What F7493 means

LR: Overflow of the value range for position actual value p. 296

Common causes

  • The value range (-214783648 ... 214783647) for the position actual value representation was exceeded. p. 296
  • Note for case = 3: p. 296
  • If the value for the maximum possible absolute position (LU) is greater than 4294967296, then it is not possible to make an adjustment due to an overflow. p. 296
  • Motor encoder with position tracking: EPOS: p29247 * p29244 p. 296
  • Motor encoder without position tracking: For multi-turn encoders: EPOS: p29247 * p29248 * 4096 / p29249 p. 296
  • For single-turn encoders: EPOS: p29247 * p29248 / p29249 p. 296

What to do

  1. If required, reduce the traversing range or position resolution p29247. p. 296
  2. For rotary encoders, the maximum possible absolute position (LU) is calculated as follows: p. 296

Before you service the product, read the safety instructions in the manual p. 2.
