TTroubleshooting

Incorrect control mode of the piezo channel

⇒ Check the current control mode using the ONL? command or on the

main screen of the E-517 display. The current control mode of a piezo

channel determines the applicable control sources for the output voltage

and hence for the axis motion. See

"Control Modes" (p. 23) for details.

Incorrect configuration

⇒ Check the parameter settings on the E-517 with the SPA? and SEP?

commands.

Incorrect GCS syntax version

⇒ Check the current GCS syntax version using the CSV? command or on

the main screen of the E-517 display ("E517" or "E516", in the top right

corner of the display). The current GCS syntax version determines the

applicable GCS commands and software tools (except for the PITerminal,

the software on the E-517 CD can not be used when the E-517 is switched

to the E-516 GCS syntax version). See

"Select Command Set Version"

(p.

41) for details.

The high voltage output of the piezo control electronics is

deactivated, while the communication with the E-517 is still

possible

⇒ The high voltage output of the piezo control electronics may be

deactivated automatically when an internal temperature sensor detects

overheating. To reactivate the high voltage output, let the device cool down

and power-cycle or reboot the E-517.

Note that the wave generator output will continue even if the high voltage

output is deactivated, i.e. if a certain number of output cycles was set, they

may have already finished when the high voltage output is reactivated.

How to avoid overheating:

Keep the ambient temperature at a noncritical value: Note that the

difference between ambient temperature and internal temperature of the

piezo control electronics normally is about 20 Centigrade (36 Fahrenheit)

degrees.

Place the system in a location with adequate ventilation. Allow at least

10 cm (4 inches) clearance from the top and the rear of the unit and 5 cm

(2 inches) from each side. If this is not possible, keep the ambient

temperature low. Never cover the ventilation openings of the piezo control

electronics as this will impede ventilation.
