How do I fix an F67 Current Limit Control Warning code for a DG1 drive?

The current limit control warning is an indication that the drive is in the current limit controller which in this case the torque and load have reached the maximum that the drive is set to supply in which it will limit the output frequency to try and allow the current to back down. When the drive goes into this mode it use a PI loop to control the output frequency to the motor. This current level can be set via the keypad on the drive in the motor control parameter group, typically this value should be 1.15 times the full load amps of the motor so if set to low it is potentially causing the drive to go into this state. If the value is set correctly then the load should be check to be sure it is working properly and that things were sized right.
