Input axis phase
compensation amount over
Phase compensation amount of input axis
is equal or lower than the minimum value
(-2147483648), or exceeding the
maximum value (2147483647).
The input axis
operation
continues.
It is controlled with
the minimum or
maximum value.
• Set a smaller phase compensation
advance time.
• Decrease the input axis speed.
681
(2A9h)
Input axis rotation direction
restriction amount over
Rotation direction restriction amount of
input axis is equal or lower than the
minimum value (-2147483648), or
exceeding the maximum value
(2147483647).
• Confirm the enabled direction of
the rotation direction restriction
setting. (The setting may be
reversed.)
• Check if the input axis moves to
the reverse direction of the
enabled direction.
682
(2AAh)
Input axis speed display
over
Monitor speed display of input axis is
equal or lower than the minimum value
(-2147483648), or exceeding the
maximum value (2147483647).
The input axis
operation
continues.
The minimum or
maximum value is
displayed as the
speed display of
monitor data.
• Set a lower value if the number of
decimal places for speed
command setting is available in
the input axis setting.
• Switch the units from minute to
second if the speed command
time unit setting is available in the
input axis setting.
• Decrease the input axis speed.
