This down enable option provides outputs for control of the following solenoid valves on the
press brake.
•
High Speed Solenoids;
•
Filler Solenoids;
•
Decompression Solenoid;
•
Safety Solenoids;
•
Holding Solenoids and
•
Proportional Solenoids Enable.
The down enable condition from the down enable option is not physically connected to an
output, but is one of the conditions that must be met before down movement is allowed by
the PCSS. This condition used from the down enable option indicates that the down switch
has been pressed and that down movement of the pressing beam can occur due to the
required safety conditions being met.
The down low speed condition is enabled when slow speed operation is required, but as with
the down enable condition, it is not physically connected to an output. This condition is used
to indicate that slow speed down movement is enabled. Any of the following variables being
set, will cause a latched condition to be set which is not reset until the TDC input to the Kernel
Software interface is set:
•
Pressing speed;
•
Crawl speed;
•
CNC mute has been reached;
•
CNC controller has not yet been referenced;
•
Pressing of the material has begun; or
•
High speed disable distance before mute position has been reached.
When this latched condition and the down enable condition are both set, then the down low
speed condition will be enabled or set.
The outputs used on the PCSS for the solenoid valves on the press brake provided by this
option are detailed below with the connections shown in
operation of these solenoid valve outputs during up and down movement of the pressing
beam is shown in
