Remedy
The alarm automatically disappears with BI: p2514 = 0 signal.
An encoder data set has been assigned, however, the encoder data set
does not contain any encoder data (p0400 = 0) or invalid data (e.g. p0408
= 0). Remedy: Check the drive data sets and encoder data sets.
The value range (-2147483648 ... 2147483647) for representing the posi-
tion actual value was exceeded. Remedy: Reduce the traversing range or
position resolution. If necessary reduce the traversing range or position
resolution.
An activated reference function (reference mark search or measuring
probe evaluation) was interrupted. Possible causes:
Encoder fault
•
Reference mark search and measuring probe evaluation simultane-
•
ously activated (BI: p2508 and BI: p2509 = 1 signal).
Activated reference function (reference mark search or measuring
•
probe evaluation) was de-activated (BI: p2508 and BI: p2509 = 0 sig-
nal).
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 (-2147483648 ... 2147483647) for representing
the position actual value.
Check current limits (p0640).
Vector control: Check current controller (p1715, p1717).
U/f control: Check the current limiting controller (p1340 ... p1346).
Increase acceleration ramp (p1120) or reduce load.
Check motor and motor cables for short circuit and ground fault.
Check motor for star-delta connection and rating plate parameterization.
Check power unit / motor combination.
Select flying restart function (p1200) if switched to rotating motor.
Reduce the continuous load.
•
Adapt the load cycle.
•
Check the assignment of rated currents of the motor and power unit.
•
Reduce driving load.
Use power unit with higher energy recovery capability.
For vector control, the regenerative power limit in p1531 can be reduced
until the fault is no longer activated.
Check the converter connection on the motor side for any phase-
•
phase short-circuit.
Rule out that line and motor cables have been interchanged.
•
The signal for "external alarm 1" has been triggered.
Parameters p2112, p2116 and p2117 determine the signal sources for
the external alarm 1... 3.
Remedy: Rectify the cause of these alarms.
