5.6.6
Reset steps
In RUN mode, using this input, you can reset the count of steps, and quit the alarm,
switching off the output "END STEPS" related to the selected program. That affects the
pairs of electrodes that did generate the alarm.
5.7.
Control outputs
5.7.1
Main Solenoid valves
(EV 1,2,3,4)
Outputs are active at +24VP with load current up to 200mA, protected against short circuits,
used for driving the pistons closing the electrodes.
Outlets can be independently associated with pre squeeze piston or with squeeze piston.
The association can be done in edit menu by mean of a program parameter.
In Seam mode the valves are associated to squeeze piston and roller motor drive.
5.7.2
Forge solenoid valves and roll motor
(EV 5)
This active output to +24 VP with load current up to 200mA, protected from short circuit.
In spot mode, this output is activated during forging phase.
In Seam mode, this output is used to drive the roll motor
5.7.3
Pre stroke solenoid valve
(EV 6 PRE-STROKE)
This active output to +24VP, with load current up to 200mA, protected from short circuit., is
activated or deactivated as described in 5.3
5.7.4
Proportional valve
This output "analog" is able to provide a DC voltage variable from 0V (0%) to 9.9V (99%) in
the case of full scale at 10V.
Using a scale parameter in the menu system parameters, you can set the output voltage up
to 99%, from 5 to 10V.
In spot mode the output is set to the value entered in the running program for each program
parameters setting.
In Seam mode, the value is kept constant throughout the program running, until the
program changes.
5.8.
Signalling outputs
There are seven signals outputs described below.
5.8.1
Ready
This active output to +24VP, with load current up to 200mA, protected from short circuit.
When active indicates the inverter is ready to execute the machine cycle (RUN).
It is turned off in case of errors or alarms, or when the key is in edit position.
