7 ELG-Specific Signals (DB 29)
7.2 Signals from ELG (DB 29)
AUTOMATICALLY CONTROLLED CORRECTION OF FA
1 signal: Automatically controlled correction of FA owing to a malfunction. The setpoints
for the following axis are derived from the partial actual values of the leading
axes.
0 signal: The type of link between the following axis and the leading axes specified in the
machine data is effective.
Notes:
• The signal does not have any significance if the gearbox link is not selected
(LINK ACTIVE = 0).
• The machine data specify how long automatically controlled correction of the following
axis is to be effective.
FA1: MD 956
FA2: MD 976
FA3: MD 996
Example of application:
Recognition of link malfunctions.
MAXIMUM ACCELERATION
1 signal: The setpoint for acceleration of the following axis is greater than the maximum
acceleration stated in the machine data. The positional deviation of the following
axis from the leading axes increases. Alarm 2419 "FA 1 acceleration limit" (for
FA 1) is issued.
0 signal: The acceleration of the following axis is less than its maximum acceleration.
Notes:
• The signal does not have any significance if the gearbox link is not selected
(LINK ACTIVE = 0).
• The acceleration limitation for the gearbox link can be deselected with the "Suppression of
acceleration limitation" machine data bits; this also suppresses the corresponding alarm.
Suppression of acceleration limitation:
FA1: MD 5021.3
FA2: MD 5022.3
FA3: MD 5023.3
• The possible or permissible maximum acceleration of the following axis is stated in
machine data MD 276*.
