6.26 Digital input/output
6.26.1 Summary
The digital input/output function is a function that controls the general input/output signal of the servo amplifier
assigned to the digital input/output table. The user program can check whether the digital input/output signals
are on/off by using the digital input/output table. The points for the each input/output signal can be assigned up
to 1024.
CAUTION
If the digital output signal is updated from the user program during controlling of the digital
output signal by the other axes start function, the consistency of the data may not be kept. This
condition is applied to the case when the host controller and position board update the data at
the same time to the same digital output area number. In this case, read/write the digital output
signal after controlling the possessory right of the digital output signal using the exclusive control
function.
POINT
For detailed specifications and how to assign the input/output signal to the
digital input/output table, refer to Section 6.27.
