PCSS-F Additions Technical Manual
This down enable option provides outputs for control of the following devices on the press
brake:
• Mechanical Brakes and;
•
Electric Motor Quick Stop.
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 up enable condition is also controlled by this down enable option and although not
physically connected to an output, is one of the conditions that must be met before up
movement is allowed by the PCSS. This condition indicates that up movement of the pressing
beam can occur due to the required 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 down high speed condition is enabled when high 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 high speed down movement is enabled. The following conditions must be satisfied
for high speed down movement:
• Moving Down;
• Down Enable active and;
•
Down Low Speed is disabled.
