Current Average Value Monitor Signal - Mitsubishi Electric FR-A820-00046 Instruction Manual

Current average value monitor signal

The output current average value during constant-speed operation and the maintenance timer value
are output to the current average value monitor signal (Y93) as a pulse. The output pulse width can be
used in a device such as the I/O unit of a programmable controller as a guideline for the maintenance
time for mechanical wear, belt stretching, or deterioration of devices with age.
The pulse is repeatedly output during constant-speed operation in cycles of 20 s to the Current av-
erage monitor signal (Y93).
