User definable
additional
in-/outputs
All inputs on pins 10, 11, 12, 13 and 15 as well as the additional
outputs at pins 1, 14, 16 and 17 are free definable and assignable to
the desired signals. When the software is delivered above
mentionned signals are assigned.
5.1.2. Pinning of the SMC version:
SMC stepper motor cards are connected to the PC by a commonly
used printing cable. SMC cards have all three reference switches
connected to pin 11 and there are no additional standarized inputs
and outputs available.
Pinning LPT1
(SMC)
Pin assignment of the first LPT port as follows :
Pin 2 Data1 1+2 code of the current intensity phase A
Pin 3 Data2 11-no current 01-20% 10-60% 00-100%
Pin 4 Data3 dircection of current phase A
Pin 5 Data4 4+5 code of the current intensity phase B
Pin 6 Data5 11-no current 01-20% 10-60% 00-100%
Pin 7 Data6 direction of current phase B
Pin 8 Data7 7+8 code for motor X/Y/Z
Pin 9 Data8 00-X 10-Y 01-Z
Pin 1 Strobe adopting the signals
Pin 14 output coolant pump on/off (default)
Pin 16 output drilling spindle on/off (default)
Pin 17 output vacant
Pin 10 input vacant
Pin 11 input reference switch
Pin 12 input vacant
Pin 13 input vacant
Pin 15 input vacant
Pin 18-25 signal mass (0V GND)
Further technical information concerning controlling SMC cards can
be learned from documentation of the card. If the additional signals
or vacant inputs of LPT1 are to be used by the machine, they have to
be tapped directly on the cable.
