This value sets the current limit for the Over Current Stall Prevention function. During
acceleration, a heavy loaded motor may require very high current. If the current
reaches the value programmed in Pr 06-03, the drive will stop acceleration, hold speed
and wait for the current to dissipate in the motor. Once the current has fallen below the
limit set in 06-03, the drive will begin to accelerate to command speed as shown in the
graph below.
