Warning Functions
A warning is generated before the protective function is activated. This allows you to check the status such as an
overload in advance.
In principle, a warning will automatically return to the state where it is not issued if the faulty state is
corrected. However, the warning state will be kept during latch duration as shown in the following figure.
To clear a latched warning before the latch time expires, perform the procedure taken to execute an alarm
clear.

*1 For “
”, you can set a value between 1 and 10s in Pr6.27 “Alarm latch time selection”, or set no ti
me limit. Battery warnings and life warnings are set with “no time limit.”
*2 Select the warning output by the Warning output signal 1 (WARN1) and Warning output signal 2 (W
ARN2) using Pr4.40 “Selection of alarm output 1” and Pr4.41 “Selection of alarm output 2”. If set to
0, OR output of all warnings will be output. Also, do not set a value other than the set values liste
d in the above table.
*3 Each warning detection can be masked using Pr6.38 “Alarm mask setup”. The supported bits are listed in the
table. Bit=1 masks the warning detection.
*4 The encoder overheat is effective only during using the 20 bit incremental serial encoder . It becomes invalid for other
encoders.
