Animation movements come in two basic flavors: 1) Analog, and 2) Digital. Although

we are used to thinking of everything ‘digital’ being superior to anything analog (like

digital CDs vs. analog LP records), this is the one case where it just ain’t so

. Analog

movements are used in almost all high-end animated figures. They give you a fluid,

lifelike motion that digitals just can’t do.

A typical digital animation movement is at either one end of its travel or the other, or moving between these two positions 2 . The speed of the action is set by the flow controls that control how fast the air (or oil) can get into and out of the cylinder. An analog control is like the light dimmer on the wall of your dining room.

When using a potentiometer, this can add from $25 (for a rotary pot) to $100 or more (for a linear pot or LVDT). Electronic FeedBack cards typically use what is called a ‘PID’ loop to control the position of a movement. This type of loop is available on our new four channel PID-Quad and BS-EFB Electronic FeedBack cards.

This adds a second ‘force’ feedback to an analog movement. This is usually a strain gauge or accelerometer mounted on the cylinder in addition to the normal position sensor. This measures the force being applied by the cylinder and feeds this to the FeedBack card.

Installation: Connections for channel 0 output shown. All other channels are identical.

A number of different styles of position transducers are available. These include standard linear and rotary potentiometers as well as 'string pots' in which a small steel cable extends to measure distances.

This typically comes from a BS-ANA or other analog output control system. It is fed to the feedback card through the ten position ribbon cable connector.

These are: 1) Proportional (‘P’) or Gain: This controls how much the valve will be opened for a given distance between the commanded and actual positions of a movement.

Most valves have some sort of setscrews or other mechanical adjustments which will allow you to center the valve until there is no movement in the cylinder. If you can’t disconnect the valve from the feedback card, you can attach a voltmeter across the valve outputs and position the movement until it stays at mid-stroke.
