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.
