19.2.22 MACHINE-READY (MRD) INPUT
This input informs that the external heavy-current circuit is ready.
When MRD input is closed after closing of Servo Power Input/
Output (SVMX) from the power-on/off unit of the control after the
power is turned on, the control is ready and “RDY” is displayed on
the CRT screen.
When MRD input is opened with the control being ready, the
control is put in the alarm state alarm code “280” is displayed),
thereby stopping the operation.
For the turning of power sequence, refer to” 10 CONNECTION
OF INPUT SEQUENCE”
19.2.23 EMERGENCY STOP ON (xESPS) OUTPUT
When Emergency-Stop Input (X TESP) is opend, *ESPS output is
opend.
19.2.24 EXTERNAL RESET (ERS) INPUT AND RESET
ON (RST1 ,2) OUTPUT
ERS is the input to reset the control. When ERS input is closed, the
control stops all of its operations, closing Reset On outputs RST1
and RST2 for one second. The output signals are opened except for
the following,

Output
at ERS Input Closed
Previous conditions kept.
Output contact is closed for one second while
ERST input contact is closed or is opened.
Contactor kept closed unless alarm causing
factor is removed.
Previous conditions kept.
Contact closed if any of selected, group of tools
reaches end of life.
Previous conditions keut.
When ERS input is closed, the control is put in the label skip state.
However, memory is rewound, while the tape is not.
19.2.25
INTERLOCK (STLK) INPUT
This input stops the spindle travel in the atuomatic operation mode.
When “STLK” input is closed during the spindle travel in the
automatic operation mode, only the spindle travel is stopped with
the automatic operation being activated (“STL’> output is in the
closed state). When “STLK” input is opened again, the spindle
travel is resumed.
“STLK’ input does not affect the M, S, and T comannds in both
manual and automatic operation modes.
19.2.26 AMARM (ALM) AND INPUT ERROR (IER)
OUTPUTS AND EXTERNAL ERROR DETECT
(ERRO,l) INPUTS
(1) Akirrn (ALM) and Input Error (IER) Outputs
These outputs inform that the control is in the alarm state.
IER: This output is closed on detection of an alarm caused by
the information from the part program or the input device.
(Alarm codes “010” through “129.”)
ALM: This output is closed on detection of any alarm other than the
avobe. (However, the alarm for the fault of the logic circuitry in
the control is not inchrded.)
These outputs are opened again when the cause of the detected
alarm has been removed and RESET operation is performed.
(2) External Error Detect (ERRO, ERR I) Inputs
These inputs put the control in the alarm state from the outside.
ERRO: When this input is closed, the control displays alarm
code “180” and is put in the alarm state. If this input is closed
during the execution of the part program in the automatic
operation mode, the execution is stopped on completion of the
block being executed.
ERR1: When this input is closed, the control dkplays alarm code
“400” and is put in the alarm state. If this input is closed during the
extention of the part program in the automatic operation mode, the
tool travel is immediately slowed down and stopped.
19.2.27 RAPID THREADING PULL-OUT (CDZ)
INPUT AND ERROR DETECT-ON (SMZ) INPUT
(1) Rapid Threading Pull-out (CDZ) Input
This input determines whether rapid threading pull-out is
performed or not in the exection of G92 (thread cutting cycle) or
G76 (composite thread cutting cycle). When CDZ input is
closed, the rapid threading pull-out is performed; when this input
is open, it is not performed.
The control determines by the CDZ input whether rapid
threading pull-out is performed or not at the start of a thread cutting
cycle. To open/close CDZ input by such a command as M, add the
delay time of the input circuit processing and set the state of CDZ
input to the start of thread cutting cycle.
