15. PMC CONTROL FUNCTION
893
(5) Dwell (EC0g to EC6g: 04h)
For this command, the signals are used to specify, in binary format,
the dwell time.
Data range Unit
1 to 9999999 ms
When diameter programming is specified with bit 3 (DIAx) of
parameter No. 1006, bit 1 (CDI) of parameter No. 8005 can be used
to specify whether a radius or diameter is to be used in a command.
NOTE
When the increment system IS–C is used, the least input
increment for the dwell time can be set to 0.1 ms, according
to the setting of bit 1 (DWE) of parameter No. 8002.
(6) Continuous feed (EC0g to EC6g: 06h)
For this command, signal EID31g is used to specify the direction of
continuous feed, as follows:
0: Positive direction
1: Negative direction
Signals EID0g to EID30g are undefined.
(7) Auxiliary functions (EC0g to EC6g: 12h)
Auxiliary functions 2 (EC0g to EC6g: 14h)
Auxiliary functions 3 (EC0g to EC6g: 15h)
For this command, the signals are used to specify, in binary format,
an auxiliary function code to be sent to the PMC. The auxiliary
function code can be specified using either one or two bytes,
depending on the setting of bit 6 (AUX) of parameter No. 8001, in
signals EID0g to EID15g.
(8) Machine coordinate system selection (EC0g to EC6g: 20h)
For this command, the signals are used to specify, in binary format,
an absolute machine coordinate, according to the increment system
used by the axis.
Example: For absolute value “10000”
Input increment inch 1.0000 mm 10.000
Output increment mm 25.400 inch 0.3937
The direction of rotation can be specified about a rotation axis with
a parameter. To enable the roll–over function, set bit 0 (ROAx) of
parameter No. 1008 to 1. Then, select whether the tool is to be
rotated in the direction corresponding to the sign of the specified
value, or in whichever direction minimizes the distance to the end
point, using bit 1 (RABx) of parameter No. 1008. The moving
distance per rotation must be set in parameter No. 1260.
