Alarm
Cause
Remedy
A7480: EPOS: Software limit
switch plus reached
The axis is at the position of the software
limit switch plus. An active traversing block
was interrupted.
•
Correct the target position.
•
Change software limit switch plus (CI:
p2581).
A7496: SON enable missing
•
In the IPos control mode or a com-
pound control mode with IPos, no ser-
vo on command is sent to the drive via
Modbus when p29008 = 1.
•
In the IPos control mode, rising edge is
triggered for the P-TRG signal when
the drive is in servo off status.
•
In the PTI control mode, any faults
which is caused by implementing the
"Enable trial run" operation with the V-
ASSISTANT lead to A7496.
•
Send servo on command to the drive via
Modbus
•
Set the drive to servo on status firstly and
trigger a rising edge for the P-TRG signal.
•
Acknowledge the faults firstly and imple-
ment "Enable trial run" again.
A7576: Encoderless opera-
tion due to a fault active
Encoderless operation is active due to a
fault.
•
Remove the cause of a possible encoder
fault.
•
Carry out a POWER ON (power off/on) for
all components.
A7582: Position actual value
preprocessing error
An error has occurred during the position
actual value preprocessing.
Check the encoder for the position actual
value preprocessing.
Refer to F52931.
A7585: P-TRG or CLR active In the PTI mode or a compound mode with
PTI, the P-TRG or CLR function is activat-
ed.
In the PTI mode, deactivate the P-TRG or
CLR function; in the compound mode with
PTI, do not switch to other modes.
A7588: Encoder 2: Position
value preprocessing does not
have a valid encoder
The parameter configuration of PTI coun-
ter is incorrect.
Default the drive and re-configure the param-
eters.
A7805: Power unit overload
I
2
t
Alarm threshold for I
2
t overload of the
power unit exceeded.
•
Reduce the continuous load.
•
Adapt the load duty cycle.
•
Check the assignment of the rated cur-
rents of the motor and motor module.
A7965: Save required
The angular commutation offset was re-
defined and has still not been saved.
In order to permanently accept the new
value, it must be saved in a non-volatile
fashion.
This alarm automatically disappears after the
data has been saved.
