Technical terms:
1. Display portion for measuring load
Press controller has the following function: It is possible to select mode for measuring loads of press-fitting or crimping
using either peak value (initial setting value) or instantaneous value (measured at fixed point.)
1-1.Peak value (Initial setting) mode
When signal for ending measurement is input, measured peak value is compared with upper/lower limit comparison
value and judged. The load measuring mode display lamp “peak” blinks while measuring and lights up after
measuring.
1-2.Instantaneous value mode
When signal for ending measurement is input, then measured value is compared with upper/lower limit comparison
value and judged. The load measuring mode display lamp “instantaneous” blinks while measuring and lights up after
measuring.
2. Safety one process/die matching
2-1. Safety one process
This is a normal operation circuit. Press start signal should be continued to input until press hold is activated. If push
button is released before press hold activation, signal that is emitted to electromagnetic valve for driving ram is
released. After press hold is input, electromagnetic signal is output regardless of press start signal being ON or OFF.
Regarding electromagnetic valve signals, those for SV-1 are output (Connector pins Nos. 1 and 2 for electromagnetic
valve) simultaneously when press start is instructed and in addition, those for SV-2 are output (Connector pins Nos. 3
and 4 for electromagnetic valve) when press hold is input.
Press start signal should be released once when press upper limit signal is input. If press start signal is again input
when press upper limit signal is input, electromagnetic valve signal is output. When press start signal is continuously
input, only one process portion of electromagnetic valve signal is output and press will not restart.
2-2. Die matching
Control function for each mode will not work. Only load measurement function is operative. Only load value which
load-cell measures every moment is displayed. (Displayed value is not retained)
For press control circuit, only electromagnetic valve SV-1 (Connector Nos. 1 and 2 for electromagnetic valve) is
output when press start signal is input. If inching mechanism is installed on the press side, as electromagnetic valve
SV-1 works in every press start signal, it is possible for inching to operate.
