Operational Overview
Digital Input Setup for Analog Position Mode
Analog Position Mode Enable
• Move Motor from Starting “Position Command” to “Analog Position Command”
Note: if the two values are equal no motion is expected
• Motion is limited by “Accel Limit Starting”
Define Analog Position
• Set “Position Command” equal to “Analog Position Cmd”
• Note: No motion is executed
• Note: “Enable Analog Position” must be disabled.
• Note: This basically redefines the home.
Teach Analog Position
• Pulsed twice. First pulse sets the Min values second pulse sets the Max values.
• The teach Function is user definable. The teach navigation tree icon indicates what will be executed during the Min
pulse and what will be executed in the Max pulse.
Example: Setting up Analog Positioner with Teach Mode
Step 1:
1. On the Setup view, select the operating mode “Analog Position Mode” to display analog positioner settings.
2. Enable and type in the “Velocity Limit Starting” value to define a safe velocity to get into the initial analog
position on enabling analog position.
3. Type in the “End of Home Position” value to reset the position to a known value. Zero is a good value for this
example.
4. Type in the “Analog Deadband” to reduce flutter. Zero is a good value for this example.
5. If desired, enable and define the Following Error Limit parameter. Have it disabled for this example.
Step 2:
1. On the Setup view, select the operating mode “Velocity Mode” to display Velocity Mode Setup tab.
2. Select the Velocity Sub-Mode of Preset Velocity
3. Define Preset 0 and 1 as zero velocity, Preset 2 as 50 rpm and Preset 3 as -50.
We will set two input lines to presets, one line will select direction (-50 or +50) while the other enables or
disables (selects 0 velocity or one of the presets)
