PCSS-A Series Technical Manual
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 are shown in
operation of these solenoid valve outputs during up and down movement of the pressing
beam is shown in
The proportional enable output is used to enable the proportional solenoid on the press brake
and is connected to a standard output. The proportional enable signal has a timer ON delay
configurable with I/O channel 31 of the ANO board for the Kernel Software Interface. This
ON timer is started by the down enable OR up OR decompression OR adjustment signals.
Once the pump is running, this output remains on whilst the down enable is on, the CNC
press controller has initiated the up command after decompression or during decompression.
The drive enable output is active while the proportional enable is on, but has a configurable
turn off delay with I/O channel 23 of the ANO board for the Kernel Software Interface.
The safety solenoid output is active whilst the down enable OR up signals are active. A turn
on delay can be set via ANO2 channel 20, and a turn off delay can be set via ANO channel
25 of the Kernel Software Interface. The turn off delay is only applied when the up command
is reset. Refer to
