6.3.2 Error Check Flowchart

Find the correction to the problem using the following flowchart if the cause of the problem is thought to be the
MP2100/MP2100M or SERVOPACK.
LED indicators on MP2100/MP2100M
front panel S1, S2 are lit in red.
Is a motion program being used?
Check the MSEE instructions in the ladder program
to see the contents of the 1st word (status flag) of
work registers of all motion programs that are
*1
used.
Is there any motion program whose
status flag bit 8 is ON ? (a)
Check the contents of the 2nd word (control
*2
signal) of the MSEE work register of the
motion program that is applied to (a).
Is bit D of the control signal ON?
Check the contents of the 4th word (system
*3
work number) of the MSEE work register of
the motion program that is applied to (a) to
learn the system work number.
Display the contents of the alarm code in
hexadecimal (HEX) on the register list by
using the system work number
Check the alarm code to find the cause.
See 6.5.2 Motion Program Alarm Code List.
* 1. Under each MSEE instruction in ladder programs, the motion program number that is used and the MSEE work
leading register number are displayed.
When bit 8 of the 1st word (status flag: refer to 5-15) of MSEE work is ON, a motion program alarm is occur-
ring (for details on how to refer to the register list, refer to 6.4.2 Accessing System Registers).
<Example> In the figures below, when the MSEE instruction shown on the left is executed in a ladder pro-
gram, DW00000 is the MSEE work leading register number. Therefore, if bit 8 of DW00000 is
ON, it means that a motion program alarm is occurring.
When the motion program number is indicated by a register number as shown on the right, check the corre-
sponding register to learn the motion program number.
