(2) PCPU error cause(D9184) .......Data from the PCPU to the SCPU
This register is used to identify the nature of errors occurring in the PCPU part of
the servo system.

PCPU operation synchronization time over
3
PCPU software fault 2
30
PCPU/SCPU hardware fault
All axes stop immediately,
after which operation
cannot be started.
Reset with the reset key.
200
201
Hardware fault of module loaded on motion main
base unit or extension base unit.
2 0 0
Indicates the slot number (0 to 7) where
the module with the fault is loaded.
Indicates the stage number of the base on
which the module with the fault is loaded.
0 : Main base
1 : Extension base (1st extension stage)
Reset with the reset key.
If the error reoccurs after
resetting, the relevant
module or the relevant
slot (base unit) is
probably faulty: replace
the module/base unit.
250
251
SSCNET interface hardware fault
2 5 0
Faulty SSCNET No.
0 : SSCNET 1 (Amplifier interface)
1 : SSCNET 2 (PC link interface)
Exchange the CPU unit.
300
PCPU software fault 3
All axes stop immediately,
after which operation
cannot be started.
Reset with the reset key.
(3) Servo amplifier classification (D9185 to D9186) .......Data from PCPU to SCPU
On switching on the power to the servo system CPU or resetting, the servo
amplifier type set in the system settings is set in these devices.
