We are using S120 CU310, 6SL3040-1LA00-0AA0 drive with attached motor. Machine is running fine with correct positioning, but after power restart the encoder is losing the position. Absolute encoder stores home position of 6 digits after power off and on, for example home position of 774500 (6 digits). In our case home points coordinates are 7745000 (7 digits) so the drive is not storing home point coordinates / position after power off and on. Please advise how we can configure the absolute encoder that the encoder does not lose its position after power restart. For reference: Manual: Drive Functions Manual, (FH1), 07/2007 Edition, 68L3097-2AB00-0BP4 Absolute encoder adjustment Absolute encoders must be adjusted while commissioning. After the machine has been powered-down the position information of the encoder is kept. When p2507 = 2 is entered, using the reference point coordinate in p2599, an offset value (p2525) is determined. This is used to calculate the position actual value (r2521). Parameter p2507 signals the adjustment with a "3" - in addition bit r2684.11 (reference point set) is set to "1"- The offset of the encoder adjustment (p2525) should be saved in a non-volatile fashion (RAM to ROM) to permanently save it. ------------------------------------------------------------------------------------------ |
