4 AUXILIARY AND APPLIED FUNCTIONS
4.11 Connect/Disconnect Function
This function is used to connect/disconnect the SSCNET communication temporarily,
when the servo amplifier or SSCNET
cable on the SSCNET system are exchanged
during the power supply ON of Motion CPU. An user side requires connect/disconnect
to a system, and a system side stores the states of command accept waiting or
execute waiting for connect/disconnect. Moreover, also use this device to re-connect
the servo amplifier shut off by the connect/disconnect device. When the power supply
for axis 1 is turned OFF/ON on the SSCNET system, a connect/disconnect processing
is unnecessary.
(1) Setting value/monitor value of connect/disconnect device are shown below
Device No.
Setting value/
monitor value
Overview
Setting
Connect/disconnect command accept waiting
0 (Normal)
• State of connect/disconnect command accept waiting
In this state, when "1 to 32"
(Note-2)
is set, disconnect execute waiting "-1" is set,
and when "-10" is set, re-connect execute waiting "-1" is set.
Connect/disconnect execute waiting
-1
• State where it is standing by to execute connect/disconnect processing.
(State after "1 to 32
(Note-2)
: Disconnect command" and "-10: Re-connect
command" are set by user side.)
After this state, when "-2: Connect/disconnect execute command" is set by
user side, connect/disconnect processing is executed.
System
side
Disconnect command (Axis No. of servo amplifier to disconnect)
1 to 32
(Note-2)
• Set axis No. "1 to 32"
(Note-2)
of servo amplifier to be disconnected.
If this axis number is set by user side, it only becomes "-1: Disconnect execute
waiting". Set "-2: Disconnect execute command" by user side to actually
disconnect.
Re-connect command
-10
• Set to re-connect the disconnecting servo amplifier.
The disconnecting servo amplifiers for all SSCNET systems are re-connected.
If this setting value is set by user side, it only becomes "-1: Re-connect
execute waiting". Set "-2: Re-connect execute command" by user side to
actually re-connect.
Connect/disconnect execute command
D9112
(Note-1)
-2
• Set to execute connect/disconnect processing.
This setting value is set in the state of "-1: Connect/disconnect execute
waiting". Connect/disconnect device is set to "0" after completion of
connect/disconnect.
(LED display of servo amplifier will be "AA" after completion of disconnection.
Then, turn the power supply of servo amplifier ON. In addition, connect the
SSCNET
cable to servo amplifier and turn the power supply of servo
amplifier ON before re-connect processing.)
User
side
(Note-1) If values except setting value/monitor value are stored, it is set to "0" without processing.
(Note-2) The range of axis No.1 to 8 is valid in the Q172HCPU.
