Cause: The value range (-2147483648 ... 2147483647) for the position actual value representation was exceeded.
When the o
ver󹪞ow occurs, the "homed" or "adjustment absolute measuring system" status is reset.
Fault value (r0949, interpret decimal):
1: The position actual value (r2521) has exceeded the value range.
2: The encoder position actual value Gn_XIST2 has exceeded the value range.
3: The maximum encoder value times the factor to convert the absolute position Gn_XIST2 from increments 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).
Note f
or 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 over󹪞ow.
For rotary encoders, the maximum possible absolute position (LU) is calculated as follows:
p2506 * p2505 / p2504
p2506 * p2505 * p0421 / p2504 for multiturn encoders
F07494 LR: Drive Data Set changeover in operation
Message class: Application/technological function faulted (17)
Message value: -
Component: None
Response: OFF1
Acknowledgment: IMMEDIATELY
Cause: A Drive Data Set changeover (DDS) with a change of the mechanical relationships (p2503 ... 2506), direction of rotation
(p1821) or t
he encoder as
signment (p2502) w
as requested in operation.
Note:
DDS: Drive Data Set
Remedy: To changeover the drive data set, initially, exit the "operation" mode.
A07495 LR: Homing function interrupted
Message class: Application/technological function faulted (17)
Message value: -
Component: None
Response: NONE
Acknowledgment: NONE
Cause: An activated homing function (homing mark search or measuring probe evaluation) was canceled.
P
ossible causes:
- An encoder fault has occur
red (Gn_ZSW.15 = 1).
- Position actual value was set during an activated homing function.
- Homing mark search and measuring probe evaluation simultaneously activated.
- Activated homing function (homing mark search or measuring probe evaluation) was de-activated.
Remedy: - Check the causes and resolve.
- Reset the contr
ol and activate the required function.
A07496 EPOS: Enable not possible
Message class: Application/technological function faulted (17)
Message value: %1
Component: None
Response: NONE
