S <n> Set Speed
The [S] command sets a predefined top plunger speed, in pulses/sec. As <n>
increases, the plunger speed decreases.

These speed settings do not cover the full range of speeds the plunger can travel.
They are commonly used speeds provided for the convenience of the user. All
times are approximate and will vary with different ramp speeds and cutoffs. Tecan
Systems also provides a utility for performing theoretical speed calculations in
Pump:Link Evaluation Software (in the Utility menu on the user interface). For
information on determining timing for specific applications, see Appendix B,
"Plunger Information".
The [S] command sets top speed without changing start speed, slope, and cutoff
speed, except under the following conditions:
If the start speed is higher than the (new) top speed, start speed is changed to
equal the top speed.
If the cutoff speed is higher than the (new) top speed, cutoff speed is changed
to equal the top speed.
Speed codes, the Hz (pulses/second) equivalent, and seconds per stroke are
listed below. Seconds/stroke values are based on default ramping.
