1A6AH Outside speed limit
value range
The setting value of the basic parameter 2 "[Pr.8] Speed
limit value" exceeds the command speed limit value.
[Operation status at error occurrence]
When the PLC READY signal [Y0] is turned from
OFF to ON: READY signal [X0] is not turned ON.
At start: The system does not operate.
After the speed limit value is set so as not to exceed
the command speed limit value, turn the PLC READY
signal [Y0] from OFF to ON.
1A6BH Outside acceleration
time 0 range
The setting value of the basic parameter 2 "Acceleration
time 0" is outside the setting range.
[Operation status at error occurrence]
When the PLC READY signal [Y0] is turned from OFF
to ON: READY signal [X0] is not turned ON.
At start: The system does not operate.
With the setting brought into the setting range, turn the
PLC READY signal [Y0] from OFF to ON.
1A6CH Outside deceleration
time 0 range
The setting value of the basic parameter 2
"Deceleration time 0" is outside the setting range.
[Operation status at error occurrence]
When the PLC READY signal [Y0] is turned from
OFF to ON: READY signal [X0] is not turned ON.
At start: The system does not operate.
With the setting brought into the setting range, turn the
PLC READY signal [Y0] from OFF to ON.
1AA0H Backlash
compensation
amount error
The calculation result of the following equation is
smaller than 0 or larger than 4194304.
[Operation status at error occurrence]
The READY signal [X0] is not turned ON.
"[Pr.2] Number of pulses per rotation (AP)", "[Pr.3]
Movement amount per rotation (AL)", "[Pr.4] Unit
magnification (AM)", "[Pr.11] Backlash compensation
amount"
Review the items above.
1AA1H Software stroke limit
upper limit
In the unit of "degree", the setting value of the detailed
parameter 1 "Software stroke limit upper limit value" is
outside the setting range.
[Operation status at error occurrence]
The READY signal [X0] is not turned ON.
Correct the setting value and turn the PLC READY
signal [Y0] from OFF to ON.
1AA2H Software stroke limit
upper limit
In a unit other than "degree", the software stroke limit
upper limit value is smaller than the setting value of the
software stroke limit lower limit value.
[Operation status at error occurrence]
The READY signal [X0] is not turned ON.
In a unit other than "degree", set so that the "[Pr.13]
Software stroke limit lower limit value" is smaller than
the "[Pr.12] Software stroke limit upper limit value" and
turn the PLC READY signal [Y0] from OFF to ON.
1AA3H Software stroke limit
lower limit
In the unit of "degree", the setting value of the detailed
parameter 1 "Software stroke limit lower limit value" is
outside the setting range.
[Operation status at error occurrence]
The READY signal [X0] is not turned ON.
Correct the setting value and turn the PLC READY
signal [Y0] from OFF to ON.
1AA4H Software stroke limit
lower limit
In a unit other than "degree", the software stroke limit
upper limit value is smaller than the setting value of the
software stroke limit lower limit value.
[Operation status at error occurrence]
The READY signal [X0] is not turned ON.
In a unit other than "degree", set so that the "[Pr.13]
Software stroke limit lower limit value" is smaller than
the "[Pr.12] Software stroke limit upper limit value" and
turn the PLC READY signal [Y0] from OFF to ON.
1AA5H Software stroke limit
selection
• The setting value of the detailed parameter 1
"Software stroke limit selection" is outside the setting
range.
• In the unit of "degree", "1: Apply software stroke limit
on machine feed value" is set.
[Operation status at error occurrence]
The READY signal [X0] is not turned ON.
• Bring the setting into the setting range.
• In the unit of "degree", set "0: Apply software stroke
limit on current feed value".
1AA6H Software stroke limit
valid/invalid setting
The setting value of the detailed parameter 1 "Software
stroke limit valid/invalid setting" is outside the setting
range.
[Operation status at error occurrence]
The READY signal [X0] is not turned ON.
With the setting brought into the setting range, turn the
PLC READY signal [Y0] from OFF to ON.
1AA7H Command in-
position width
The setting value of the detailed parameter 1
"Command in-position width" is outside the setting
range.
[Operation status at error occurrence]
The READY signal [X0] is not turned ON.
With the setting brought into the setting range, turn the
PLC READY signal [Y0] from OFF to ON.
