Expansion card -I/O-14/08-
This chapter describes the I/O-expansion card -I/O-14/08-. It only describes the additional features
that the expansion card makes available for the AX2000.
The -I/O-14/08- provides you with 14 additional digital inputs and 8 digital outputs. The functions of
the inputs and outputs are fixed. They are used to initiate the motion tasks that are stored in the
servo amplifier and to evaluate signals from the integrated position control in the higher-level
control.
The functions of the inputs and signal outputs correspond exactly to the functions that can be
assigned to the digital-I/O on connector X3 of the AX2000.
The 24VDC supply for the expansion card is taken from the controller. All inputs and outputs are
electrically isolated from the servo amplifier by optocoupler.

Light emitting diodes (LEDs)
Two LEDs are mounted next to the terminals on the expansion card. The green LED signals that
the 24V auxiliary supply is available for the expansion card. The red LED signals faults in the out-
puts from the expansion card (overload, short-circuit).

The 24VDC voltage has to be supplied by an electri-
cally isolated power supply, e.g. with insulating
transformer.
