Alm (Servo Alarm) Signal - YASKAWA SGD7S-****20A Series Product Manual

6.1 I/O Signal Allocations

6.1.3 ALM (Servo Alarm) Signal

Forcing Outputs with MECHATROLINK-III Commands
You can use the servo command I/O signal (SVCMD_IO) command through MECHATROLINK-
III communications to force outputs on general-purpose sequence output 1 (SO1) to general-
purpose sequence output 3 (SO3).
Use Pn56A = n.XXX to set the output signal reference method for SO1 to SO3.
Refer to the following manual for detailed information on the servo command I/O signal (SVCM-
D_IO) command.

and signal set by SVCMD_IO.
If you change the setting of Pn56A from the default setting to n.1, an OR of the /BK
signal and the signal that is set with the servo command I/O signal (SVCMD_IO) command
will be output.
To output only the signal that is set with the servo command I/O signal (SVCMD_IO) command on
SO1 to SO3, disable the signal that is allocated with the parameter (i.e., set it to not use the sig-
nal).
Configure an external circuit so that this alarm output turns OFF the main circuit power supply to
the SERVOPACK whenever an error occurs.
