4 Explanation of Interface Signals
4.1 PLC Input Signals (Bit Type: X***)
Cont. Signal name
A Power OFF required after parameter change
[Function]
This signal informs that the set parameter is not valid unless the power is turned OFF and ON.
[Operation]
When the following operation is executed, the "Power OFF required after parameter change" signal is output, and the
display symbol "PR" is displayed in the operation status section.
 When you set the parameters or input data to them that become valid after the power is turned OFF and ON.
 When you set the auxiliary axis parameters or input data to them that become valid after the power is turned OFF and
ON.
 The maintenance data for the ALL1 is input.
 The backup data is input with the SRAM backup function.
When the power is turned OFF and ON, the "Power OFF required after parameter change" signal turns OFF, and the "PR"
display disappears.
Note
(1) Even if the same value is set to the parameter which requires the power OFF and ON, the "Power OFF required
parameter change" signal is output, and the "PR" is displayed.
(2) Even if the value is returned to the original value after setting the parameter which requires the power OFF and ON,
the "Power OFF required after parameter change" signal remains ON, and the "PR" also remains displayed.
(3) When the parameters with DDB or G10 are rewritten, the "Power OFF required after parameter change" signal is not
output, and the "PR" is not displayed. Because they do not require the power OFF and ON.
Cont. Signal name
A Thread, tap block stopping in manual arbitrary reverse run
[Function]
This signal notifies the PLC that a block stop occurred before moving to thread cutting or tapping during the manual
arbitrary reverse run.
[Operation]
When the "Actual cutting mode (thread, tap) in manual arbitrary reverse run" signal (MRCMD) is ON, a block stop occurs
before moving to thread cutting and tapping.
This signal turns ON when this block stop occurs.
If cycle start is executed in this state, thread cutting and tapping start and this signal turns OFF.
