Parameter Descriptions
JERK 1 to JERK 4
PREF: 118.04, 118.05,
118.06, 118.07
Default: 10.00 /s² Range: 0.00 to 100.00 /s 3
Rate of change of acceleration for the relevant segment of the curve, i.e. JERK 1 is for segment 1, etc.
CONTINUOUS
PREF: 118.08 Default: FALSE Range: FALSE / TRUE
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
PREF: 118.09 Default: FALSE Range: FALSE / TRUE
When TRUE, the output of the ramp is held at its last value.
SYMMETRIC JERK
PREF: 118.10 Default: FALSE Range: FALSE / TRUE
When TRUE, JERK 1 is used for all segments of the curve. JERK 2, JERK 3 and JERK 4 are ignored.
RESET
PREF: 118.11 Default: FALSE Range: FALSE / TRUE
If TRUE, the output is made equal to the input.
OFFSET
PREF: 118.12 Default: 0.0000 deg Range: 0.0000 to 360.0000
deg
This input provides an additional offset to be applied to the Position Output
MAX SPEED
PREF: 118.18 Default: 1500.0 rpm Range: 100.0 to 6000.0 rpm
This parameter specifies the maximum speed of the Virtual Master
SPEED FILT TIME
PREF: 118.22 Default: 5.0 ms Range: 0.00 to 100.0 ms
When SOURCE is set to FEEDBACK POSN or REFERENCE ENCODR, the speed if filtered by the value set by this
parameter.
ACCEL FILT TIME
PREF: 118.23 Default: 5.0 ms Range: 0.00 to 100.0 ms
When SOURCE is set to FEEDBACK POSN or REFERENCE ENCODR, the acceleration is filtered by the value set by this
parameter.
