2. Direct encoder
p2506
p2506 * p0421 for multiturn encoders
F07494 LR: Drive Data Set changeover in operation
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
Reaction: NONE
Acknowledge: NONE
Cause: An activated reference function (reference mark search or measuring probe evaluation) was interrupted.
Possible causes:
- 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.
A07496 EPOS: Enable not possible
Reaction: NONE
Acknowledge: NONE
Cause: It is not possible to enable the basic positioner because at least one signal is missing.
Alarm value (r2124, interpret decimal):
1: EPOS enable missing (BI: p2656).
2: Position actual value, valid feedback signal missing (BI: p2658).
See also: p2656 (EPOS enable basic positioner), p2658 (EPOS pos. actual value valid feedback signal)
Remedy: Check the appropriate binector inputs and signals.
A07497 LR: Position setting value activated
Reaction: NONE
Acknowledge: NONE
Cause: The position actual value is set to the value received via CI: p2515while BI: p2514 = 1 signal. A possible system
deviation cannot be corrected.
Remedy: Not necessary.
The alarm automatically disappears with BI: p2514 = 0 signal.
A07498 (F) LR: Measuring probe evaluation not possible
Reaction: NONE
Acknowledge: NONE
Cause: When evaluating the measuring probe, an error occurred.
Alarm value (r2124, interpret decimal):
6:
The input terminal for the measuring probe is not set.
4098:
Error when initializing the measuring probe.
4100:
The measuring pulse frequency is too high.
> 50000:
The measuring clock cycle is not a multiple integer of the position controller clock cycle.
