Setting up Compax3 C3I22T11140 192-120114 N5 C3I22T11 June 20084.1.11. I/O Assignment For intra-device inputs I0 .. I3 as well as the outputs O0 ... O3 you can choosebetween 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. Thesecan 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 assignedIf 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 isdeactivated.Assignment of the intra-device inputs and outputsPINX12Input/output High density/Sub D1 A +24VDC output (max. 400mA)2 O0 No Error3 O1 Position / speed / gear synchronizationattained (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 axisThe address of the current motion setis read in new.I0="0" Deenergize axis with delay7 I1 No stop8 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 wizard10 I4 Reg input11 E 24V input for the digital outputs Pins 2 to 512 I5 Limit switch 113 I6 Limit switch 214 I7 Machine reference initiator15 A Gnd 24 VAll inputs and outputs have 24V level.Maximum capacitive loading of the outputs: 30nF (max. 2 Compax3 inputs can beconnected)Input-/Output extension (see page 389)The display of the digital inputs in the optimization window of the C3 ServoManagerdoes not correspond to the physical status (24Volt=on, 0Volt=off) but to the logicstatus: If the function of an input or output is inverted (e.g. limit switch, negativelyswitching), the corresponding display (LED symbol in the optimization window) isOFF with 24Volts at the input and ON with 0 Volts at the input.Optimization win-dow display
