Note: To achieve maximum stroke time of 20 minutes for N=0, N=1 or 160
minutes for N=2, a set speed [S] cannot be used. The pump must be programmed
using the [V5] command.
c <n> Cutoff Speed in Pulses/Second
The [c] command sets the speed at which the plunger ends its movement, in
pulses/sec. The plunger will ramp down (slope) from the peak speed. The [c]
command overwrites the [C] command.

Note: [c] is only valid in a dispense move. During aspiration, [c] = [v].
Interaction of Set Commands
The Start Speed [v], Top Speed [V], and Cutoff Speed [c] commands interact
according to the following rules:
[v] < [c] < [V]
1
Start Speed should always be less than or equal to Top Speed. Changing the
Start Speed will change the Cutoff Speed if Cutoff Speed is less than the Start
Speed set. If the Start Speed [v] is greater than the Top Speed, the Start
Speed will be set equal to the Top Speed.
2
Top Speed should always be greater than or equal to the Start Speed and
Cutoff Speed. Changing the Top Speed will modify the Cutoff Speed and Start
Speed if they were improper, but will not modify the stored Start Speed. For
instance, values of 750, 100 and 1200 will cause the pump to run simply at the
top speed of 100.
3
Cutoff Speed [c] should always be less than or equal to Top Speed [V] and
greater than or equal to Start Speed [v]. Changing the Cutoff Speed will not
modify the Start Speed or Top Speed. However, if Cutoff Speed is greater than
Top Speed it will be ignored and the Cutoff Speed will be set equal to the Top
