PMC Axis Control
2004.10.7
(7) Continuous feed ( 06h )
This command performs a continuous feed operation along a controlled axis in a certain
direction.
This command performs the same operation as continuous feed in the JOG mode of the
CNC.
Continuous feed is performed until a reset. At this time, the remaining amount of travel is 0
at all times.
By setting the reset signal ECLRg to 1, the command can be ended. At this time, the servo
motor is decelerated to a stop, the axis moving signal EGENg is set to 0, and the control
axis selection status signal *EAXSL is also set to 0.
Before specifying this command again, check that the control axis selection status signal
*EAXSL is set to 0.
Until the control axis selection status signal *EAXSL is set to 0, ensure that the reset signal
ECLRg continues to be set to 1.

Data
EC0g to EC6g G143.0 to .6 Continuous feed command (06h)
EIF0g to EIF15g G144,145 Continuous feedrate
EID31g G149.7 Feed direction (specified with
EID31g only)
Continuous feedrate
A feedrate along an axis is set in the same way as for cutting feed - feed per minute
(EC0g to EC6g: 01h). A feedrate change can be made during continuous feed.
If a feedrate (EIF0g to EIF15g) is set, and the logical state of the axis control
command read signal EBUFg is reversed, a new continuous feedrate is set.
This command is not buffered. So, the axis control command read completion
signal EBSYg need not be checked when this command is specified usually.
A set feedrate can be increased by a factor of 10 with bit 3 (F10) of
parameter No. 8002. Moreover, a set feedrate can be increased by a factor of up
to 200 with bit 2 (JFM) of parameter No. 8004.
CAUTION
A maximum feedrate applicable when override is applied differs from
a maximum feedrate applicable when override is canceled. Maximum
feedrate data in the two cases is indicated below.
