Warning
Phase compensation amount of input axis
is equal or lower than the minimum value
(-2147483648), or exceeding the
maximum value (2147483647).
Rotation direction restriction amount of
input axis is equal or lower than the
minimum value (-2147483648), or
exceeding the maximum value
(2147483647).
Monitor speed display of input axis is
equal or lower than the minimum value
(-2147483648), or exceeding the
maximum value (2147483647).
Voltage of the servo amplifier battery
connected with a synchronous encoder
decreased to 3.2V or less.

continues.
6 - 5
Corrective action
• Set a smaller phase compensation
advance time.
• Decrease the input axis speed.
• 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.
• 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.
Replace the battery.
