4 Explanation of Interface Signals
4.3 PLC Output Signals (Bit Type: Y***)
Cont. Signal name
A Handle pulse encoder communication connector priority
[Function] [Operation]
The priority of the handle input pulse is determined when the parameter "#1239 set11/bit1" is OFF.
0: Remote I/O connecting handle priority
1: Handle pulse encoder communication connector connecting handle priority
[Related signals]
(1) Handy terminal key 1 to 45 (X1CD0 to X1CFC)
(2) Handle/Incremental feed magnification code m (MP1, MP2, MP4: YC80, YC81, YC82)
(3) Handle/incremental feed magnification method selection (MPS: YC87)
(4) Handy terminal Data area top address (R297)
(5) Handy terminal Data valid number of registers (R298)
(6) Handy terminal Cause of communication error (R299)
(7) 1st handle/incremental feed magnification (R2508, 9)
Cont. Signal name
B PLC axis near point detection n-th axis
[Function]
The near point dog signal of the PLC axis reference position return is input.
[Operation]
Set the near point dog signal of the PLC axis reference position return for the following devices in the PLC.
Device No.
Y718 PCD1
Y719 PCD2
Y71A PCD3
Y71B PCD4
Y71C PCD5
Y71D PCD6
Y71E PCD7
Y71F PCD8
Note
(1) Setting the dog signal in the medium-speed processing of the PLC is less responsive than setting the dog signal in the
high-speed processing of the PLC.
Cont. Signal name
A PLC axis 1st to 3rd handle valid
[Function]
This signal is designated when handle feeds using 1st to 3rd handles are to be carried out with the PLC axis.
[Operation]
Designate with the following devices to carry out handle feed with the PLC axis.
Device No.
Y720 PCH1
Y721 PCH2
Y722 PCH3
Note
(1) When this signal is ON, each handle is dedicated to the PLC axis and is not valid for the NC control axis. The "n-th
handle axis selection code" (HSn1 to HSn16) and the "n-th handle valid" (HSnS) are used to select each handle axis.
(2) The handle feed magnification is common with that for the NC control axis.
Signal name
PLC axis near point detection 1st axis
PLC axis near point detection 2nd axis
PLC axis near point detection 3rd axis
PLC axis near point detection 4th axis
PLC axis near point detection 5th axis
PLC axis near point detection 6th axis
PLC axis near point detection 7th axis
PLC axis near point detection 8th axis
Signal name
PLC axis 1st handle valid
PLC axis 2nd handle valid
PLC axis 3rd handle valid
