The Current Limit function on the H100+ model prevents tripping by reducing the output speed (output speed foldback) as the motor current increases and approaches overload condition. PI control is used to monitor the current level and maintain the output frequency above minimum speed to prevent entering into sleep mode. 

AP2.70 Selects Current Limit ENABLE.

AP2.71 through AP2.74 selects Current Limit % and Proportional, Integral Gains and filter time.  

OUT.37 (or any Digital Output Relays) can be set to 0 * "51" Current Limit.
