adapter module connection. (This is the
sole location for an FDPI-02 diagnostics
and panel interface.)
SLOT 1
I/O extension, encoder interface or fieldbus
adapter module connection
SLOT 2
I/O extension, encoder interface, fieldbus
adapter or FSO-xx safety functions module
connection
SLOT 3
RDCO-0x DDCS communication option
module connection
SLOT 4
Memory unit connection
X205
Holder for real-time clock battery (BR2032)
BATTERY
Mode selector for analog input AI1 (I =
current, U = voltage)
AI1
Mode selector for analog input AI2 (I =
current, U = voltage)
AI2
Termination switch for drive-to-drive link
(D2D)
D2D TERM
Ground selection. Determines whether
DICOM is separated from DIOGND (ie. the
common reference for the digital inputs
floats). See the ground isolation diagram.
DICOM=
DIOGND
7-segment display
Multicharacter indications are displayed as repeated se-
quences of characters
(“U” is indicated briefly before “o”.)
Control program running
Control program startup in progress
(Flashing) Firmware cannot be started.
Memory unit missing or corrupted
Firmware download from PC to control unit
in progress
At power-up, the display may show short
indications of eg. “1”, “2”, “b” or “U”. These
are normal indications immediately after
power-up. If the display ends up showing
any other value than those described, it in-
dicates a hardware failure.
