Error description Causes and actions
data error
The data of the tracking encoder is abnormal.
(The amount of the change is 1.9 times or more.)
[Actions]
1) Check the conveyor rotates at the fixed velocity.
2) Check the connection of the encoder.
3) Check the earth of the earth wire.
reverses
Tracking parameter[EXCRGMN] and [EXCRGMX] Setting value
reverses
[Actions]
1) Check the value of [ENCRGMX] and [ENCRGMN] parameters.
range over
The set value is outside the range parameter [TRBUF]. The first
argument is 1 to 8, and the second argument is 1 to 64.
[Actions]
1) Check the value of [TRBUF] parameter.
where data is written
The data of the size or more of the buffer in which the TrWrt command
was continuously set to the second argument of parameter [TRBUF]
was written.
[Actions]
1) Check the execution count of the TrWrt command is correct.
2) Check the value of the second argument of parameter [TRBUF] is
correct.
3) Check that the X and Y coordinates of the position variable ”PCHK”
in “CM1” program are not ”0.” If they are ”0,” change the difference
from the theoretical value to an allowable value.
The TrRd command was executed in state the data is not written in
tracking buffer.
[Actions]
1) Execute the TrRd command after confirming whether the buffer has
the data with the state variable [M_Trbfct].
2) Confirm whether the buffer number specified by the buffer number
specified in TrWrt Mende and the TrRd command is in agreement.
Tracking
The value set as the parameter [EXTENC] is outside the range. The
ranges are 1-8.
[Actions]
Please confirm the value set to Parameter [EXTENC].
Please confirm whether the Q173DPX unit is installed in the slot
specified for parameter "ENCUNITn" (n=1-3).
Please confirm whether slot 0-2 of a basic base is not specified by
setting the parameter.
Please confirm whether the setting of "Management CPU" that exists in
"I/O unit and intelligent function unit details setting" of the parameter of
the sequencer and specification of parameter "ENCUNITn" (n=1-3) are
corresponding. There is a possibility Q173DPX is not robot CPU
Q173DPX is installed in slot 0-2 of a basic base.
[Actions]
Slot 0-2 of the basic base is basically only for CPU. Please install
