6.3.2 MP2300 Error Check Flowchart
Find the correction to the problem using the following flowchart if the cause of the problem is thought to be the
MP2300 or SERVOPACK.
* 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 (status flag: See
5.2.4 ( 1 ) Motion Program Status Bits (DA
+0)
) of the 1st word of the MSEE
work leading register is ON, a motion program alarm is occurring. (For information on how to read 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 program,
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 corresponding
register to learn the motion program number.
* 2. For details on control signals, refer to
5.2.4 ( 2 ) Motion Program Control Signals (DA
+1)
.
* 3. For details on system work number, refer to
5.2.4 ( 4 ) System Work Number (DA
+3)
.
