(2) Problem with the
The pulse frequency to be input to the pulse I/O module is too high.
The pulse frequency to be output from the pulse I/O module is too high.
Cause
Check the pulse
be output from ch. B is frequency to be output
high. from the controller.
Check the output
gear in axis mode, the pulse frequency from
pulse frequency to be the controller.
output from Ch. B is
high compared to the
maximum frequency of
the pulse output. [Pr.
PA06], [Pr. PA07] and
[Pr. PB01]
Check the connection
incorrect when the pulse form of the pulse that
I/O module is used in is actually output and
the axis mode. the setting value of
[Pr. PB01].
Replace the controller,
malfunctioning. and then check the
repeatability.
Check the noise,
