(b) Signals indicating movement (MV1, MV2, MV3, ...)
[Classification]
Output signals
[Function] A signal indicating movement (moving signal) informs that the tool is moving along the corre-
sponding controlled axis.
A moving signal is provided for each controlled axis; a number appended to a signal name
represents a controlled axis number.

The tool is moving along the first axis.
The tool is moving along the second axis.
The tool is moving along the third axis.
[Output Condition]
A moving signal goes high when:
⋅ The tool starts moving along the corresponding axis.
⋅ Handle feed axis selection is performed for the corresponding axis in manual handle feed
mode
A moving signal goes low when:
⋅ The tool stops moving along the corresponding axis, and is placed in the effective area
NOTE These signals are output, regardless of whether automatic operation or manual operation is
performed.
(c) Signals indicating direction of movement (MD1, MD2, MD3, ...)
[Classification]
Output signals
[Function] A signal indicating direction of movement (moving direction signal) informs the moving direc-
tion along the corresponding controlled axis.
A moving direction signal is provided for each controlled axis; a number appended to a signal
name represents a controlled axis number.

The tool is moving along the first axis in the negative direction.
The tool is moving along the second axis in the negative direction.
The tool is moving along the third axis in negative direction.
[Output Condition]
A moving direction signal goes high when:
⋅ The tool starts moving along corresponding axis in the negative direction
A moving direction signal goes low when:
⋅ The tool starts moving along the corresponding axis in the positive direction
NOTE 1 These signals are output, regardless of whether automatic operation or manual operation is
performed.
NOTE 2 When the tool stops moving along an axis, the corresponding signal holds the previous state.
When the tool stops moving along an axis after moving in the negative direction, the
corresponding signal does not go low.
NOTE 3 In simultaneous automatic/manual operation, the direction is determined from the sum of the
move command values of both operations.
