Chapter 3 Operation

3.1 Manual Differential Drives and Differential Micrometer Drives

3.1.1 Adjusting Micrometer Drives
Turn the coa rse adjustment clockwise until the platform of th e NanoMax begins to
move. By use of the fine adjustment, sub-micron resolution is now achievable.
3.1.2 Reading Micrometer Drives
3.2 Stepper Motor Drives
To ensure that a particular stage is driven properly by the system, a number of parameters
must first be set. These parameters relate to the physical characteristics of the stage being
driven (e.g. min and max positions, leadscrew pitch, homing direction etc.).
To assist in setting these parameters correctly, it is possible, using the APT Config utility,
to associate a specific stage type a nd axis with the motor controller channel. Once this
association has been made , the APT server
parameter values on boot up of the software.
To ensure corr ect operation, it is important to select th e correct stage type fo r your
controller. If us ing a BSC20x ser ies controller, select the appropr iate 'HS NanoMax'
option. If using a legacy BSC0xx or BSC10x controller, choose an option without the 'HS'
prefix.
1) Shut down all applications using the APT server (e.g. APT User or your own
custom application).
