E-727 for Capacitive Sensors: Socket for Piezo Stages
„-30 to +130 V“ – D-Sub special 25W3 (f)
Pin
Signal
Function
With E-727.3CDA and .3CDAx models:
The Piezo Ch 4 lines of the socket for
piezo stages share output signal
channel 4 of the E-727 with analog
output 1 (pin 8 on the
Analog I/O
socket). The use of output signal
channel 4 can be configured via the
value of the
Select Output Type
parameter (ID 0x0A000003) as
follows:
1: Output voltage for a piezo
actuator in the stage, output as
Piezo Ch 4 (pins 7 and 18)
2: Position monitor of an axis. The
value of the
Select Output Index
parameter (ID 0x0A000004)
determines the axis whose
position is to be output. Output
on pin 8 of the
Analog I/O
socket
(p. 228).
5: Control signal for an external
amplifier. The value of the
Select
Output Index
parameter (ID
0x0A000004) determines the
output signal channel whose
control value is to be output.
Output on pin 8 of the
Analog I/O
socket.
If a total of four piezo actuators are
present in the stage(s), output signal
channel 4 must always be configured
for use as output voltage (Piezo Ch 4).
Note that PI will supply E-727 and the
piezo stage(s) as a system with
appropriate settings. If you are not
sure whether your system can be
configured for output of position
monitor or control signal, contact our
customer service department
(p. 234).
