Setting up Compax3 C3I22T11

4.1.11. I/O Assignment
For intra-device inputs I0 .. I3 as well as the outputs O0 ... O3 you can choose
between fixed or free assignment (see below).
Control via DeviceNet does not require an M option (M10 / M12).
If an M option is available, 12 inputs/outputs (ports) are freely assignable. These
can be configured as inputs or outputs by groups of four and be activated resp.
read via Object 121.2 and Object 133.3.
The signal inputs I4 ... I7 are fixedly assigned
If the respective functions are not needed, these inputs can also be used for con-
trol.
I5 and I6 can, for example, be used as free inputs if the limit switch function is
deactivated.
Assignment of the intra-device inputs and outputs
PIN
X12
Input/output High density/Sub D
1 A +24VDC output (max. 400mA)
2 O0 No Error
3 O1
Position / speed / gear synchronization
attained (max. 100mA)
4 O2
No power output stage current (max.
100mA)
5 O3
Axis stationary with current, with set-
point 0 (max. 100mA)
6 I0="1": Quit (positive edge) / Energize the axis
The address of the current motion set
is read in new.
I0="0" Deenergize axis with delay
7 I1 No stop
8 I2 JOG +
9 I3 JOG -
Only for "fixed as-
signment"
Functions are availa-
ble, if "Fixed as-
signment" was selec-
ted for the I/O as-
signment in the confi-
guration wizard
10 I4 Reg input
11 E 24V input for the digital outputs Pins 2 to 5
12 I5 Limit switch 1
13 I6 Limit switch 2
14 I7 Machine reference initiator
15 A Gnd 24 V
All inputs and outputs have 24V level.
Maximum capacitive loading of the outputs: 30nF (max. 2 Compax3 inputs can be
connected)
Input-/Output extension (see page 389)
The display o
f the digital inputs in the optimization window of the C3 ServoManager
does not correspond to the physical status (24Volt=on, 0Volt=off) but to the logic
status: If the function of an input or output is inverted (e.g. limit switch, negatively
switching), the corresponding display (LED symbol in the optimization window) is
OFF with 24Volts at the input and ON with 0 Volts at the input.
