W-2WAY ECO-i SYSTEM
Control Functions
3-6-4. Roadmap Control after Trip
When restarting after the trip stop occurs, the horsepower may increase slowly depending on the trip counter value.
(1) If trip counter =1, the horsepower increases at a speed that is 1/2 of ordinary roadmap control.
(2) If trip counter=2, the horsepower increases at a speed that is 1/3 of ordinary roadmap control.
The trip counter will be cleared if no trip occurs within 10 minutes after operation starts.
(2) Current Protection
Inverter compressor current control is composed of primary current control and secondary current control. Cur-
rent protection control for the inverter compressor is performed by self-protection in the inverter circuit, and
does not increase or decrease the compressor capacity.
