Chapter 6: System Operation
ƒ Return
After both an ACCEPT or REJECT judgment the load will be released, then the press
will move to the position set in [41: Job Start Position].
ƒ [ACCEPT] Return, [REJECT] No Return
When the judgment is an ACCEPT, the press will move to the position set in
[41: Job Start Position].
When the judgment is a REJECT, the press will stop and the load will be released.
ƒ [ACCEPT] No Return, [REJECT] Return
When the judgment is an ACCEPT, the press will stop and the load will be released.
When the judgment is a REJECT, the press will move to the position set in [41: Job
Start Position].
ƒ Jog Return
During the Return Operation, if the START signal is turned OFF, the operation will stop
and if it is turned ON, the operation will start from the position where the press ram
stopped. If a load exist at the stop point it will be released.
ƒ Keep Load
When the judgment is an ACCEPT, the operation will stop at the target load or distance
position without the load being released.
When the judgment is a HIGH REJECT, the load will be released to near zero and stop.
When the judgment is a LOW REJECT, the operation will stop at the point of reject.
This Mode is very useful when used in “Step Press” operations. See “Step Press
Operation” on page 6-46 for explanation and setup.
ƒ Load Ignore Return
After both an ACCEPT or REJECT judgment, the press will ignore any load built up in
the cylinder and return to the position set in [41: Job Start Position].
When the system is returning the cylinder in normal operation, any load will
be released before returning to [41: Job Start Position]. If the cylinder reaches
[41: Job Start Position] and it still has load, it will pass the [41: Job Start
Position] and go to the Press Home Position (zero position).
This Return Method ignores the cylinder load while returning.
ƒ No Return
After both an ACCEPT or REJECT judgment, the press will stop and the load will be
released.
In No return mode, when a load is being detected, the releasing operation of
the load is done until the load is almost zero, but the press will not return to
the operation finish return position.
If you want to stop the operation with the press on the target position without
releasing the load, select the Keep Load Operation.
ƒ Load Return (software version 1.94 and later)
After both an ACCEPT or REJECT judgment, the press will decompress the load at
[75: Decompression Speed] until the load has dropped below the value set in [21:
Return Load].
On “P-type” presses this “decompression” is limited to 20 seconds.
On “F-type” presses this “decompression” is limited to approximately 1 second due to
the load holding limitation.
If decompressing with an excessive load acting against the ram increase [75:
Decompression Speed], otherwise an Abnormal 9-7 may occur. If the load is
being decompressed too fast decrease [75: Decompression Speed].
If, after reaching the target, the load sensed is less than the value
programmed in [21: Return Load], the press will stop at the target position.
