Error details and causes
The setting value of the detailed parameter 2 "Manual
pulse generator speed limit value" exceeds the "speed
limit value".
[Operation status at error occurrence]
At the power on or when the power supply is turned
from OFF to ON, or 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.
The setting value of the detailed parameter 2 "JOG
operation acceleration time selection" 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 "JOG
operation deceleration time selection" 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
"Acceleration/deceleration process selection" 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 "S-curve
ratio" 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 "Sudden
stop deceleration time" 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.)
Remedy
Set a value equal to or less than the speed limit value.
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.
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.
