K-Cube Piezo Driver
3.3.4 Connecting to a Power Supply
1) Using the front panel connector as shown above, connect the unit to a regulated
DC power supply of the rating detailed in Section 3.3.
2) Switch on the Power Supply unit, then switch on the KPZ101.
3) The Version number of the embedded software is displayed for a few seconds.
Thorlabs offers a com pact, two-way power supply unit (TPS002), allowing up to two
piezo driver K-Cu bes to b e powered from a single mains outlet. However, if an
external supply is to be used, see Appendix A.1 for power supply connector pin out
details.
3.3.5 Powering Down The Unit
Warning
The unit must be connected only to a DC supply as detailed in Section 3.3.
Connection to a supply of a different rating may cause damage to the unit and
could result in injury to the operator.
Caution
Ensure the power switch on the front panel of the unit is switched off
before connecting power to the K-Cube. Always power up the K-Cube unit
by its ON switch. DO NOT connect the K-Cube unit to a 'live' external
power supply. Doing so (i.e. “hot plugging”) carries the risk of
PERMANENT damage to the unit. Similarly, to power down the unit, turn
the power switch off before disconnecting the power supply.
Caution
If an external power supply is used, ensure that the 3 supply voltages are
turned on and off simultaneously. Applying the supply voltages with a
large (more than 1 second) time delay between them can result in the
piezo cube showing an incorrect reading.
Warning
The controller may cause drive voltage spikes on power down. In applications
requiring the highest sensitivity, the piezo drive voltage should be set to zero,
and the HV cable disconnected before the unit is powered down.
Always be use the front panel ON switch to power down the unit. When in the
ON position, the unit is fully powered up. When the switch is turned to the
Standby position, the unit initiates a controlled power down sequence, saving
all user-adjustable parameters to non-volatile memory before turning off the
power. For the first few seconds, the shutdown can be cancelled by turning the
switch on again, in which case the unit will save the parameters but will remain
powered up. In a powered down (Standby) state, the logic circuits are powered
off and the unit will draw only a small quiescent current.
