error analysis and elimination
Error response: "Everything Off", as in Table 11-2
Limit switch passed: in "Control" or "Correction" operating mode
The limit switch position is passed by the necessary stopping
distance.
Set actual value is not executed.
Following acknowledgment of the error, it is possible to tra-
verse to the working range.
Alter value of software limit switch (MD21)
Disable limit switch monitoring!
(With the limit switches (MD21/22) disabled, the travel range
limits are established by the maximum allowable values for
the limit switches).
