This function is used to temporarily suspend SSCNET communication while servo
amplifiers and/or SSCNET cables after Axis 1 are exchanged with the power supply
ON in a Multiple CPU system.
SD803 is required for connect/disconnect and SD508 stores the command status for
"accept waiting" or "execute waiting" during this process. If a servo amplifier was
previously removed using the connect/disconnect function, it must be used again to
reconnect the servo amplifier. This function is only required when there is a desire to
maintain communication to all axes in front of the one being removed.
No connect/disconnect processing is required if the power supply to Axis 1 is
shutdown.
