PIA Series Inertial Piezo Motor Actuators
3.1.3 Fitting to a Barrel Mount
1) Set the required actuator cable exit position - see Section 3.1.2.
2) Remove the barrel locking ring from the actuator.
3) Loosen the pinch bolt in the actuator clamp.
4) Fit the actuator into the clamp, ensuring that the mounting barrel is fully located in
the clamp and reference surface is located flush against the clamp housing.
5) Rotate the actuator to orientate the housing as required.
6) Tighten the pinch bolt. Take care not to apply excessive clamping forces by
overtightening. Tighten until the actuator is just held, then tighten by another 1/8
to 1/4 turn as necessary. Do not overtighten the pinch bolt.
7) Readjust the cable exit position as required.
Fig. 3.2 Fitting a PIA25 to a LNR25 Stage
Caution
Only fit an actuator with the same travel as the stage. Fitting actuators
with a longer travel will cause excessive axial preload. Do not exceed the
preload values specified in Chapter 5.
Caution
During item (6), excessive clamping force onto the brass barrel mount
may result in damage to the drive screw and reduced stepping
performance.
