Message value: Drive object: SERVO, VECTOR Reaction: OFF1 (OFF2, OFF3) Acknowledge: IMMEDIATELY Cause: The ratio between the multiturn resolution and the modular range (p2576) is not an integer number. This results in the adjustment being set back, as the position actual value cannot be reproduced after power-off/power-on. Remedy: Make the ration between the multiturn resolution and the modulo range an integer number. The ratio v is calculated as follows: 1. Motor encoder without position tracking: v = (p0421 * p2506 * p0433 * p2505) / (p0432 * p2504 * p2576) 2. Motor encoder with position tracking for the measuring gear: v = (p0412 * p2506 * p2505) / (p2504 * p2576) 3. Motor encoder with position tracking for the load gear: v = (p2721 * p2506 * p0433) / (p0432 * p2576) 4. Motor encoder with position tracki ng for the load and measuring gear: v = (p2721 * p2506) / p2576 5. Direct encoder without position tracking: v = (p0421 * p2506 * p0433) / (p0432 * p2576) 6. Direct encoder with positi on tracking for the measuring gear: v = (p0412 * p2506) / p2576 Note: With position tracking, it is recommended that p0412 and p2721 are changed See also: p0412, p0432, p0433, p2504, p2505, p2506, p2576, p2721
