Overspeed detection
Pr.374 Overspeed detection level
Inverter outputs are stopped when the motor speed exceeds the
Pr.374 Overspeed detection level under IPM motor control.
Pr.374
Setting
When the motor speed exceeds the speed set in Pr.374,
0 to 400Hz
overspeed (E.OS) occurs, and the inverter outputs are
stopped.

Pr.503 Maintenance timer
Pr.504 Maintenance timer alarm output set time
When the cumulative energization time of the inverter reaches the
parameter set time, the maintenance timer output signal (Y95) is
output.

This can be used as a guideline for the maintenance time of
peripheral devices.
