Plunger movements

Operating instructions
Set plunger resolution (increment) mode (N)
The resolution should be decided upon and set before programming
plunger moves. Normal resolution is adequate for most purposes.
Higher resolution is useful when greater precision in movement is
required, or very low velocity operation is needed.
The [N] command sets the resolution, that is, increments per stroke. It
allows you to select a higher resolution for plunger movement, position-
ing, and/or velocity in order to obtain finer control.
These settings also apply to position and velocity reporting.
Arguments:
Increment mode vs. full stroke:
<n> 0 N0, normal increment mode
1 N1, micro-increment mode for plunger positioning only, which is 8X resolu-
tion of normal increment mode. Plunger velocity settings remain in normal
increment mode.
2 N2, micro-increment mode for both positioning and velocity
{0} Power-up default
Increment
Mode Increments/full stroke,
C3000/C3000MP Increments/full stroke,
C24000/C24000MP
N0 3,000 increments 24,000 increments
N1 24,000 (8 * 3,000) 192,000 (8 * 24,000)
N2 24,000 (8 * 3,000) 192,000 (8 * 24,000)
Note:
• Changing between N0 or N1 mode and N2 mode does not automatically scale the
existing velocity and acceleration settings to maintain the same velocity/acceleration.
Thus, going to N2 from N0 or N1 without changing the velocity/acceleration settings
will cause the plunger to move 8 times slower. Also note that going from N2 mode to
N1 or N0 mode without changing the velocity/acceleration settings can result in set-
tings that are not advisable.
• For consistency in initialization, it is recommended that initialization always be per-
formed in normal (N0) mode.
• These parameters may be changed with the [u] command. However, it is recom-
mended that Customer Service be consulted before making any changes with the
[u] command. Otherwise unwanted pump behavior can result.
