Appendix B: Command Field Reference
B-17
The second type of ramp occurs when the axis enters pressure mode. In this case the pressure
is generally not at rest at the beginning. Therefore, for s-curve ramps, only the deceleration half
of the ramp is used and to ramp to a halt at the Command Pressure will take one half the
number of milliseconds given in the Ramp Time field. However, the whole Ramp Time will be
used in linear mode. For details on selecting s-curve versus linear ramps see the Ramp Mode
Type bit description.
There are two ways to set this field:
Issue a Set Pressure (^) command, and the fourth command parameter will be the new value for
Ramp Time.
Issue a Set Pressure Ramp Time (\) command, and the Command Value will be the new value
for Ramp Time.
Note: In the case where the Pressure Set A field is above the Command Pressure, the pressure
needs to be ramped in the reverse direction. In this case, the pressure is first accelerated and
then decelerated. The Ramp Time gives the entire length of this ramp. Do not divide this time by
two.
Note: Setting this field to zero will cause the Target Pressure to instantaneously jump to the
Command Pressure.
B.2.6 Command Value
Range: Depends on Command
The Command Value field is multipurpose. It is often used with the 'G' command to specify the
position where the axis is to move. When used this way, the value is checked to be within the
Extend Limit and Retract Limit and is then used as the Command Position value.
Here is the complete list of commands that use this field:
For this command: Command Value is:
