Fault value (r0949, decimal interpretation):
1: The position actual value (r2521) has exceeded the value range.
2: The encoder position actual value Gn_XIST2 (r0483) or the absolute value after the load gear (r2723) has
exceeded the value range.
3: The maximum encoder value times the factor to convert the absolute position (r0483 and/or r2723) from incre-
ments to length units (LU) has exceeded the value range for displaying the position actual value.
Remedy:
If required, reduce the traversing range or position resolution (p2506).
Increase the fine resolution of absolute position actual value (p0419).
Note for fault value = 3:
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
F07494
LR: Drive Data Set changeover in operation
Message value:
-
Drive object:
SERVO_S110-CAN, SERVO_S110-DP, SERVO_S110-PN
Reaction:
OFF1 (OFF2, OFF3)
Acknowledge:
IMMEDIATELY
Cause:
A Drive Data Set changeover (DDS) with a change of the mechanical relationships (p2503 ... 2506), direction of rota-
tion (p1821) or the encoder assignment (p2502) was requested in operation.
Note:
DDS: Drive Data Set
Remedy:
To changeover the drive data set, initially, exit the "operation" mode.
A07495 (F)
LR: Reference function interrupted
Message value:
-
Drive object:
SERVO_S110-CAN, SERVO_S110-DP, SERVO_S110-PN
Reaction:
NONE
Acknowledge:
NONE
Cause:
An activated reference function (reference mark search or measuring probe evaluation) was interrupted.
- an encoder fault has occurred (Gn_ZSW.15 = 1).
- position actual value was set during an activated reference function.
- simultaneously activate reference mark search and measuring probe evaluation (BI: p2508 and BI: p2509 = 1 sig-
nal).
- activated reference function (reference mark search or measuring probe evaluation) was de-activated (BI: p2508
and BI: p2509 = 0 signal).
Remedy:
- check the causes and resolve.
- reset the control (BI: p2508 and BI: p2509 = 0 signal) and activate the requested function.
Reaction upon F:
OFF1 (OFF2, OFF3)
Acknowl. upon F:
IMMEDIATELY
