3.6 Inverter De-rating Based on Temperature
Note: User needs to adjust the inverter rated current depending on ambient temperature to ensure
the appropriate industrial application.
◆ Notes for using the PM motor
1. The inverter carry frequency (11-01) need to set upper than 6KHz.
2. The rating current of the inverter at 6KHz carry frequency (11-01) (need refer to the
de-rating curve) must be bigger than the PM motor rating current.
◆ Capacitor reforming Guide after long storage
For correct performance of this product after long storage before use it is important that
Inverter Capacitors are reformed according to the guide below:
Storage
time
Procedure to re-apply voltage
≦1year
Apply rated voltage(*1) of inverter in the normal way
Between
1-2 years
Apply rated voltage of inverter to the product for one hour
≧2 years
Use a variable AC power supply to
1. Connecting 25% of inverter rated voltage for 30 minutes.
2. Connecting 50% of inverter rated voltage for 30 minutes.
3. Connecting 75% of inverter rated voltage for 30 minutes.
4. Connecting 100% of inverter rated voltage for 210 minutes.
Once the procedures completed, inverter just can be used normally.
*1：Rated voltage: please connects rated voltage according to model label of inverter.
