Problem Possible solutionProbable cause
The cam output position is
different to the one set using the
teaching function.
Backlash compensation has been
enabled after teaching has been
performed.
With the backlash compensation
already enabled, perform the
teaching operation again.
g
With backlash compensation
enabled, the load side (driven
side) instead of the Resolver axle
(drive side) has been manually
rotated and teaching performed.
(Backlash compensation will work
in reverse.)
Manually rotate the Resolver axle
(drive side) and perform teaching
again.
Teaching has been performed
while the Resolver is rotating (less
than 4 r/min).
Perform teaching again with the
Resolver stationary.
Use the trial operation and
adjustment operation functions to
adjust the cam program (ON/OFF
angle data).
When the speed increases, the
timing of peripheral device
operation is late.
The advance angle compensation
function is not used.
Set the advance angle
compensation function (Function
No. b, Parameter No. 3 to 5 and
Function No. H and Parameter
No. 2) and turn OFF the power
and turn it ON again.
The advance angle compensation
function is not enabled.
Enable the advance angle
compensation function (Function
No. H, Parameter No. 2) and turn
OFF the power and turn it ON
again.
