4 Explanation of Interface Signals
4.1 PLC Input Signals (Bit Type: X***)
Cont. Signal name
A In axis motion (+) n-th axis
[Function]
This signal indicates that the specified axial motion is in plus (+) direction.
These signals are for each control axis. The last number (n = 1, 2, 3...) of the signal abbreviation indicates the control axis
No.
[Operation]
The signal turns ON when the specified control axis starts moving in the plus direction or when it is moving.
The signal turns OFF when the specified control axis stops moving or when it moves in the minus direction.
An example of the timing chart for the jog mode is shown below.
Feed axis selection+ (+J1)
1st axis motion [+]
Feed axis selection- (-J1)
1st axis motion [-]
In axis plus motion (MVP1)
In axis minus motion (MVM1)
Note
(1) This signal operates regardless of the operation mode.
(2) The real movement direction is indicated.
(3) The signal does not turn ON during machine lock.
[Related signals]
(1) In axis minus motion n-th axis (MVM1 to 8: X7E0 to 7)
Cont. Signal name
A In axis motion (-) n-th axis
[Function]
This signal indicates that the control axis is moving in the minus direction
[Operation]
This motion direction is the reverse of the plus motion, and the operation is the same as "In axis motion (+)" signal
(MVPn).
