Parameter Descriptions
JERK 1 to JERK 4
Rate of change of acceleration for the relevant segment of the curve, i.e. JERK 1 is for segment 1, etc.
CONTINUOUS
When TRUE, it forces a smooth transition if the speed point is changed when ramping. The curve is controlled by the
ACCELERATION and JERK 1 to JERK 4 parameters. When FALSE, there is an immediate transition from the old curve to
the new curve.
HOLD
When TRUE, the output of the ramp is held at its last value.
SYMMETRIC JERK
When TRUE, JERK 1 is used for all segments of the curve. JERK 2, JERK 3 and JERK 4 are ignored.
RESET
If TRUE, the output is made equal to the input.
OFFSET
This input provides an additional offset to be applied to the Position Output
MAX SPEED
This parameter specifies the maximum speed of the Virtual Master
SPEED FILT TIME
When SOURCE is set to FEEDBACK POSN or REFERENCE ENCODR, the speed if filtered by the value set by this
parameter.
ACCEL FILT TIME
When SOURCE is set to FEEDBACK POSN or REFERENCE ENCODR, the acceleration is filtered by the value set by this
parameter.
POSITION OUTPUT
Master position output.
