Error flag

This flag turns ON when an error occurs. At the same time, an error code is output to the "Error

code" register and is indicated on the 7-segment display on the front of this module.

• This flag turns OFF when the error state is canceled by power ON, initial start or the "Clear error"

relay.

Note, however, that the error reoccurs if the cause of the error still remains.

Present position display mode monitor

Indication of present position data is set to "Instruction value" or "Encoder input value" at the

"Switching of present position display mode" relay. This relay monitors which of the two modes the

display is in.

This relay is "0" when the mode is "Instruction value" and "1" when the mode is "Encoder input

value."

• Present position data is not displayed even if this input is set to "1" when the closed loop control

mode of parameter 2 (address B+0000) is set to "Disabled."

Interrupt output monitor

This indicates the state of interrupt outputs. 1: ON, 0: OFF

• This relay is enabled only when the general-purpose output of parameter 1 (address A+0076) is

set to "Interrupt output."

Driver communications completed

This input turns OFF when reading of the present position from the driver is started by the "Read

absolute present position" relay.

• This input turns OFF at power ON, initial start and start of the next read.

• This function is enabled only when "Absolute value control mode selection" at parameter 2: 020

is enabled.

Positioning completed signal

The states of external input signals for each axis are monitored and displayed as they are.

1: ON, 0: OFF

M outputs 0 to 7

The states of each M output are monitored and displayed. 1: ON, 0: OFF

M outputs are signals that are output when the present position is within the range set at "M output

range data" in the block data (block No.2).

Present position (10

) to Present position (sign 10

)

The present position data is displayed.

• The present position data display mode can be selected as "Instruction value" or "Encoder input

value" by the "Switching of present position display mode" relay.

Output code (01 to 99)

The output code set to the target step data (block data: block Nos.16 to 28) is output after

execution of the target step is completed in program operation.

• Output is enabled only in the program mode.

Step No. (01 to 99)

The step No. currently being executed in program operation is displayed.

• Output is enabled only in the program mode.

Error code (lower: 01 to 99), Error code (upper: 00 to 09)

This indicates the error code of the currently occurring error.

• The error code is also displayed on the 7-segment display at the same time.

• The indication returns to "00" when the error start is canceled by the "Clear error" relay.

Note, however, that the error reoccurs if the cause of the error still remains.

Block data No. monitor (00 to 31)

This indicates the block No. that was read during reading of the block data.

• The block No. is held until the next block data read.

Read data area for block transfer (PC

←←

← this module transfer buffer area)

This is the data storage area common to each axis for when block data is read. When the block

data of each axis is read from this module, it is read via this 64-byte area.
