• Check the deadband. This system has a very small deadband, approx 5
millivolts, so we will not worry about it.
• Set the gains and feed forwards to zero and issue a Set Parameters (P)
command.
• Double-click the Axis 0 Auto Stop word (in the Parameters field).
− Set the Overdrive, Integrator Windup and Overdrive bits to Status
only.
• Set the proportional gain to a small value, such as 5. Issue a Set
Parameters (P) command.
• Set the Plot Time for Axis 0 to 4.
• Now make a move. The tuning process will consist of repeatedly making
moves. To easily make repeated moves, use Stored Commands:
− To edit and view the Stored Commands, click Stored Command
Editor on the Stored Commands menu. The following window
appears:
− For example, ALT-1 on axis 1 will issue a Go cmd to 4000 at a speed
of 10 in/sec, with acceleration rates of 100 in/(sec*sec). These are
common values for moving hydraulic systems. These values are
editable from this window.
− To use the stored commands, click on any Axis 0 field, then press e.g.
ALT-1 to move to 4 in. and ALT-5 to move to 20 in. The command
will be issued to the axis where the cursor is located.
• Using the Stored Commands, a move is made in this example from 2 in. to
8 in. The move will take less time than what the Plot Time is set to so that
the entire move can be viewed.
• Press the Insert key. This opens the Plot window with the last move. It
looks like this:
