Selecting the Servo Mode
The closed-loop operation uses the E-802.55 servo controller submodule that is installed in the
E-625. The use of the E-802 servo controller submodule is set (p. 38) with an on-board jumper.
In the default position, the E-802 servo controller submodule is active and the servo mode can
be set as follows:
Settings of the DIP switch block (E-625.CR and E-625.C0)

SVO Command (E-625.CR only)
INFORMATION
To be able to set the servo mode over the E-816 computer interface submodule with the SVO
command, the DIP switch 3 must be set to open-loop operation (up).
Send the corresponding axis-specific SVO command via the communication interface or
by using a macro running on the E-816 computer interface submodule.
The
SVO?
command can be used to get the last sent SVO settings for each axis.
SVO?

show the settings of the DIP switch 3 for the servo mode.
Closed-loop operation can also be activated by a startup macro (refer to the user manual for
the E-816 computer interface submodule).
