14.13 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".
[1] Control details
[2] Precautions during control
[3] Buffer memory list
[4] Procedure to connect/disconnect
[5] Program
[1] Control details
Set the connect/disconnect request 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 Simple Motion module) 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.
