Parameter Reference
D-90
AC30V series Variable Speed Drive
PNO Parameter Descriptions
Acceleration Time
The time that the Drive will take to ramp the setpoint from 0.00% to 100.00% when
Ramp Type
is LINEAR.
Deceleration Time
The time that the Drive will take to ramp the setpoint from 100.00% to 0.00% when
Ramp Type
is LINEAR.
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.
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.
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.
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
Sramp Deceleration
This functions in the same way as
Sramp Acceleration
above.
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
Sramp Jerk 2
Rate of change of acceleration in units of percent per second³ for segment 2
Sramp Jerk 3
Rate of change of acceleration in units of percent per second³ for segment 3
Sramp Jerk 4
Rate of change of acceleration in units of percent per second³ for segment 4
Ramp Hold
When TRUE the output of the ramp is held at its last value
