Then, open the memory screen by pressing an appropriate soft key.
The upper and lower bytes of a parameter error detail number are
displayed in the following addresses:
Axis for which an odd value is set in parameter No. 1023:
> 1C1 (upper byte)
> 1C0 (lower byte)
Axis for which an even value is set in parameter No. 1023:
> 1C3 (upper byte)
> 1C2 (lower byte)
For example, when an invalid parameter setting alarm is caused for the
first axis (set in parameter No. 1023), and 34 is set at address 1C0 and
04 is set at address 1C1 on the memory screen, alarm detail No. is 0434.
Analyzing invalid parameter setting alarms in detail
The detail alarm data basically consists of four digits as shown:
Upper three digits: Indicate the location where an alarm was caused.
Table 2.1.5 lists the displayed numbers and corresponding
parameter numbers.
* Remark: Basically, the lower three digits in a 4-digit
parameter number in the Series 16 are
indicated.
Lowest digit: Indicates the cause of an alarm.
The displayed numbers and their meanings are explained
below:
1: Because the parameter value is beyond the setting range,
a clamped value is used. (This is not an alarm but a
caution. It is not used at present.)
2: The set parameter is invalid. The corresponding
function does not operate.
3: The parameter value is beyond the setting range.
Alternatively, the parameter is not set.
4 to 9: An overflow occurred during internal calculation.
NOTE
To display address 1Cx, search for address 199, then
perform page feed by two pages.
However, page feed by more than two pages causes
a system alarm.
