Error details and cause
The fixed scan system process time is error.
There is a factor that the execution of the home position
return is needed in the absolute position system.
• The home position return has never been executed
after the system start.
• The home position return is started, but not completed.
• The absolute value data in the Motion CPU
disappeared due to the reasons such as battery fault.
• Absolute position erase of servo amplifier was detected.
• At servo amplifier power-on, a communication error
occurred between the servo amplifier and encoder.
• "Rotation direction selection" of the servo parameter is
changed.
The interpolation control unit of the parameter block is
different from the control unit of the fixed parameters.
During operation, the "Encoder current value [pulse]" was
mismatched with the "Feedback current value [pulse]"
(encoder effective bit number). It is always checked after
the servo amplifier power supply on (in both servo ON and
OFF states).
The motor travel value while the power is off exceeded the
"Allowable travel during power-off" set in the "Amplifier
setting" at servo amplifier power-on.
• The set JOG speed is higher than the JOG speed limit
value.
• The set JOG speed limit value is out of the control unit
range.
Both of forward and reverse rotations were set at the
simultaneous start for the JOG operation.
The manual pulse generator input magnification is outside
the range of 1 to 10000.
The control operation cycle combination of the manual
pulse generator start specified axis is unmatched.
The manual pulse generator start specified axis number is
more than 4.
The manual pulse generator smoothing magnification is
outside the range of 0 to 59.
• The speed after the change is out of the range of 0 to
Speed limit value. (Unable to change to a minus speed)
• The absolute speed value after the change is out of the
range of 0 to Speed limit value.
• The speed from "command speed of program 
override ratio" is out of the range of 0 to Speed limit
value.
• The speed from "speed change request  override ratio"
is out of the range of 0 to Speed limit value.
Corrective action
Please decrease the following settings to make the "fixed
scan system process monitor time (SD598)" less than
222[s].
• Mark detection
• High-speed input request signal
• Axis setting parameter - External signal parameter
(DOG signal)
• Operation points of input module
• Digital oscilloscope (probe setting number)
Execute the home position return after checking the
batteries of the Motion CPU module and the servo
amplifier.
Combine the control unit of the fixed parameter and
parameter block.
Check the motor and encoder cables.
• Check the position.
• Check the battery of the servo amplifier."
• Set within the range of 1 to JOG speed limit value.
• Set the JOG speed limit value within the range.
Set either forward rotation or reverse rotation.
Set the manual pulse generator input magnification within
the range of 1 to 10000.
Specify the axis No. whose control operation cycle
combination can match.
Set the manual pulse generator start specified axis
number less than 3.
Set the manual pulse generator smoothing magnification
within the range of 0 to 59.
• Set the speed within the range of 0 to Speed limit value
control after change.
• Set the speed absolute value within the range of 0 to
Speed limit value after change.
• Set "command speed of program  override ratio" and
"speed change request  override ratio" within the
range of 0 to Speed limit value.
