4 Explanation of Interface Signals
4.3 PLC Output Signals (Bit Type: Y***)
Cont. Signal name
A Display lock
[Function]
By using this signal, the current position displayed on the display unit can be prevented from being updated even if the
machine is moved by automatic operation or manual operation.
[Operation]
When the "Display lock" signal (DLK) is turned ON, the movement of the machine and the update of the program
coordinate system are performed as usual, but the current position display of the display unit remains locked.
Note
(1) This signal (DLK) is always valid and can be turned ON or OFF immediately.
(2) This signal is also valid during machine lock operation.

(1) In display lock (DLKN: XC29)
Cont. Signal name
A F1-digit speed change valid
[Function]
When this signal is ON and F1-digit feed is commanded, the feedrate registered in the parameters can be increased or
decreased by turning the manual handle.
[Operation]
<Enabling conditions of the speed change with the handle>
When the F1-digit command is valid, the feedrate can be increased or decreased by operating the first manual handle.
(The feedrate cannot be changed by the 2nd and 3rd handles.)
Changing the feedrate by the handle is available satisfying the following conditions:
 The operation must be in automatic start.
 The operation must be in cutting feed, and F1-digit feedrate command must be issued.
 The F1-digit feed parameter must be ON.
 The F1-digit feed switch must be ON.
 The operation must not be in handle mode.
 The operation must not be in dry run.
 Upper limit of F1-digit feedrate ("#1506 F1_FM") and F1-digit feedrate change constant ("#1507 F1_K F1") are not zero.
<Conversion of the F1-digit feedrate changing with handle operation>
Once the F1-digit feedrate is changed with manual handle, the changed feedrate is valid until parameter is changed or the
power is turned OFF. Changed feedrate can be checked only during the operation. However, if the parameter "#1246
set18/bit6" (Switch F1-digit feedrate change method) is set to "1", by changing the F1-digit feedrate parameter to the
changed feedrate, operation is kept at the changed feedrate even after the power is turned OFF. In this case, if the screen
is not switched, the changed parameter values are not reflected to the display.
The increase/decrease amount per handle gradient is expressed by the following formula.
ΔF = ΔP × (FM / K)
ΔP: Handle pulse (±)
FM: Upper limit of F1-digit feedrate (#1506 F1_FM)
K: F1-digit feedrate change constant (#1507 F1_K)
(Example) When the handle scale unit is to be made ±10 mm/min
Assuming that FM is 3600 mm/min, feedrate change constant (K) must be set "360" according to the following formula.
ΔF = 10 = 1 × (3600 / K)
