15. PMC CONTROL FUNCTION
1807
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.
(9) When a torque control command (EC0g to EC6g: 11h) is specified
Specify the torque data.
Specify a positive value when the torque is to be applied in the
positive direction. Specify a negative value when the torque is to be
applied in the negative direction.
The specified torque data can be changed in torque control mode by
setting the new data in the signal then inverting the logic of axis
control command read signal EBUFg.
Valid data range Units
–99999999 to +99999999 0.00001 Nm
NOTE
The data units will be 0.001 N when a linear motor is being
used.
[Classification] Input signal
[Function] Directs the CNC to read a block of command data for PMC axis control.
See “Basic procedure” for details of the operation performed when this
signal is set from “0” to “1” or from “1” to “0”.
