<8> Set an abnormal-load detection alarm level.
Perform several different operations (sample machining program,
simultaneous all-axis rapid traverse acceleration/deceleration,
etc.), and observe estimated disturbance values, and measure the
maximum (absolute) value.
Then, set up an alarm level.

Abnormal-load detection alarm level
2104 1104
Alarm level conversion uses the following expression.
[When the digital check board is used]
Alarm level = maximum estimated disturbance value (A)/
maximum amplifier current (A) × 7282 + (500 to 1000
approximately)
[When the analog check board is used]
Alarm level = maximum estimated disturbance (V)/4.4 × 7282
+ (500 to 1000 approximately)

NOTE
1 Add some margin (usually about 500 to 1000) to the
alarm level to be set.
2 If the "abnormal-load detection alarm level"
parameter is reset to 0, no abnormal-load alarm
detection is performed.
