Connect/Disconnect Function Of Sscnet Communication - Mitsubishi Electric RD77MS2 User Manual

9.12
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.
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.
Precautions during control
• 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.
• 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.
• 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".
• 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.
• Execute the connect/disconnect command to the A-axis for multiple-axis servo amplifier.
• When using the driver communication function, it can be disconnected by executing the connect/disconnect command,
however it cannot be connected again.
• The connect/disconnect/execute command cannot be accepted during amplifier-less operation mode. "[Md.53] SSCNET
control status" will be "0: Command accept waiting" (The disconnection is released.). If being switched to the amplifier-less
operation mode when "[Md.53] SSCNET control status" is "1: Disconnected axis existing", the disconnected axis is
automatically connected when switching to the normal operation mode again. If being switched to the amplifier-less
operation mode when "[Md.53] SSCNET control status" is "-1: Execute waiting", the connect/disconnect command
becomes invalid.
