5.5 Monitor Data
Error occurrence
(Minute: Second)
The time (minute: second) of error detection is stored in BCD code.
• b15 to b8: Minute
• b7 to b0: Second
The data can be monitored in hexadecimal.

Error history pointer
• The pointer No. for the next error record is stored. A value from 0 to
15 is stored.
• Even when Error reset signal (Y28) is turned on, the data is not
cleared to 0.

Maximum accumulated
pulse value
[When the accumulated pulse error detection function is being executed]
The reference value that is kept in the flash ROM of the QD73A1 is
displayed.
[When the reference value is being measured]
The maximum/minimum accumulated pulse values are stored when the
positioning is executed in the address increasing/decreasing direction.
[In other cases]
0 is stored.

Accumulated pulse
error detection function
status
The status of the accumulated pulse error detection function is
displayed.
0: Normal
1: Accumulated pulse error is being detected
2: Reference value is being measured
0: Normal 204
Reference value
measurement flag
The status of the reference value measurement is displayed.
0: Unmeasured
1: Measured
Check that this area stores 1 before writing data in the flash ROM.
This area becomes 0 at the following timing.
• When the module is started
• When " Accumulated pulse error detection request" is set to 1
and the error detection starts
0: Unmeasured 205
Deviation counter
value (pulse)
• The difference of the values obtained from "Command pulse ×
CMX/CDV" and "Number of feedback pulses × Multiplication" is stored
as a deviation counter value.
• The update cycle is 0.5ms.

Movement amount
after near-point dog
ON (absolute value)
• When OPR starts, "0" is stored.
• When OPR is completed, the movement amount from the near-point
dog ON to the OPR completion is stored as an absolute value.
(Movement amount: Movement amount to OPR completion using
near-point dog ON as "0".)
• The count value is stored for both the near-point dog method and the
count method. (Use the value as a reference value for OPR
adjustment.)
