14.12 Connect/disconnect function of SSCNET communication
Temporarily connect/disconnect of SSCNET communication is executed during
system's power supply ON.
This function is used to exchange the servo amplifiers or SSCNET cables.
The details shown below explain about the "Connect/disconnect function of SSCNET
communication".

[4] Procedure to connect/disconnect
[5] Program
[1] Control details
Set the request for the connect/disconnect of SSCNET communication in
"
Cd.102
SSCNET control command
", and the status for the command accept
waiting or execute waiting is stored in "
Md.53
SSCNET control status
".
Use this buffer memory to connect the servo amplifiers disconnected by this
function.
When the power supply module of head axis of SSCNET system (servo amplifier
connected directly to the QD77MS) turns OFF/ON, this function is not necessary.
[2] Precautions during control
(1) Confirm the LED display of the servo amplifier for "AA" after completion of
SSCNET communication disconnect processing. And then, turn OFF the
servo amplifier's power supply.
(2) The "
Md.53
SSCNET control status
" only changes into the "-1: Execute waiting"
even if the "Axis No.: Disconnect command of SSCNET communication" or
"-10: Connect command of SSCNET communication" is set in "
Cd.102
SSCNET control command
". The actual processing is not executed. Set "-2:
Execute command" in "
Cd.102
SSCNET control command
" to execute.
(3) When the "Axis No.: Disconnect command of SSCNET communication" is set
to axis not connect or virtual servo amplifier, the status will not change without
"
Md.53
SSCNET control status
" becoming "-1: Execute waiting".
(4) Operation failure may occur in some axes if the servo amplifier's power
supply is turned OFF without using the disconnect function. Be sure to turn
OFF the servo amplifier's power supply by the disconnect function.
