(4) SSCNET control (status) (SD508) ............................ Monitor device
SSCNET control (status) (SD508) stores the executing state for
connect/disconnect of SSCNET communication and start/release of amplifier-
less operation.
• 0 .............. Command accept waiting
• -1 ............. Execute waiting
• -2 ............. Executing
Refer to the "Q173D(S)CPU/Q172D(S)CPU Motion controller Programming
Manual (COMMON)" for details of the SSCNET control function.
(5) Test mode request error information (SD510, SD511)
............................. Monitor device
If there are operating axis at a test mode request using MT Developer2, a test
mode request error occurs, the test mode request error flag (SM510) turns on,
and the during operation/stop data of each axis are stored.

(6) Motion CPU WDT error cause (SD512) ................... Monitor device
This register is used as judgement of the error contents in the Motion CPU.
Error code Error cause
Operation when error
occurs
Action to take
1 S/W fault 1
All axes stop immediately,
after which operation
cannot be started.
• Reset the Multiple CPU system.
• If the an operation cycle time over reoccurs after resetting, or a
main cycle is lengthened (more than 1.0[s]),
1) Change the operation cycle into a large value in the system
setting.
2) Reduce the number of command execution of the event task
or NMI task in the system setting.
2
Operation cycle time over
4 WDT error • Reset the Multiple CPU system.
• If the error reoccurs after resetting, explain the error symptom
and get advice from our sales representative.
