Correction Parameters - Siemens SIMATIC S5 Manual

IP 266
Following error monitoring
You can choose between "ENABLE" and "DISABLE". If you choose "DISABLE", the
following error is no longer monitored and may therefore exceed the maximum
value of 99.999.
Zero-speed monitoring
The IP 266's "Zero-speed monitoring" function also monitors the following error
(difference between actual value and setpoint). In contrast to following error
monitoring, zero-speed monitoring is effective only when the drive is at a
standstill. Because the following error is expected to be very small when the drive
is at zero speed, the value range is more closely restricted, being only from 0.001
to 64.999. When this function has been activated, the error message "Zero-speed
monitor responded" is displayed on the programmer. Aside from this error
message, there is no further reaction of any kind.
Note:
The tolerance limit for zero-speed monitoring may not exceed the maximum
following error.

Correction Parameters

Tool wear necessitates adjustments to the plant or the program. These
adjustments can be made via various correction parameters.
The use of zero offsets makes it possible to invoke a subroutine in the traversing
program for performing similar or identical positioning operations.
