Labeling Type Function
Ch1/2 Servo
Ch3/4 Servo
LED
green
Servo mode indicator for the axes:
 Continuously lit: Servo mode is on (closed-loop
operation) for at least one of the axes
 Continuously off: Servo mode is off (open-loop
operation) for the axes
 Flashing: E-727 initializes parameters and – if the OFL
LEDs are flashing in addition - searches for a DHCP
server during power-on or reboot sequence
The servo mode of the individual axes can be queried with
the SVO? command.
USB-B socket Universal serial bus for connection to the PC
SPI
Display port
Connection to SPI (serial peripheral interface) master. Can
be used for transferring position data from and to the E-727
with minimum latency and update rates as high as the servo
update rate of the E-727. It is also possible to send and
receive ASCII data so that the connected master has full
access to the PI General Command Set (GCS). See “SPI-
Interface” (p.
144) for details.

Socket for piezo stages; carries the voltage for the piezo
actuators (-30 to 130 V) and the signals of the sensors in the
mechanics.

can be used to monitor the position of an axis or for
controlling an external amplifier
