15. PMC CONTROL FUNCTION
511
Axis control
command
(hexadecimal
code)
Operation
Speed command (linear acceleration/deceleration)
Performs continuous feed at the specified speed.
Torque control
Continuous feed under torque control
Auxiliary function
12h
Performs the same function as the miscellaneous function
(M function), used by the CNC.
Machine coordinate system selection
Performs the same operation as G53, used by the CNC.
When using the rapid traverse command (EC0g to EC6g: 00h), the
feedrate can be specified in either the same parameter as that used by the
CNC (No. 1420) or the PMC’s axis interface feedrate signals EIF0g to
EIF15g. This can be set with RPD, bit 0 of parameter No. 8002.
The reference position return command (EC0g to EC6g: 05h) enables the
following operation: When DLZ, bit 1 of parameter No. 1002, specifying
reference position return without dogs for all axes, or DLZx, bit 1 of
parameter No. 1005, specifying reference position return without dogs for
each axis, is valid and the tool has not been returned to the reference
position since the power was turned on, move each axis in the direction
specified by the continuous feed command (EC0g to EC6g: 06h)
(position the tool to a point near the reference position) and issue the
reference position return command (EC0g to EC6g: 05h). This returns
the tool to the reference position (positions the tool to the grid nearest the
current position) without using the deceleration signal for reference
position return.
Note that, when positioning the tool to a point near the reference position,
the tool must be moved in the direction of reference position return at such
a speed that the servo position error exceeds the value of parameter No.
1836.
The direction of the grid relative to the proximate position depends on
ZMIx, bit 5 of parameter No. 1006.
After the reference position has been established, reference position
return can be performed at high speed by issuing the reference position
return command (EC0g to EC6g: 05h), irrespective of the reference
position return direction specified by ZMIx, bit 5 of parameter No. 1006.
