4.DESCRIPTION OF PARAMETERS B-63330EN/03
- 358 -
#6 EHF Specifies whether feed-forward control on the axial feed axis in
helical compensation is valid during cutting only or in the
synchronization mode based on G81.
0: Valid only during cutting.
1: Valid at all times in the synchronization mode based on G81.
Usually, set 0.
Feed-forward control is usually valid during cutting feed only. When
this parameter is set to 1, however, feed-forward control on the axial
feed axis in helical compensation is valid at all times during
synchronization based on the G81 command for a hobbing machine.
When bit 3 (RFW) of parameter No. 1800 is set to 1, feed-forward
control is valid, regardless of this parameter.
#7 #6 #5 #4 #3 #2 #1 #0
7712 FNR AMM PHD PHS
[Input type] Parameter input
[Data type] Bit
#0 PHS Specifies whether to perform acceleration/deceleration when EGB
synchronization is started or canceled if there is no R command in a
G81/G80 block.
0: Do not perform acceleration/deceleration when EGB
synchronization is started or canceled.
1: Perform acceleration/deceleration when EGB synchronization
when EGB synchronization is started or canceled, and
automatically perform phase alignment after acceleration when
synchronization starts.
#1 PHD Specifies the direction of movement for automatic phase alignment.
0: Positive (+) direction
1: Negative (-) direction
#4 AMM If M99 is issued from the main program:
0: The tape is rewound to execute the program again from the
beginning.
1: Alarm PS0018 is issued.
#5 FNR
In the fixture offset coordinate system rotation function,
coordinate system rotation is:
0: Performed.
1: Not performed.
#7 #6 #5 #4 #3 #2 #1 #0
7713 G5H HBF
[Input type] Parameter input
[Data type] Bit
#2 HBF Specifies whether to use the memory card interface on the CNC side
or PC side with the CNC screen display function of the open CNC.
0: Use the memory card interface on the CNC side.
1: Use the memory card interface on the PC side.
