Overview of Alarms
SINAMICS-Alarms
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 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).
207594 <location>Encoder 2: Value range for position actual value exceeded
Message %1
value:
Drive object: SERVO, VECTOR
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 "adjustment absolute measuring system" status is
reset.
