Preparing for Operation
Note 2. If "0" (stall prevention during deceleration) is set in this constant, deceleration
time will be automatically lengthened to prevent overvoltage.

•These constants are used to decrease the output frequency so that the Inverter will
continue operating without stalling.
•Set the constants in percent based on the rated inverter current as 100 percent.
