Status
System check in progress
Power of the servo amplifier was switched on at the condition that the power of
the servo system controller is off.
The control axis No. set to the auxiliary axis number setting switches (SW2-5 and
SW2-6) and the axis selection rotary switch (SW1) do not match the one set to the
servo system controller.
A servo amplifier malfunctioned, or communication error occurred with the servo
system controller or the previous axis servo amplifier. In this case, the indication
changes as follows.
"Ab" → "AC" → "Ad" → "Ab"
The servo system controller is malfunctioning.
During initial setting for communication specifications
Initial setting for communication specifications completed, and then it synchronized
with servo system controller.
During initial parameter setting communication with servo system controller
During the servo motor/encoder information and telecommunication with servo
system controller
During initial signal data communication with servo system controller
The process for initial data communication with the servo system controller is
completed.
The power supply of servo system controller is turned off during the power supply of
servo amplifier is on.
The ready off signal from the servo system controller was received.
The ready off signal from the servo system controller was received.
The ready off signal from the servo system controller was received.
The alarm No. and the warning No. that occurred is displayed. (Refer to chapter 8.
(Note 4))
