D-90 Parameter Reference
AC30V series Variable Speed Drive
PNO Parameter Descriptions
0486 Acceleration Time
The time that the Drive will take to ramp the setpoint from 0.00% to 100.00% when Ramp Type is LINEAR.
0487 Deceleration Time
The time that the Drive will take to ramp the setpoint from 100.00% to 0.00% when
is LINEAR.
0488 Symmetric Mode
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.
0489 Symmetric Time
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.
0490 Sramp Continuous
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.
0491 Sramp Acceleration
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
0492 Sramp Deceleration
This functions in the same way as Sramp Acceleration above.
0493 Sramp Jerk 1
Rate of change of acceleration for the first segment of the curve in units of percent per second³, i.e. if the full speed of the machine is
1.25m/s then the jerk will be:
1.25 x 50.00% = 0.625m/s³
0494 Sramp Jerk 2
Rate of change of acceleration in units of percent per second³ for segment 2
0495 Sramp Jerk 3
Rate of change of acceleration in units of percent per second³ for segment 3
0496
Sramp Jerk 4
Rate of change of acceleration in units of percent per second³ for segment 4
0497 Ramp Hold
When TRUE the output of the ramp is held at its last value
