Connect/Disconnect Function Of Sscnet Communication - Mitsubishi Electric Q Series Programming Manual

4 AUXILIARY AND APPLIED FUNCTIONS

4.11.1 Connect/disconnect function of SSCNET communication

Temporarily connect/disconnect of SSCNET communication is executed during
Multiple CPU system's power supply ON.
This function is used to exchange the servo amplifiers or SSCNET cables.
Set the request for the connect/disconnect of SSCNET communication in SSCNET
control command (SD803), and the status for the command accept waiting or execute
waiting is stored in SSCNET control status (SD508).
Use this device to connect the servo amplifiers disconnected by this function.
When the power supply module of head axis of each SSCNET line (servo amplifier
connected directly to the Motion CPU module) turns OFF/ON, this function is not
necessary.
POINT
(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 SSCNET control status device (SD508) only changes into the execute
waiting status (-1) even if the disconnect command of SSCNET
communication (1 to 32) or connect command of SSCNET communication
(-10) is set in SSCNET control command device (SD803). The actual
processing is not executed. Set the execute command (-2) in SSCNET control
command device (SD803) to execute.
(3) When the disconnect command of SSCNET communication (1 to 32) is set to
axis not disconnect, the SSCNET control status device (SD508) returns the
command accept waiting status (0) without entering the execute waiting status
(-1).
(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.
(5) When the connect/disconnect command is executed to the axis allocated to B-
axis and C- axis of MR-J4W- B or B- axis of MR-J3W- B, it can be
disconnected, however it cannot be reconnected. Execute the
connect/disconnect command to the A-axis.
(6) Only the release command of amplifier-less operation can be accepted
during amplifier-less operation. The connect/disconnect command cannot be
accepted.
