As shown in Figs. 4.3 and 4.4 above, the external input signals are non-voltage
contact inputs or open collector inputs. Some of the system inputs (STOP, CYCLE,
LOW_SPD, BREAK, SVOFF) are normal close contact inputs, and the others are
normal open contact inputs.
For the function, circuit to use, changeover of common wire, etc., see Para. 4.8.2.
4.8.2 Digital Input Signal
Designation Digital input signal
DI_1 ~ DI_8, system input signals
Connector input
terminal Digital input signals are assigned to INPUT-1 ~ 4 pins and 20
~ 23 pins.
The system input signals are assigned to INPUT-7 ~ 10 pins,
12~14 pins, 25~28 pins and 31~32 pins.
Common wires for DI_1 to DI_8 are INCOM, and common
wires for system input signal are SYSINCOM.
For details of the connection, see the figure below (i.e.,
example of circuit).
Function Each signal status of DI_1 ~ DI_8 can be identified by the
robot program (DIN command) to branch the processing of
program. Also, it is possible to perform interruptive
processing of each signal (DI_1 ~ DI_8) with change in signal
status monitored during the robot operation.
Input type Non-voltage contact input or transistor open collector input.
