(2) Rewind ON (REWDS 1, 2) Outputs
With these outputs, the control informs that the part program is
being rewound. If the part program is rewound by RWD input
for an M02 or M30 command, RWDS 1 and RWDS2 are closed
during the rewinding operation.
NOTE
To use these outputs, set parameter RWDOUT (#6007 D4) to"1 ."
Otherwise, they are not provided.
19.2.33 DISPLAY RESET (DRSX, DRSZ) INPUTS
These inputs set the external 2-axis acurrent value display and the
current value display on the operator's panel CRT to "O." When
"DRSX' (X-axis display reset) or "DRSZ" (Z-axis display reset) is
closed, "O" is set to the external 2-axis current value display and the
current value display on the operator's panel CRT (the first screen
"EXTERNAL").
19.2.34 EXTERNAL STORE , MATCH, AND OUTPUT
(EIN, EVER, EOUT) INPUTS
These inputs are used to perform store, match, and output ope-
rations on the NC memory of the control from outside.
If these inputs are closed when the control is in the program edit
mode and Edit Output On (EDTS) output is closed, the following
operations take place:
EIN input is closed:
The part program is stored in the NC memory.
EVER input is closed:
The part program is matched against the NC memory.
EOUT is closed:
The contents of the NC memory are outputted.
While a store, match, or output operation is performed, the In-
Edit (EDTS) output is closed.
NOTE
The 1/0 equipment for the store and match operations depends on
setting IDVCEO, 1 and ODVCEO, 1 (#6003).
19.2.35 S4-DIGIT COMMANDS (DAS, SGS1 , GR1
THROUGH GR4, S! NV, AND SINVA) INPUTW
OUTPUTS
These signals are used to determine the speed of the spindle motor
when the control is in the state of S Command 4-Digit Analog
output.
GR1 through GR4 are used to enter into the control state of the
gear range between the spindle and the spindle motor to determine
the spindle motor speed by the spindle speed specified in the part
program.
SINV input inverts the polarity of the analog output at the time
of S Command 4-Digit Analog output.
While the polarity is inverted, SINVA signal is outputted.
(1) S4-digit Command Analog (GAS, SGS1) Output
Analog voltage (- 10V to OV to + 10V) is outputted as follows by
the spindle motor speed command and GR1 through GR4:
—.— ; The output when "GR1" input is closed. (Set the spindle
motor maximum speed at gear range "GR 1" to parameter
GRIREV: #627 1.)
—-- ; The output when "GR2" input is closed. (Set the spindle
motor maximum speed at gear range "GR2" to parameter
GR2REV: #6272.)
—--- ; The output when "GR3" input is closed. (Set the spindle
motor maximum speed at gear range "GR3" to parameter
GR3REV: #6273.)
----- ; The output when "GR4" input is closed. (Set the spindle
motor maximum speed at gear range "GR4° to parameter
GR4REV: #6274.)
