Operation frequency

I am planning to operate the FR-E520-0.4K in the following cycle:
Does this affect the life of the inverter?
Operation: 10 seconds
Stop: 10 seconds
Frequency: 70 Hz
Acceleration time: 1.0 sec
Deceleration time: 0.1 sec
Signals input to the inverter are fed directly from the programmable controller output module.
Operates for 24 hours per day.

Answer

I cannot answer clearly because the load is unknown.

The operation cycle of operating for 10 seconds and stopping for 10 seconds is OK, but it is questionable whether the inverter decelerates from 70 Hz to 0 Hz in 0.1 seconds.

Check the load condition and choose the right inverter and brake resistor.

For the life, the heat generation amount increases since the cycle time is short, and the temperature inside the inverter rises, affecting its life. In general, the life of the capacitor used in the inverter shortens in proportion to the temperature. (There is a rule that the capacitor life is reduced to the half as its temperature rises by 10 deg C.)
