B-63330EN/03 4.DESCRIPTION OF PARAMETERS
- 77 -
#1 PRO Specifies whether to enable override for rapid traverse, reference
position return, and positioning in the machine coordinate system in
axis control by PMC.
0: Disables override.
1: Enables override.
#2 POV Specifies the override signals that can be used for rapid traverse,
reference position return, and positioning in the machine coordinate
system in axis control by PMC.
0: ROV1 and ROV2, or RV0B to RV6B (signals for CNC axes)
1: ROV1E and ROV2E (signals for PMC axes only)
#7 NDI Specifies the behavior of PMC-based axis control when diameter
programming is used for the PMC controlled axis, as follows:
0: The actual amount of travel becomes twice the specified value,
but the feedrate remains as specified.
1: The actual amount of travel remains as is, but the feedrate
becomes half the specified value.
The parameter affects the amount of travel specified in the Rapid
traverse (00h) , Cutting feed (feed per minute) (01h) , Cutting feed
(sec/block specification) (02h) , Feed per revolution (12h) , Skip
(13h) , and External pulse synchronization (1Bh) commands.
It also affects the feedrate specified in the Cutting feed (feed per
minute ) (01h) , Feed per revolution (12h) , and Skip (13h)
commands. If parameter RPD (bit 2 of parameter No. 1409) = 1, the
feedrate specified in the Rapid traverse (00h) , Machine coordinate
system selection (06h) , and 1st. to 4th. reference position return (17h
to 1Ah) commands are also affected by this parameter, because the
rapid traverse rate is specified using the PMC signal. If parameter
RPD (bit 2 of parameter No. 1409) = 0, the actual feedrate is not
affected by this parameter, because it is set to the rapid traverse rate
specified in the corresponding parameter.
For the Cutting feed (sec/block specification) (02h) command, the
travel time remains unchanged from the value specified in command;
it is not affected by this parameter.
For the Machine coordinate system selection (06h) command, the
target position is not affected by this parameter. Instead, it is specified
in diameter, if bit 3 of parameter No. 1006 (specification by diameter)
= 1.
(Example) If the specified amount of travel is 100.000 mm and the
specified feedrate is 100 mm/min
