Parameter
905
Rotation direction setting
error
■ Description
The set value of the basic parameter 1 "Rotation
direction setting" is outside the setting range.
■ Operation status at error occurrence
The LD75 READY signal (X0) does not turns ON.
■
Action
With the setting brought into the setting range,
turn the PLC READY signal [Y0] from OFF to ON.
■ Buffer memory address
Axis 1: 5
Axis 2: 155
Axis 3: 305
Axis 4: 455
■
Setting range
0, 1
906 Outside bias speed range
■ Description
• The set value of the basic parameter 1 "Bias
speed at start" is outside the setting range.
• The bias speed exceeds the speed limit.
■
Operation status at error occurrence
The LD75 READY signal (X0) does not turns ON.
■ Action
• Set the bias speed to not more than the speed
limit value.
• With the setting brought into the setting range,
turn the PLC READY signal [Y0] from OFF to
ON.

908
Use prohibited area write
error
■ Description
Any value other than 0 was set at buffer memory
address 101, 251, 401, 551 (use prohibited area).
■
Operation status at error occurrence
LD75 READY signal (X0) does not turn on.
■ Action
• With the setting value being 0, turn on PLC
READY signal [Y0].
• Review the program which sets a value at
buffer memory address 101, 251, 401, 551 (use
prohibited area).
910
Outside speed limit value
range
■
Description
The set value of the basic parameter 2 "Speed limit
value" is outside the setting range.
• The value obtained by the conversion of the
speed limit value with respect to the frequency
exceeds the maximum output frequency of the
unit.
• The speed limit value is smaller than the OPR
speed.
■ Operation status at error occurrence
When the power is turned ON or PLC READY
signal (Y0) is turned from OFF to ON: LD75 READY
signal (X0) is not turned ON.
At start: The system will not operate.
■
Action
The value converted into the frequency should
not exceed the maximum output frequency of the
module.
LD75P
 : 200000 [pulse/s]
LD75D  : 4000000 [pulse/s]
• Set a value which is not less than the OPR
speed.
• With the setting brought into the setting range,
turn the PLC READY signal [Y0] from OFF to
ON.

Outside acceleration time
0 range
■
Description
The set value of the basic parameter 2
"Acceleration time 0" is outside the setting range.
■ Operation status at error occurrence
When the power is turned ON or PLC READY
signal (Y0) is turned from OFF to ON: LD75 READY
signal (X0) is not turned ON.
At start: The system will not operate.
■ Action
With the setting brought into the setting range,
turn the PLC READY signal [Y0] from OFF to ON.
