Current Limit is a circuit designed to limit the amount of current a motor can draw in the event of an overload condition. Without a current limiting circuit a DC motor could draw several times its rated current. If the overload condition was not cleared in a timely manner, a motor could suffer severe damage. Setting the current limit properly can provide more time to identity and clear overload conditions. The Current Limit circuit constantly monitors the amount of current a motor demands. If the motor current draw exceeds the limit set by the Current Limit trim pot, the drive begins to lower the amount of voltage it sends to the motor. By lowering the voltage to the motor, the drive is essentially limiting the current. If the overload condition gets worse, the drive will further reduce the voltage it sends to the motor. Turning the current limit CW increases the current limit level the motor will be allowed to draw.
