Analog Motor Controller

This driver can be used with stages that allow position control via an analog control voltage in the range -10V to 10V.

Hardware Configuration

Connect a BNC cable between a free DAQ analog output and the motor controller signal inputs.

Software Config

Note

One Analog Motor Controller device is configured per actuated dimension of the stage. If you have 3 dimensions for your stage, you will configure 3 such Analog Motor Controller devices.

In ScanImage, open the Resource configuration window from the startup dialog or from the Main Controls window under File>Configuration.

1. From the Resource Configuration window, click the “+” button. Select Motor Controller from the sidebar, and select Legacy Motor. Give it a name describing the dimension that it actuates and click continue.

2. A window like shown below will be displayed. Below the image is a description of each of the configuration parameters

Minimum Position [um]	The end of travel position associated with the most negative command voltage
Maximum Position [um]	The end of travel position associated with the most positive command voltage
Position Device	The analog output DAQ/port used to command the position
Command Scaling Factor [V/um]	The scaling factor to apply to AO signal to convert to position using linear interpolation
Command Volts Offset [V]	The offset to apply to the AO signal to convert to position using linear interpolation
Settling Time [s]	The duration after a move command is initiated to wait before a new move command can be initiated.

Once the device has been configured, it can be added to the ScanImage® imaging system via the left pane of the Resource Configuration window under the ScanImage tab after clicking the SI Motors button. This will reveal a page (see below) that will allow each of the axes to be configured as Analog Motor Controller devices.

Scaling factors are provided in addition to the configuration settings.
