◆Stall protective function
Description:When a heavy load is placed on the motor or acceleration timeistoo short during acceleration.
Due to current output too much to lead inverter to over current, it can prevent from motot stall. The inverter
will stop accelerating when output current exceeds Cd69 during acceleration.
Cd68= 0, invalid
= 1, valid
Cd69: setting method:Set inverter rated current to 100%.
※ CT2000FG Cd69 factory setting value is 150%
