Patent ID: 8461794

Claim:
A method for controlling a servo-drive in which the servo-drive is controlled during each control process by means of a two-position controller whose control signal is a current signal for actuation of the servo-drive, the method comprising: storing a program for controlling a charging of the servo-drive, the program defining a succession of switching point pairs, each pair defining an upper switching point and a lower switching point, wherein for each switching point pair, the upper switching point is assigned one maximum current value and the lower switching point is assigned one minimum current value, wherein the upper and lower switching points are separated by a predefined minimum interval, wherein the respective minimum current value defining the lower switching point in each switching point pair increases throughout the succession of switching point pairs, and for a predefined first time period, alternatively switching a switch between an open, charging position in which the servo-drive is charged and a closed, discharging position in which the servo-drive is discharged, according to the succession of switching point pairs, such that each upper switching point triggers a switch from the open, charging position to the closed, discharging position, and each lower switching point triggers a switch from the closed, discharging position to the open, charging position.
