(6) Synchronous control input axis errors (800 to 899)
These are errors detected at the input axis during synchronous control.
The error codes, causes, processing and corrective actions are shown in Table
1.8.

• Phase compensation amount of
input axis is equal or lower than
the minimum value
(-2147483648), or exceeding the
maximum value (2147483647).
• Set a smaller phase
compensation advance time.
• Decrease the input axis speed.
881
• 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.
882
• 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.
It is controlled
with the
minimum or
maximum
value.
• 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 min to sec
if the speed command time unit
setting is available in the input
axis setting.
• Decrease the input axis speed.
883
• Low voltage at Q172DEX. Operation is
continued. • Replace the battery.
884
• The "[Cd.321] Synchronous
encoder axis control method
(10n)" is set to other
than 0 to 2 at synchronous
encoder axis control request.
Synchronous
encoder axis
control does
not start.
• Set a value within the range.
