6.27 Servo amplifier general input/output
6.27.1 Summary
The servo amplifier general input/output function is a function that controls the input/output signal connected to
the servo amplifier via SSCNET. The user program can control the input/output signal with the digital
input/output table, by assigning the servo amplifier general input/output signal to the digital input/output table.
The points of the input/output signal differ depending on the servo amplifier model.

The points of the input/output signal differ depending on the servo amplifier model.
POINT
When a communication error (system error E401 to E407) occurs or SSCNET
is disconnected, all the general input/output signals of the servo amplifier turn
off.
off.
The general input signal of the servo amplifier shares the connector pin with
the sensor signal (LSP, LSN, DOG). Therefore, the sensor signal cannot be
input if general input signal of the servo amplifier is used as other than the
sensor signal. In this case, set the sensor input option (parameter No.0219)
to "2: Digital input" and assign a digital input signal as a sensor signal in the
sensor signal connection specification (parameter No.021A to 021C). The
sensor signal can be controlled by a command from the user program (writing
of the dual port memory) when the sensor input method (parameter No.0219)
is set to "4: Dual port memory".

The delay time from an input of the general input/output signal of the servo
amplifier to the update of the digital input table is "approx. 0.88ms (control
cycle 2)" (approx. 2.7ms when the control cycle is 0.88ms).

The delay time from the update of the digital output table by the user program
to the output of the general output signal of the servo amplifier is "approx.
0.88ms (control cycle 3)" (approx. 3.5ms when the control cycle is
0.88ms).
In the case of the digital output signal using in the other axes start function,
the delay time from other axes start condition satisfaction to the output is
"approx. 0.88ms (control cycle 2)" (approx. 2.7ms when the control cycle
is 0.88ms).
