Error details and causes
The setting value of the detailed parameter 2
"Deceleration time 1" is outside the setting range.
[Operation status at error occurrence]
When the PLC READY signal [Y0] is turned from
OFF to ON: The READY signal [X0] is not turned ON.
At start: The system does not start.
During operation: The system stops with the setting
(deceleration stop/sudden stop) of the detailed
parameter 2 sudden stop selection (stop group 3). (Note
that the deceleration stop only occurs during the
manual pulse generator operation.)
The setting value of the detailed parameter 2
"Deceleration time 2" is outside the setting range.
[Operation status at error occurrence]
When the PLC READY signal [Y0] is turned from
OFF to ON: The READY signal [X0] is not turned ON.
At start: The system does not start.
During operation: The system stops with the setting
(deceleration stop/sudden stop) of the detailed
parameter 2 sudden stop selection (stop group 3). (Note
that the deceleration stop only occurs during the
manual pulse generator operation.)
The setting value of the detailed parameter 2
"Deceleration time 3" is outside the setting range.
[Operation status at error occurrence]
When the PLC READY signal [Y0] is turned from
OFF to ON: The READY signal [X0] is not turned ON.
At start: The system does not start.
During operation: The system stops with the setting
(deceleration stop/sudden stop) of the detailed
parameter 2 sudden stop selection (stop group 3). (Note
that the deceleration stop only occurs during the
manual pulse generator operation.)
The setting value of the detailed parameter 2 "[Pr.31]
JOG speed limit value" is outside the setting range.
[Operation status at error occurrence]
When the PLC READY signal [Y0] is turned from
OFF to ON: The READY signal [X0] is not turned ON.
At start: The system does not start.
The setting value of the detailed parameter 2 "[Pr.31]
JOG speed limit value" exceeds the "[Pr.8] Speed limit
value".
[Operation status at error occurrence]
When the PLC READY signal [Y0] is turned from
OFF to ON: The READY signal [X0] is not turned ON.
At start: The system does not start.
The setting value of the detailed parameter 2 "[Pr.31]
JOG speed limit value" is smaller than the "[Pr.7] Bias
speed at start".
[Operation status at error occurrence]
When the PLC READY signal [Y0] is turned from
OFF to ON: The READY signal [X0] is not turned ON.
At start: The system does not start.
The setting value of the detailed parameter 2 "Manual
pulse generator speed limit value" is outside the setting
range.
[Operation status at error occurrence]
At the power on or when the PLC READY signal [Y0] is
turned from OFF to ON: The READY signal [X0] is not
turned ON.
At start: The system does not operate.
Remedy
With the setting brought into the setting range, turn the
PLC READY signal [Y0] from OFF to ON.
With the setting brought into the setting range, turn the
PLC READY signal [Y0] from OFF to ON.
With the setting brought into the setting range, turn the
PLC READY signal [Y0] from OFF to ON.
When the PLC READY signal [Y0] is not turned ON
after the setting value is corrected, turn the PLC
READY signal [Y0] from OFF to ON.
When the PLC READY signal [Y0] is not turned ON
after the setting value is set to equal to or less than the
"[Pr.8] Speed limit value", turn the PLC READY signal
[Y0] from OFF to ON.
When the PLC READY signal [Y0] is not turned ON
after the setting value is set to equal to or more than
the "[Pr.7] Bias speed at start", turn the PLC READY
signal [Y0] from OFF to ON.
Correct the setting value and turn the PLC READY
signal [Y0] from OFF to ON.
