Operation
4.1 Introduction
Caution
. The PRM1-Z7 series stages form part of the Thorlabs Nanopositioning
system. We recommend they are driven by the Thorlabs TDC001 T-Cube DC Servo
Motor Driver. If the stage is being driven by any other driver or controller, consult the
Section A.1. for motor pin out details.
The stages are connected to the controller via a flying lead terminated in a D-type
connector.
Warning
. The controller must be switched OFF before the stages are plugged in or
unplugged. Failure to switch the controller off may result in damage to either the
controller, the stage, or both.
4.2 Associating the Stage Type
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 and axis with the motor controller. Once this
association has been made, the APT server applies automatically, suitable default
parameter values on boot up of the software.
Caution
.
• By default, the software associates a Z706 type actuator, unless the user has used the
APTConfig utility to associate a particular stage.
• When the PRM1-Z7 stage is associated with the driver, default settings applicable to the
PRM1-Z7 will be loaded. These settings are incompatible with linear type stages and
actuators (e.g. MST25X, Z706). Before the TDC001 unit can be used to drive a stage
other than the PRM1-Z7, it must be associated with the new stage type. If this is not done,
damage could be caused to the motor limit switches.
