A07557
A07558
Reference point coordinate not in
the permissible range
The received reference point coordinate when adjusting the encoder via
connector input CI: p2599 lies outside half of the encoder range and
cannot be set as actual axis position. Remedy: Correct reference point
A07577
A07578
Measuring probe evaluation not
possible
• Set the input terminal for the measuring probe (p0488, p0489 or
p2517, p2518).
• Reduce the frequency of the measuring pulses at the measuring
probe.
A07581
Position actual value processing
Check the encoder for the actual position value processing.
A07584
Position setting value activated The alarm automatically disappears with BI: p2514 = 0 signal.
A07587
A07588
Position actual value processing
does not have a valid encoder
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.
A07593
A07594
Value range for position actual
value exceeded
The value range (-2147483648 ... 2147483647) for representing the
position actual value was exceeded. Remedy: Reduce the traversing
range or position resolution. If required, reduce the traversing range or
A07596
A07597
Reference function interrupted An activated reference function (reference mark search or measuring
probe evaluation) was interrupted. Possible causes:
• Encoder fault
• Reference mark search and measuring probe evaluation
simultaneously 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
signal).
F07599
F07600
Adjustment not possible 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.
F07801 Motor overcurrent 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.
A07805 Drive: Power unit overload I2t
• Reduce the continuous load.
• Adapt the load cycle.
• Check the assignment of rated currents of the motor and power unit.
