1. TROUBLESHOOTING FOR SERVO AMPLIFIER (DRIVE UNIT)
1 - 113
Alarm No.: F6 Name: Simple cam function - Cam control warning
Alarm content
The cam axis position restoration at a time of cam control start was a failure.
The cam control is not normal.
Detail
No.
Detail name Cause Check method Check result Action Target
F6.1 Cam axis one
cycle current
value
restoration
failed
(1) The cam axis one cycle
current value
corresponding to the
feed current value at
cam control start
cannot be restored.
(It occurs in a
reciprocating motion
pattern of the cam.)
Check if the feed
current value is within
the stroke in a
reciprocating motion
pattern of the cam. The feed current
value is the outside
of the stroke. Move the feed
current value to
within the stroke in a
reciprocating motion
pattern of the cam.
Or set the cam
standard position
within the stroke in a
reciprocating motion
pattern of the cam. [A]

F6.2 Cam axis feed
current value
restoration
failed
(1) The difference
(command unit)
between the restored
cam axis feed current
value and the
command position at
cam control start is
bigger than "in-position
range".
Check if the
difference (command
unit) between the
restored cam axis
feed current value
and the command
position at cam
control start is in the
"in-position range". The difference of the
command position
(command unit) is
not within "in-
position range". Calculate the cam
axis feed current
value to be restored,
move the command
position to the
position, and then
start the cam control.
(For the calculation
method, refer to
section 12.1.7 (2) of
"MR-J4-_A_-RJ
Servo Amplifier
Instruction Manual
(Positioning Mode)",
and section 6.2.7 (2)
of MR-J4-_GF_(-RJ)
Servo Amplifier
Instruction Manual
(I/O Mode).)
Or set a larger
setting value to "in-
position range" when
the setting value is
extremely small,
such as 0.
F6.3 Cam
unregistered
error
(1) Cam data has never
been written.
Check if the cam data
was written. It was not written. Write the cam data.
It was written. Check (2).
(2) The cam data of the
specified cam No. was
not written.
Check if the cam data
of the specified cam
No. was written. It was not written. Write the cam data
of the specified cam
No.
It was written. Check (3).
(3) Cam data has changed
due to a servo amplifier
malfunction.
Replace the servo
amplifier, and then
check the
repeatability. It is not repeatable. Replace the servo
amplifier.
F6.4 Cam control
data setting
range error
(1) An out of range value
is set to the cam
control data.
Check the setting of
the cam control data. The setting is
incorrect. Set it correctly.
F6.5 Cam No.
external error
(1) An out of range value
is set to the cam No.
Check the setting of
the cam No. The setting is
incorrect. Set it correctly.
