L122 Deliverance Operation (Input power detection level)
L123 Deliverance Operation (Direction Calculation Setup)
L124 Deliverance Operation (Direction Calculation Delay Timer)
This function calculates the best direction to perform the movement (FWD or REV), when a vertical load
with a counterweight has to be moved and the requirements about the input power are very restrictive (i.e.,
supplying the inverter by means of a UPS system or batteries).
■
Input power detection level (L122)
On this parameter input power detection level is set. This level is used to decide to which direction run the
motor.
