The operation and connections for this down enable option are the same as down enable
option 8, with the only difference being in the outputs provided. In this option an additional
output is provided for connection to a pressing valve to allow a higher than normal bending
speed when enabled.
The output connections used on the PCSS for the solenoid valves on the press brake
provided by this option are shown in
solenoid valve outputs during up and down movement of the pressing beam is shown in
Figure 11-29.
The pressing solenoid output is connected to a safety output on the PCSS and will be
switched on provided that:
•
The high speed pressing input from I/O channel 37 of the DO1 I/O for the Kernel
Software Interface is set; and
•
The clamping or pinch point of the material has been reached; or
•
The up command has been received from the CNC press controller after
decompression.
Should the soft stop operation be enabled as described in
valves will be delayed in switching off until down movement comes to a complete stop. The
proportional enable output will switch off immediately and can be used to perform a controlled
decelerated stop.
