CAVRO XP 3000 - c <n> CUTOFF VELOCITY IN HZ; C <n> CUTOFF VELOCITY IN STEPS; Report Commands

Software Communication 3-39
NOTE To achieve maximum stroke time (20 minutes or 1200 seconds), you must use
the [V5] command.
c <n> CUTOFF VELOCITY IN HZ
The [c] command sets the velocity at which the plunger ends its movement. The plunger
will ramp down (slope) from the peak velocity. The [c] command overwrites the [C]
command. The syntax for this command is:
[c<n>], where <n> = 50..2700 Hz
(900 is the default; 901 is the default on the 3-port distribution valve)
NOTE [c] is only valid in a dispense move. During aspiration [c] = [v].
C <n> CUTOFF VELOCITY IN STEPS
During the last phase of a plunger move, the speed ramps down (as defined by the
programmed slope) toward the cutoff velocity [c]. When cutoff steps are specified, the
plunger stops at <n> steps before reaching the cutoff velocity. The total number of steps
required by the plunger movement is maintained by adding <n> steps to the second phase
(top velocity) of the plunger move. The syntax of this command is:
[C<n>], where <n> = 0..25 steps (0 is the default)
The [C] command overwrites the [c] command and resets cutoff velocity to start velocity.
For example, [C5] stops the plunger five steps short of the final velocity. The total
number of steps is automatically maintained by adding five steps to the second phase of
plunger movement. In other words, the deceleration phase of the move is shortened by
five steps and the constant speed phase is lengthened by five steps.
Report Commands
Report commands do not require an [R] command.
NOTE All Report commands are invalid in CAN communication. The frame type 6 is
provided to retrieve information from the pump. For more information, see
Appendix F, “CAN Communication Commands.”
