1 - 67
Alarm No.: 69 Name: Command error
Alarm content
The command position exceeded 32 bits (-2147483648 to 2147483647) when the software limit is
activated.
The command position exceeded 30 bits (-536870912 to 536870911) from the value that was set when the
software limit was activated.
After the detection of LSP (Forward rotation stroke end) or LSN (Reverse rotation stroke end), the
command position exceeded 30 bits (-536870912 to 536870911) from the detected position.
After the detection of FLS (Upper stroke limit) or RLS (Lower stroke limit), the command position exceeded
30 bits (-536870912 to 536870911) from the detected position.

No.
Detail name Cause Check method Check result Action Target
69.1 Forward
rotation-side
software limit
detection -
Command
excess error
(1) The command position
exceeded 32 bits when
the software limit is
activated.
Check if the command
position is correct. The command
position was set to
32 bits or more. Set the command
position correctly. [GF]
The command
position was set
correctly.
Check (2).
(2) The command position
exceeded 30 bits from
the value that was set
when the software limit
was activated.
Check if the parameter
settings of the
software limit ([Pr.
PT15] to [Pr. PT18]) to
the command position
are correct. It was set within the
command position. Set [Pr. PT15] to
[Pr. PT18] correctly.
It was set correctly. Check (3).
(3) The controller is
malfunctioning.
Replace the controller,
and then check the
repeatability. It is not repeatable. Replace the
controller.
It is repeatable. Check (4).
(4) Something near the
device caused it.
Check the noise,
ambient temperature,
etc. It has a failure. Take
countermeasures
against its cause.
69.2 Reverse
rotation-side
software limit
detection -
Command
excess error
Check it with the check method for [AL. 69.1].
69.3 Forward
rotation stroke
end detection -
Command
excess error
(1) The command position
exceeded 30 bits from
the detected position
after the detection of
LSP (Forward rotation
stroke end).
Check the command
position. The command
position was set to
30 bits or more. Check operation
pattern.
It was set correctly. Check (2).
(2) The forward rotation
stroke limit switch is not
connected to LSP
(Forward rotation
stroke end).
Check if the limit
switch is connected
correctly. It is not connected. Connect it correctly.
It is connected. Check (3).
(3) The controller is
malfunctioning.
Replace the controller,
and then check the
repeatability. It is not repeatable. Replace the
controller.
It is repeatable. Check (4).
(4) Something near the
device caused it.
Check the noise,
ambient temperature,
etc. It has a failure. Take
countermeasures
