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:

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.

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.
