ƒ BYPASS: Press off signal (Normally Open)
When active (on), all functions of the press controller are disabled and a BYPASS
signal is output, making it impossible to start the press.
If the signal becomes active during a press cycle, the press cycle is stopped.
ƒ NEAR ORIGIN: Near Home sensor signal (Normally Open)
Used in special applications on 10 ton and larger presses. It is only used when
performing a Home Position Search.
When the near origin sensor is used it must be enabled in System Parameter 00-36.
ƒ SELF CHECK OFF: Load Cell automatic check “OFF” signal
When this signal is “OFF” (or unconnected) at the time of inputting a START signal, the
home-position voltage level and CAL voltage level of the load cell is automatically
checked before the press cycle begins.
If the automatic check of the load cell is not required, turning “ON” this signal at the
time of inputting a START signal will cause this test not to be performed.
*Allow at least 10ms from the time this signal is turned on before turning on the START
signal. Do not turn this signal off at least until BUSY goes “HIGH”.
ƒ CLOCKWISE: Advanced Limit proximity signal (Normally Closed)
When the CW LIMIT signal is "OFF" or is not connected, it is not possible to move the
press in the advance direction. Only Home Position Search or Manual Jog operation in
the return direction is possible.
If a display unit is attached to the SAN Unit, the following will be displayed:
ƒ COUNTER-CLOCKWISE: Returned Limit proximity signal (Normally Closed)
When the CCW LIMIT signal is "OFF" or is not connected, it is not possible to move the
press in the return direction. Only Home Position Search or Manual Jog operation in
the advance direction is possible.
If a display unit is attached to the SAN Unit, the following will be displayed:
