代码 231117: <location>Encoder 1: Inversion error signals A and B and R

Message value: Drive object: All objects Reaction: A_INFEED: NONE SERVO: ENCODER (IASC/DCBRAKE, NONE) VECTOR: ENCODER (IASC/DCBRAKE, NONE) Acknowledge: IMMEDIATELY Cause: For a square-wave signal encoder (TTL. bipolar. double ended) the A* and B* and R* signals are not inverted with respect to signals A and B and R. Note: For CU310, CUA32, D410, SMC30 (only Order No. 6SL3055-0AA00-5CA0 and 6SL3055-0AA005CA1), the following applies: A squarewave encoder without trac k R is used and the track monito ring (p0405.2 = 1) is activated. See also: p0491 (Motor encoder fault response ENCODER) Remedy: - check the setting of p0405: p0405.2 = 1 is only possible if the encoder is connected at X520. - check the encoder/cable: Does the encoder suppl y TTL signals and the associated inverted signals? Note: For a squarewave encoder without track R, the foll owing jumpers must be set at the encoder connection: - pin 10 (reference signal R) <--> pin 7 (encoder power supply, ground) - pin 11 (reference signal R inverted) <--> pin 4 (encoder power supply) SINAMICS-Alarms Diagnostics Manual (DAsl), 03/2009
