5.67 Maintenance Alarm Function (P.261)
P.261 “Maintenance Alarm Time”
● When Multi-function output terminal (P.40, P.85) equals 18, maintenance alarm is detecting. It
means that when the inverter runs for the days that reach the parameter P.261 set value of
maintenance alarm time, the multi-function terminal SO-SE or multi-function relay will send out
signal.

<Setting>
1. If motor vibration is generated at higher frequency, adjust the set value of P.286. Gradually
increase the set value by the unit of 1.
2. For the actual application, use the vibration-generating frequency that is lower or higher than half
of the motor rated frequency to determine whether the occurred vibration is a low-frequency
vibration or a high-frequency vibration. That is, if the rated frequency on the name plate of the
motor is 50Hz and the vibration-generating frequency is higher than 25Hz, then this is a
high-frequency vibration.
Note: 1.When the motor load is light, current flow may happen at certain specific operation frequency. This
situation may cause the motor to vibrate slightly. The user can neglect it if this trivial vibration has no
impact on the application.
2. If the current flow is serious (generating vibration), it may cause serious motor vibration or even inverter
over-current. The user can try to adjust the vibration inhibition factor to improve the situation.
