1 Input and output signals
1.1 Introduction
All input and output signals are indicated with LED's on the front panel of the I/O modules.
When an input or output signal is active, the corresponding LED is on. There are three kinds of
signals: Y-axis signals, X-axis signals and general signals. In the next sections of this chapter
these input and output signals are explained.
There is a strong relation between the Y-axis signals. This relation has been laid down in the
timing diagram of the press cycle.
The timing diagram of the CNC-RDY signal has also been included. The numerical control
ready signal indicates that the active bend program can be executed. The CNC-RDY signal
depends on the status of start button, the position of the Y-axis and the position of the X-axis.
1.2 Y-axis input signals
Symbol Function
8
Opening command. This input must be active when the beam has to move in
the opening direction (Y-axis status 6).
9
Pressing command. This input must be active to move the press beam during
the pressing phase (Y-axis status 3). This input must also stay active during the
holding time (dwell time) at bend position and during decompression (Y-axis
status 4 and 5).
99
Fast closing command. This input must be active when the beam has to move
with high speed in the closing direction (Y-axis status 2).
Manual. This input must be active when the beam must be moved manually
with the handwheel. This is only possible when the control is in Manual mode
and the beam is below the mute position. When this input is active this is
displayed with the text 'adjust' in the lower right corner of the control screen.
= Parallelism switch input. See description of Y-axis machine parameter
'parallelism switch'.
