Cause
In the actual traversing operation, the
target position is less than the software
limit switch minus.
In the actual traversing operation, the
target position is greater than the software
limit switch plus.
The axis is at the position of the software
limit switch minus. An active traversing
block was interrupted.
The axis is at the position of the software
limit switch plus. An active traversing block
was interrupted.
The fixed stop in the traversing block was
reached without the clamping
torque/clamping force having been
achieved.
In the modes "traversing blocks" or "direct
setpoint input/MDI" at the start of motion,
the binector input "no intermediate
stop/intermediate stop" did not have a 1
signal.
In the modes "traversing blocks" or "direct
setpoint input/MDI" at the start of motion,
the binector input "do not reject traversing
task/reject traversing task" does not have a
1 signal.
In the EPOS control mode, no servo on
command is sent to the drive via
PROFINET.
12.1 List of faults and alarms
Remedy
Correct the target position.
•
Change software limit switch minus (CI:
•
p2580).
See also: p2580 (EPOS software limit switch
minus), p2582 (EPOS software limit switch
activation)
Correct the target position.
•
Change software limit switch plus (CI:
•
p2581).
See also: p2581 (EPOS software limit switch
plus), p2582 (EPOS software limit switch
activation)
Correct the target position.
•
Change software limit switch minus (CI:
•
p2580).
See also: p2580 (EPOS software limit switch
minus), p2582 (EPOS software limit switch
activation)
Correct the target position.
•
Change software limit switch plus (CI:
•
p2581).
See also: p2581 (EPOS software limit switch
plus), p2582 (EPOS software limit switch
activation)
Check the torque limits (p1520, p1521).
Connect a 1 signal to the binector input "no
intermediate stop/intermediate stop" and
restart motion.
Connect a 1 signal to the binector input "do
not reject traversing task/reject traversing
task" and restart motion.
Send servo on command to the drive via
PROFINET.
