HTACHANNEL = 6 : REM Use analog channel 6

HTADEADBAND = 2 : REM Ignore errors of 2 or under

HTAFILTER = 0.2 : REM Set a low analog filter value

HTAGAIN = 0.03 : REM set the gain term

HTADAMPING = 0.2 : REM Set the damping term

ACCEL = 200 : REM Set maximum accel rate

DECEL = 300 : REM Set maximum decel rate

SPEED = 20 : REM Set maximum move speed

HOLDTOANALOG = 25 : REM set the hold value to 25%

GO : REM Start the move

The above example sets up a sample HTA system and starts the move to hold at a value of 25.

Description:

The

HTACHANNEL keyword specifies the analog channel to monitor during a Hold To Analog move on

that axis. The analog channel can be in any configuration (

ADCMODE) as long as it is not turned off the

analog channel can have any configuration. The channel number must be a valid channel number.

Reading the

HTACHANNEL keyword returns the analog channel currently being used.

Example:

HTACHANNEL.6 = 7

Use analog channel 7 for a HTA move on axis 6.

The default channel assignments are as follows:

Axis 0 1 2 3 4 5 6 7

Analog Channel 0 1 2 3 4 5 6 7
