♦ Output Signals
Outputs are rated at +12~24VDC, 200ma. When activated, open collector sink outputs
(normally high) pull the input device low (0VDC).
ƒ SERVO ON: [OUT DATA0 - PIN #24] Servo Running Signal
Output when the servo is running. This signal will turn OFF when a reset is input.
May be used to monitor when to engage/disengage the maintenance brake (See
Section 4.14). When the Servo On signal is high (ON) the brake should disengage.
THE FOLLOWING OUTPUTS ARE ONLY AVAILABLE WHEN THE SAN UNIT IS CONFIGURED
FOR STAND ALONE OPERATION:
ƒ HOME SET: [OUT DATA1 - PIN #25] Home-position confirm signal
Output after a home-position search has been performed and a home position has
been defined.
*Home Position must be defined before Automatic operation will be allowed.
ƒ PRESS RETURNED: [OUT DATA2 - PIN #26] Return position stop signal
Output when the press is stopping between home-position (0mm position) and the
selected parameter [41: Job Start Position] when it is not in cycle.
If the selected parameter [41: Job Start Position] is set to 10mm, the signal is
output when it is stopping between 0 to 10.9mm.
*When using “Load Return” Operation Finish Mode, PRESS RETURNED is
output only when at home-position. (version 1.94 and higher)
Note that the press is not always resting at the home position (0mm).
Caution should be taken when selecting different Parameter numbers. If
the new parameter number selected does not have the same [41: Job Start
Position], the PRESS RETURNED signal may go low (OFF).
ƒ BUSY: [OUT DATA3 - PIN #27] Operating signal
When the press unit is in cycle, the signal is “ON”.
ƒ READY: [OUT DATA4 - PIN #28] Input Enable Signal
Output when the SAN Unit is capable of an input signal from external equipment,
such as a PLC.
READY output turns “OFF” in the following conditions:
o
During initial processing at powering up (for 5 seconds)
o
When in MANUAL mode
o
When an abnormal signal is output
o
When in Bypass status (when setting and during download communication).
o
While STOP signal is inactive
o
While in cycle, resetting and checking CAL
o
When operation of the press unit by an external input is impossible
o
On SAN4 Units - on loss of Drive Power
ƒ ABNORMAL: [OUT DATA5 - PIN #29] System Abnormal/Abnormal Result
Output when abnormalities are detected during a system check performed by the
unit or during a press cycle.
Output remains active until the reset signal is input.
ƒ ACCEPT: [OUT DATA6 - PIN #30] Press ACCEPT (OK) Signal
Output when the press result is within the press limits. This signal turns on just
before BUSY goes “LOW”.
Output remains active until the start or reset signal is input.
ƒ REJECT: [OUT DATA7 - PIN #31] Press REJECT (NG) Signal
Output when the press result exceeds the press limits. This signal turns on just
before BUSY goes “LOW”.
Output remains active until the start or reset signal is input.
