PZ166E
E-625 Piezo Servo Controller
Problem
Possible causes
Solution
Wrong axis
commanded
Make sure that the correct axis identifier is used and
that the commanded axis belongs to the correct
positioner.
An axis identifier is even required on systems with only
one axis.
Incorrect
configuration
Use the
SPA?
command to check the E-816
computer interface submodule parameter settings.
Voltage output of
the E-625 is
deactivated
When the internal temperature reaches
≥75°
C, the
voltage output of the E-625 is deactivated and the
positioner stops moving. When the internal temperature
then drops to <60° C the voltage output is switched on
again automatically.
Ensure sufficient ventilation at the place of
installation (p. 15).
When using the wave table output, reduce the
frequency and/or the amplitude and/or the output
duration.
Communica-
tion with the
controller fails
The wrong
communication
cable is used or it is
defective
Check the cable.
The RS-232 connection requires a null modem cable.
Check whether the cable works on a fault-free
system.
Communication
interface is not
configured
correctly
When using the RS-232 interface:
Check the port settings and the baud rate (can be set
with the
BDR
command). The serial port on the E-816
computer interface submodule is set as follows:
−
115200 baud
−
8 data bits
−
1 stop bit
−
No parity
−
RTS/CTS
Use a PC with a "genuine" RS-232 interface.
Using an USB-to-RS-232 adapter can result in data loss
during communication, especially when larger amounts of
data are transmitted.
When using the USB interface:
Once the E-625 has been switched on, a message will
appear that new hardware has been detected.
Install the USB driver from the PI software CD. The
installation files for the USB drivers can be found in
the \SingleSetups folder on the CD.
