IDN 55 (S-0-0055) Position Polarity Parameter

The position polarity parameter is used to switch the polarities of position data. Polarities are not switched internally but externally; this means on the in- and output of a closed loop system. The motor shaft turns clockwise when there is a positive position command difference and no inversion. Bit 4 disable or enable the SW-Limit switches. If linear scaling of the position data is selected (refer to IDN 76 ), these Bit will automatic set and it is not possible to disable the position limit values (refer to IDN 49 and 50). If the Position limit switches are set, the drive set a software limit switch fault (Bit 13 in IDN 11 ), if the drive reach the not allowed area. A new value in bit 4 will not become active until the parameter is saved to non-volatile memory and a cold start or warm start ( IDN 128 procedure is initiated
