Protective Functions
7-32
7.3 Warning function

The warning will be triggered before the protective function is activated, and you can check the conditions
such as overload beforehand.

One of the following warning modes can be selected through the setting of Pr 6.27 Warning latch state
setting: the warning non-latch mode in which the warning is automatically cleared 1 sec. after the cause of
warning is removed, and the warning latch mode in which the warning is kept issued even after the cause of
warning is removed. To clear the latched state, use the alarm clearing procedure described in previous alarm
section.

Note that the battery warning is latched by the encoder: after unlatching at the encoder, the warning is
cleared.

state setup 0 to 3 - Set the latching state of warning.
General warning and extended warning can be specified.

6 37 B Oscillation
detecting level 0 to 1000 0.1% Set the threshold of oscillation detection.
When torque vibration beyond this setting is detected, an
oscillation detection alarm is activated.
If the set value is 0, this function is disabled and the alarm
is not activated.
6 38 R Alarm mask setup -32768 to
32767
- Set the warning detection mask.
To disable detection of a warning, place 1 to the
corresponding bit.

2 -32768 to
32767 -
6 95 A Over-load warning
detection level 0 to 114 % Sets the threshold value for detecting the warning as the
overload load factor increases.
Sets with the overload load factor.
If 0 is set, overload warning detection is performed under
conventional conditions (85% of overload protection
level).
In addition, if other than "Pr6.96 <= Pr6.95 < (Overload
protection level)" is set, overload warning detection is
performed under conventional conditions (85% of
overload protection level).
