start up. Refer to the handbook for the associated controller for more information
on driving the actuator/stage.
Note
These stepper motor drives have no forward limit switch and the travel is limited
dependent on the axis to which it is attached. When the DRV208 motors are used
with our Nanomax series stages, suitable defaults are loaded at start up to prevent
the motor being overdriven. If the axis is driven towards the reverse limit switch, at
a certain position the platform stops moving while the drive itself continues to move
until the limit switch is reached. The drive must then be moved positively by a certain
distance before the platform begins to move. This distance is just less than the
offset.
When fitted to other stages or third party optomech products, it is possible that the
motor will reach the mechanical hardstops of the stage before the travel limits of the
actuator. In this case, consideration should be given to creating custom travel limit
settings - see the handbook for the associated motor controller for more information.
When creating a program to control the actuator, it is recommended to avoid running
into the mechanical hard stops.
