for more details.
CH-A and CH-B - (SMA Connectors) Analog input, u
sed to control the velocity of the
piezo actuator from an external source. This input allows an external signal to drive the
output to its full scale velocity in either direction. The voltages to be applied are different
depending on the particular hardware unit being driven.
On legacy Rev 1 hardware units, a 0V input gives max velocity in the reverse
direction, whereas 10V input gives max velocity forwards; a 5V input results in no
movement. Rev 1 units running the latest firmware v10002 can be identified by an
asterisk after the firmware revision number on start up - see Fig. 3.4.
On later Rev 2 hardware units, a -10V input gives max velocity in the reverse direction,
whereas +10V input gives max velocity forwards; a 0V input results in no movement.
See
Section 4.5.
for information on how to enable control via these analog inputs.
The channels controlled by these inputs is dependent upon the ‘Axis Mode’ setting - see
Section 4.4.8.
and
Section 6.3. for more details on this mode.
MOT Terminals - (SMC Connectors) The unit is supplied with four SMC O/P
connectors as shown above, which is compatible with all Thorlabs inertial piezo motor
driven positioning stages and actuators.
Caution
The PIA series piezo inertia actuators are shipped with 1.1 m (3.3’) of cable.
Thorlabs offer 1.5m extension cables (PAA101) and male adapters (T5026) to
extend the drive cable length to 2.5m, see www.thorlabs.com.
Due to the capacitance of the cables, do not use cables longer than 2.5 m in
total.
