F07600 (A) Encoder 2: Adjustment not possible
Message value: Drive data set: %1
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Drive object: VECTOR_G
Reaction: OFF1 (NONE, OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: The maximum encoder value times the factor to convert the absolute position (r0483 and/or r2723) from increments
to length units (LU) has exceeded the value range (-2147483648 ... 2147483647) for displaying the position actual
value.
Remedy: 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.
For rotary encoders, the maximum possible absolute position (LU) is calculated as follows:
1. Motor encoder without position tracking:
p2506 * p0433 * p2505 / (p0432 * p2504)
p2506 * p0433 * p2505 * p0421 / (p0432 * p2504) for multiturn encoders
2. Motor encoder with position tracking for measuring gear:
p2506 * p0412 * p2505 / p2504
3. Motor encoder with position tracking for load gear:
p2506 * p2721 * p0433 / p0432
4. Motor encoder with position tracking for load and measuring gear:
p2506 * p2721
5. Direct encoder without position tracking:
p2506 * p0433 / p0432
p2506 * p0433 * p0421 / p0432 for multiturn encoders
6. Direct encoder with position tracking for measuring gear:
p2506 * p0412
For a linear encoder, the following must be maintained:
- p0407 * p2503 / (2^p0419 * 10^7) <= 1.0
Reaction upon A: NONE
Acknowl. upon A: NONE
F07601 (A) Encoder 3: Adjustment not possible
