Stage Axis Settings
These parameters are read automatically when the actuator/stage was associated at
start up - see Section 3.5. These settings are provided for information only and cannot
be adjusted. They should always be quoted when requesting technical support.
Actuator Name - The name (part number) of the stage or actuator connected.
Serial Number - The serial number of the stage or actuator connected.
Stage ID - The ID number of the stage or actuator connected. This nuber is used by
the server to assign stage specific parameter values at start up.
Counts per mm - The number of encoder counts per millimeter of travel of the DC
servo motor (minimum '1', maximum '10,000').
Homing Settings
For DDSM100 users. The Homing, Limit Switch and Motor parameters
described on the next two pages are not applicable for the DDSM100
stages because the stage does not use a limit switch as a reference point
for homing. Instead, it uses a special reference marker pulse from the
encoder. Homing on these stages involves a search for this reference
marker. Initially, the stage moves in the forward direction and if the
reference marker is found before the stage hits the forward limit switch,
then homing is completed. If not, the stage reverses direction and
continues to search for the reference marker. Due to the different method
used, only the Homing Velocity parameter can be adjusted, although
normally the default value is suitable for nearly all applications. All other
When homing, a stage typically moves in the reverse direction, (i.e. towards the
reverse limit switch). The following settings allow support for stages with both Forward
and Reverse limits.
Typically, the following two parameters are set the same, i.e. both
Direction - the direction sense that the motor moves when homing, either Clockwise
or Counter Clockwise.
Limit Switch - The hardware limit switch associated with the home position, either
Ignore, Clockwise or Counter Clockwise.
Zero Offset - the distance offset (in mm or degrees) from the limit switch to the Home
position.
Velocity - the maximum velocity at which the motors move when Homing.
