SINAMICS G120D List Manual (LH14), 01/2013
Fault value (r0949, interpret decimal):
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 multiplied by the factor to convert the absolute position (r0483 and/or r2723) 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.
Re alarm value = 3:
Reducing the position resolution and conversion factor:
- reduce the length unit (LU) per load revolution for rotary encoders (p2506).
- increase the fine resolution of absolute position actual values (p0419).
A07594 (F, N) Encoder 2: Value range for position actual value exceeded
Reaction: NONE
Acknowledge: NONE
Cause: The value range (-2147483648 ... 2147483647) for the position actual value representation was exceeded.
When the overflow occurs, the "referenced" or "absolute encoder adjusted" 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 (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.
Re alarm value = 3:
Reducing the position resolution and conversion factor:
- reduce the length unit (LU) per load revolution for rotary encoders (p2506).
- increase the fine resolution of absolute position actual values (p0419).
A07596 (F) Encoder 1: Reference function interrupted
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.
A07597 (F) Encoder 2: Reference function interrupted

- simultaneously activate reference mark search and measuring probe evaluation (BI: p2508 and BI: p2509 = 1 sig-

- 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.
