode
0488
Parameters::Motor Control::Ramp
FALSE
ALWAYS
Select whether to use Acceleration Time and Deceleration Time pair of ramp rates, or to use Symmetric Time to define the ramp
rate for the Drive.
Ramp Type
0485
Parameters::Motor Control::Ramp
0
0:LINEAR
1:S RAMP
ALWAYS
Selects the ramp type
Symmetric Mode
0488
Parameters::Motor Control::Ramp
FALSE
ALWAYS
Symmetric Time
0489
Parameters::Motor Control::Ramp
10.000
0.000 to 3000.000
s
ALWAYS
The time that the Drive will take to ramp from 0.00% to 100.00% and from 100.00% to 0.00% when Symmetric Mode is TRUE.
Sramp Continuous
0490
Parameters::Motor Control::Ramp
FALSE
ALWAYS
When TRUE, and S ramp is selected in Ramp Type, forces a smooth transition if the speed setpoint is changed when ramping. The
curve is controlled by the Sramp Acceleration and Sramp Jerk1 to Sramp Jerk 4 parameters. When FALSE, there is an immediate
transition from the old curve to the new curve.
Sramp Acceleration
0491
Parameters::Motor Control::Ramp
10.0
0.0 to 100.0
%/s²
ALWAYS
Sets the acceleration rate in units of percent per second², i.e. if the full speed of the machine is 1.25m/s then the acceleration will be:
1.25 x 75.00% = 0.9375m/s²
Sramp Deceleration
0492
Parameters::Motor Control::Ramp
10.0
0.0 to 100.0
%/s²
ALWAYS
This functions in the same way as Sramp Acceleration above.
