Over-Current Stall Prevention during Acceleration
Unit: 1
Settings 20 to 250% Factory Setting: 170
0: disable
 A setting of 100% is equal to the Rated Output Current of the drive.
 During acceleration, the AC drive output current may increase abruptly and exceed the value
specified by Pr.06.01 due to rapid acceleration or excessive load on the motor. When this
function is enabled, the AC drive will stop accelerating and keep the output frequency constant
until the current drops below the maximum value.
 When it stalls due to the small motor power or operate with factory setting, please decrease
the setting of Pr.06.01.
 When the acceleration time is obstruction in the application, it is not suitable to use this
function. The solution are:
1. moderate increase the acceleration time
2. setting Pr.01.16 (Auto acceleration / deceleration (refer to Accel/Decel time setting)) to 1, 3
or 4.
