17.PMC CONTROL FUNCTION B-63943EN-1/02
- 1936 -
The simultaneous start mode on command (EC0g to EC6g: 41h)
enables multiple groups to start commands simultaneously. The
simultaneous start mode is set.
The simultaneous start mode off command (EC0g to EC6g: 40h)
cancels the mode in which multiple groups can start commands
simultaneously. The simultaneous start mode state is canceled.
Linear interpolation is enabled by specifying the cutting feed -
sec/block command (EC0g to EC6g: 21h) in the simultaneous start
mode after setting the feedrate-related parameters (rapid traverse rate,
acceleration/deceleration time constant, diameter/radius, linear
axis/rotation axis, etc.) in the same way.
Moreover, superimposition on a CNC command is possible.
Accordingly, PMC axis control enables oscillation cycle machining on
the cylindrical grinding machine.
NOTE
If an overtravel alarm or an alarm (PS0130, PS0138, or
PS0139) is issued with one of the simultaneous start
groups, the alarm signal EIALg for all simultaneous
start groups is set to 1, and a gradual stop occurs on
the controlled axis. To reset the alarm, set the reset
signal ECLRg for all simultaneous start groups to 1.

(To be specified using the 40 bits
consisting of the 16 bits of the axis
control feedrate signal (EIF) area

control data signal (EID) area.
Simultaneous start groups
Set groups to be started simultaneously.
Specify all groups to be started simultaneously, by setting the
corresponding bits to 1.
EIF0g = Group 1
EIF1g = Group 2
EIF2g = Group 3
EIF3g = Group 4
:
EIF15g = Group 16
EID0g = Group 17
