This function acts as an adjustable current limit when operating at a con-
stant speed. It can be used to prevent the load current from exceeding the
inverter's over current level, thereby preventing shut down of the inverter
with an E.OC fault. When the load level reaches the adjusted value, the
output frequency is reduced until the load drops below the adjusted value,
after which the frequency is increased again to the previous value. Setting
the value too low may prevent the motor from running at the desired speed.
CP. 3 displays "SSL" when the function is active.

Utilization
This function acts as an adjustable current limit during acceleration or
deceleration. It can be used to prevent the load current from exceeding the
inverter's peak current rating, thereby preventing shut down with an E.OC
fault. When the load level reaches the adjusted value, the acceleration or
deceleration is stopped until the load drops below the adjusted value. Note:
if this parameter is adjusted too low, the motor may not be able to accelerate
to full speed. The motor will run at a low speed. CP.3 displays "LAS" when
the function is active.
