Cavro® XLP 6000 Modular Syringe Pump Operating Manual, 734237-C, en
Note: Unless the top speed is less than or equal to the start or cutoff speed,
always program the pump in order of the move: start speed [v], top speed [V],
cutoff speed [c].
Changing Speed on the Fly
Speed changes can be made while the syringe plunger is moving. This is called
"changing speed on the fly."
Speeds can be decreased or increased between 5 and 750 Hz (i.e., in the fine
positioning region).
To change speed on the fly:
1 Issue speed commands with identical start and top speeds (e.g., [v100V100]),
followed by a Plunger Move command. Ramping is not allowed in on-the-fly
changes.
2 Issue a new top speed in the range 5 to 750 (e.g. [V600]) while the plunger is
moving, to change the speed on the fly.
Note: When the move completes, speed values revert to original values (i.e.,
value sent on-the-fly is temporary).
Note: When changing speed on the fly in CAN, use frame type 0.
L <n> Set Slope
During the beginning and end of a move, the plunger speed ramps up and
down respectively. The ramp is programmed using the Slope command. It is
calculated as <n> x 2.5 pulses/sec
[L<n>]
where <n> = 1..20 (7 is the default)
In normal or fine positioning modes (N0, N1) pulses are in half steps. In micro-
step mode (N2) pulses are in micro-steps.
