4.2.4 SVON and RDY
All 864 axes are equipped with SVON and RDY signals, which are
general purpose output and input channels, respectively. The
SVON is used to interact with the servomotor drivers as a Servo
ON command, and RDY to receive the Servo Ready signal. There
are no built-in procedures for SVON and RDY.
The SVON signal is controlled by the software function
_8164_Set_Servo().
RDY pins are dedicated for digital input usage. The status of this
signal can be monitored using the software function
_8164_get_io_status().
