Altivar 16 AC Drive Option card functions, logic input parameters Reduce current limit Available on: VW3A16201 + VW3A16104 . 1 logic input, either LI1, LI2 or LI3. Function Reduction of maximum current on the Altivar 16. Adjustment 0.5 to 1.5 times the continuous drive output current. Applications Machines which may frequently jam such as conveyors, grinders and extruders. Torque regulation or simple tension-controlled applications. Use with a motor that has a power less than that of the drive. +Speed/- speed Available on: VW3A16201 + VW3A16104 . Logic inputs LI1 and LI2.
Function Increase and decrease speed by using two logic inputs, with or without storing last reference (similar to a motorized potentiometer).
