seconds into the ramp, this command is issued with a Command Value of 4000. Therefore,
because one fourth of the original Ramp Time was remaining, one fourth of the new Ramp Time
(one fourth of 4000 milliseconds or 1000 milliseconds) will remain. So, the rest of the ramp will
take a full second.
A.2.8 Set Pressure Command
Character: ^
Decimal: 94
Hexadecimal: 0x5E
Command Value: Pressure Value
This command is used as the main command for regulating pressure. When this command is
issued, the current Mode, Pressure Set A, Pressure Set B, and Ramp Time are processed.
Additionally, the Command Value will be copied into the Command Pressure. There are two ways
that this command is used:
1. Use this command to set up the entry into pressure regulating mode. This command is used to
set up the target pressure curve before a command is issued to the position axis, which would
put the axis in pressure-monitoring mode. The axis will then only monitor the pressure and will
continue moving based on position until the pressure reaches Pressure Set A. At this point, the
pressure will be ramped to the Command Pressure that was specified in the Command Value
field of this command.
Note:
If this command was not issued before a command put the axis in pressure monitoring
mode, the Pressure Set A point may not be defined and the axis may begin ramping to an
undesired pressure immediately.
2. Use this command while in pressure regulating mode to ramp between two pressures. When the
axis is in pressure regulating mode, this command takes effect immediately and the axis begins
to ramp. To avoid a discontinuity in the pressure curve, this command should not be issued until
the previous pressure ramp is complete.
If this command is issued on a position-pressure axis, the behavior when the Actual Position
reaches the Command Position or the Extend Limit is as follows:
• The Target Pressure will begin decreasing. If the Actual Pressure goes below Pressure Set B, the
axis will exit pressure control.
A.2.9 Set Pressure Set A Command
Character: |
Decimal: 124
Hexadecimal: 0x7C
Command Value: Pressure Value
This command sets the Pressure Set A value to the Command Value. The new value for
Pressure Set A is used as soon as the command is processed. Refer to Pressure Set A for
