9.12 Connect/Disconnect Function of SSCNET Communication
■System monitor data
Procedure to connect/disconnect
Procedure to connect/disconnect at the exchange of servo amplifiers or SSCNET cables is shown below.
■Procedure to disconnect
1. Set the axis No. to disconnect in "[Cd.102] SSCNET control command". (Setting value: 1 to the maximum control axes)
2. Check that "-1: Execute waiting" is stored in "[Md.53] SSCNET control status". (Disconnect execute waiting)
3. Set "-2: Execute command" in "[Cd.102] SSCNET control command".
4. Check that "1: Disconnected axis existing" is stored in "[Md.53] SSCNET control status". (Completion of disconnection.
"20: Servo amplifier has not been connected" is stored in "[Md.26] Axis operation status".)
5. Turn OFF the servo amplifier's power supply after checking the LED display "AA" of servo amplifier to be disconnected.
■Procedure to connect
1. Turn ON the servo amplifier's power supply.
2. Set "-10: Connect command of SSCNET communication" in "[Cd.102] SSCNET control command".
3. Check that "-1: Execute waiting" is set in "[Md.53] SSCNET control status". (Connect execute waiting)
4. Set "-2: Execute command" in "[Cd.102] SSCNET control command".
5. Check that "0: Command accept waiting" is set in "[Md.53] SSCNET control status". (Completion of connection)
6. Resume operation of servo amplifier after checking "0: Standby" in "[Md.26] Axis operation status" of the connected axis.
When "-1: Execute waiting" is set in "[Md.53] SSCNET control status", the command of execute waiting can
be canceled if "0: No command" is set in "[Cd.102] SSCNET control command".
