8.2.3 Motion Module Error Displays and Actions Taken
„ Servo Number LED Display
The status LED indicator displays the servo number (1 to 16) when the Motion Module is
normally operating in Online Mode.

Indicator Color When Lit
STATUS Green Displays the servo number or an error.

Hardware reset
status The hardware has been reset. Check the CPU-01 Module
DIP switch settings, and correct them as necessary. If the sta-
tus does not change, replace the Module.
Initializing 1. The system usually enters this status for one to six sec-
onds after the system is turned ON or reset. If the Servo
Module is set up so that an Absolute Encoder is con-
nected, and the interface with the Absolute Encoder
causes an error, this status will last for 30 seconds per
axis.
2. This status lasts if the system enters a permanent loop in
an A Drawing of PLC (CPU1/CPU2).
3. This display indicates that the SVA Module is not regis-
tered in the Module definitions. To use the Module, reg-
ister it in the Module definitions and then specify the
SVA fixed parameters and the setting parameters for
each axis.
4. If 1 to 3 above do not apply, replace the Module.
5. If the problem persists, a hardware error (such as a syn-
chronization error during initialization for the link
between the PLC (CPU1/CPU2) and the SVA Module)
may be the cause of the problem. Replace other Modules
and racks one at a time to isolate the problem cause.
Servo number: No. 1 A servo number (1 to 16) is displayed when the servo is
operating normally without an error or alarm.
Note, however, that this indicator display also appears when
“no axis” is selected.
Servo number: No. 2
Servo number: No. 3
Servo number: No. 4
Servo number: No. 5
