Chapter 5 Description of Parameter Settings

6 - 01 Over-Current Stall Prevention during Acceleration Factory Setting: d170

Settings d 20 to d 250% Unit: 1%

& A setting of 100% is equal to the Rated Output Current of the drive.

& During acceleration, the AC drive output current may increase abruptly to

exceed the value specified by Pr.6-01 due to rapid acceleration or excessive

load on the motor. When this function is enabled, the AC drive will stop

accelerating and maintaining a constant output frequency. The AC drive will

only resume acceleration when the current drops below the maximum value.

6 - 02 Over-current Stall Prevention during Operation Factory Setting: d 170

Settings d 20 to d 250% Unit: 1%

& During the steady-state operation with motor load rapidly increasing, the AC

drive output current may exceed the limit specified in Pr.6-02. When this

occurred, the output frequency will decrease to maintain a constant motor

speed. The drive will accelerate to the steady-state output frequency only

when the output current drops below the level specified by Pr.6-02.
