Error details and causes
Code 1 is set for the step start information when the step
is outside standby.
[Operation status at warning occurrence]
The step will not start.
The detailed parameter 2 "External command function
selection" setting range is exceeded.
[Operation status at warning occurrence]
Even if the external command signal is turned ON, the
system will not perform anything.
The movement amount is not large enough for
automatic deceleration.
[Operation status at warning occurrence]
The system stops immediately after it reaches the
positioning address.
The positioning data No. is set outside the setting range.
[Operation status at warning occurrence]
Teaching is not carried out when the setting value is 0 or
601 or more.
(The setting value is automatically reset to "0" by the
Simple Motion module even when a "0" or "601" or more
is set.)
The teaching data selection set value is outside the
setting range.
[Operation status at warning occurrence]
Teaching is not carried out.
• A target position change request was given for the
control method other than ABS1 and INC1.
• A target position change request was given during
speed control mode, torque control mode or
continuous operation to torque control mode.
[Operation status at warning occurrence]
The target position change is not carried out.
A target position change request is turned ON during
continuous path control.
[Operation status at warning occurrence]
The target position change is not carried out.
A target position change request was given during
deceleration to a stop.
[Operation status at warning occurrence]
The target position change is not carried out.
A target position change request was issued when
speed change 0 flag ([Md.31] Status: b10) was ON.
[Operation status at warning occurrence]
The target position change is not carried out.
"[Cd.27] Target position change value (New address)" is
outside the software stroke limit range (+).
[Operation status at warning occurrence]
The target position change is not carried out.
"[Cd.27] Target position change value (New address)" is
outside the software stroke limit range (-).
[Operation status at warning occurrence]
The target position change is not carried out.
"[Cd.27] Target position change value (New address)" is
out of range (0 to 359.99999 [degree]).
[Operation status at warning occurrence]
The target position change is not carried out.
• A value exceeding "[Pr.17] Torque limit setting value"
is set to "[Cd.143] Command torque at torque control
mode" at torque control mode.
• A value exceeding "[Pr.17] Torque limit setting value"
is set to "[Cd.150] Target torque at continuous
operation to torque control mode" at continuous
operation to torque control mode.
[Operation status at warning occurrence]
The torque is controlled with the torque limit setting
value.
Remedy
Do not set a "1" to the step start information when the
step is not in standby state.
Set the detailed parameter 2 "External command
function selection" to within the setting range.
Set a decelerating address or a movement amount to
the positioning data.
Set the positioning data No. to within the setting range.
Set the teaching data selection set value to within the
setting range.
Do not turn ON the target position change request in
the following cases.
• A control method other than ABS1 and INC1 is used.
• During speed control mode
Do not turn ON the target position change request
when an operating pattern "continuous path control" is
used.
Do not turn ON the target position change request
during deceleration stop.
Do not turn ON the target position change request
when speed change 0 flag ([Md.31] Status: b10) is ON.
Correct the setting value.
Correct the setting value.
Correct the setting value.
Review the setting value so that the setting torque is
not exceeded the torque limit setting value.
