Analog inputs (pins 9, 2, 10, 3, 11, 4, 12, 5):
 Input impedance: 150 kohm
 Max. input voltage (single ended): ±14 V
 Resolution ADC: 18 bit
 E-727.3CDA, .3CDAx: Via the value of the Sensor Range Factor parameter (ID
0x02000100), the analog input lines 1 to 4 (accessible as input signal channels 4 to 7)
can be configured as follows:
− 1: Input range ±5 V
− 2: Input range ±10 V
 E-727.3RDA, .3RDAx, .3SDA, .3SDAx: Via the value of the Sensor Range Factor
parameter (ID 0x02000100), the analog input lines can be configured as follows:
− Analog input line 1 (accessible as input signal channel 4):
 1: No input possible on pins 2 and 9 of Analog I/O; input signal channel 4 is
used for a piezoresistive or strain gauge sensor (input via pins 6, 24, 25 of
the socket for the piezo stage(s) (p. 226)
 2: No input possible on pins 2 and 9 of Analog I/O; input signal channel 4 is
used for a PT1000 temperature sensor (input via pins 1, 20 of the socket for
the piezo stage(s))
 3: Input range ±5 V
 4: Input range ±10 V
− Analog input lines 2 to 4 (accessible as input signal channels 5 to 7):
 1: Input range ±5 V
 2: Input range ±10 V
Analog outputs (pins 8, 14, 7, 15):
 Min. ±10 V at 5 mA output current
 Resolution DAC: 20 bit
 Sensor Monitor lines 1, 2, 3 (pins 14, 7, 15): The (raw) signals of the sensors 1, 2 and
3 which are fed into the E-727 on the socket for the piezo stage(s) (p. 225 or p. 226)
are looped through to these lines. The Sensor Monitor lines are not available as
output signal channels in the firmware of the E-727 and not accessible for
commands.
 Analog Out 1 (pin 8; accessible as output signal channel 4) can be configured using
the value of the Select Output Type parameter (ID 0x0A000003) as follows:
− 1: Output has no meaning; output signal channel 4 is used as output voltage for
a piezo actuator in the stage, output as Piezo Ch 4 on the socket for piezo stages
(p. 225 or p. 226).
− 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.
− 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.
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).
