14. Protective function ■
◆Stall prevention limit during constant speed
Description：A heavy load is placed on the motor when constant operation and makes inverter output current
exceed Cd74 setting value. The inverter will automatical reduce output frequency to prevent the motor from
stall (OC/OL). When a load disappeared or lightened and makes inverter output current be samller than Cd74
setting value. The inverter will automatical accelerate to work frequency.
Cd73= 0, invalid
= 1, valid, decelerated by Cd11 deceleration time.
Cd74 setting method: Set 100% as inverter rated current.
