Features
This enables the analog welding function. It enters the connection and environment information of the available welding machine’s analog I/O and digital signal output as input factors.
The target welding machine must support an analog interface so it can receive target current and target voltage inputs from the analog output channel of the connected controller. Set the channel number (1 or 2) and output mode (current/voltage) of the physically connected analog channel in ch_v_out and ch_f_out. The analog input/output range of the controller is 0-10 V for voltage mode and 4-20 mA for current mode. Make sure to set the mode and output range of each channel to be compatible with the input specification and range of the welding machine. For example, if the target input range of the welding machine is 0-10 V, it is ideal to set the output channel of the controller as voltage mode (0-10 V output range). Another example would be if the input channel specification of the welding machine is 2-15 V. In this case, set the analog channel current mode (4-20 mA output range) on the corresponding controller and connect a 75 ohm resistance to output a 3-15 V voltage. (In this case, the 2-3 V range, which cannot be set using the controller, cannot set a target.) It is recommended that the welding machine be set with as large an input range as possible.
Set the maximum and minimum range of the controller analog output in spec_v_out and spec_f_out.
First item of spec_v_out/spec_f_out = WO_min Second item of spec_v_out/spec_f_out = CO_min Third item of spec_v_out/spec_f_out = WO_max Fourth item of spec_v_out/spec_f_out = CO_max |
Where, WO_min and WO_max are the minimum and maximum output of the welder, and CO_min and CO_max are the controller analog output corresponding to WO_min and WO_max.
Note
The welding current varies according to the wire feeding speed, basic material, material/type/stick-out of the welding wire, and welding voltage, and this must be monitored with the welding machine or a separate current sensor.
In order to monitor the voltage/current measurements during welding, it is necessary to connect an analog output welding machine or a separate sensor. Set the analog input channel number and input mode of the corresponding controller in ch_v_in and ch_c_in.
Set the maximum and minimum input range of sensor measured in spec_v_in and spec_f_in.
First item of spec_v_in/spec_c_in = SO_min Second item of spec_v_in/spec_c_in = CI_min Third item of spec_v_in/spec_c_in = SO_max Fourth item of spec_v_in/spec_c_in = CI_max |
Where, SO_min and SO_max are the minimum and maximum sensor, and CI_min and CI_max are the controller input corresponding to SO_min and SO_max.
Set the channel numbers for ARC-ON/OFF (gas output signal - start/end), GAS-ON/OFF (gas output signal - start/end), INCHING-Forward-ON/OFF (forward wire feed signal - start/end), INCHING-Backward-ON/OFF (backward wire feed signal - start/end), and BlowOut-ON/OFF (torch cleaning gas output signal - start/end), which connect to the welding machine using digital contact method. In the case of signal outputs other than the ARC-ON/OFF signal, enter them selectively, depending on whether the welding machine supports the corresponding function.
