DIGITAL ROBOT INTERFACE

5.1 Control functions

The control functions are bit fields (values) and single bits
(signals) in the I/O table. They are set by a robot and read
by the welding system.

5.1.1 WireFeedSpeed
This 16-bit function controls the wire feed speed during
welding. The value is given in scaled or non-scaled mode,
depending on the user setup.
In non-scaled mode:
• The minimum setup value is 10 (1.0 m/min).
• The maximum setup value is 250 (25.0 m/min).
• The minimum step is 1 (0.1 m/min).
In scaled mode:
250 0.1 m/min
• The minimum setup value is 0 (0.0 m/min).
480 0.1 V
With this value, the welding system limits the
100 0.1
minimum speed to 1.0 m/min.
89 1
• The maximum setup value is the
value, which is interpreted as 25.0 m/min.
• The minimum step is 1. The wire feed speed value
is calculated from the setup value by means of
the value scaling formula.
This value has an effect only when the
signal is set (1), and it overrides the corresponding memory
channel value. If the
wire feed speed from the active memory channel is used.

5.1.2 Voltage
This 16-bit function controls the welding voltage for the
MIG process. For other processes, the FineTuning
is used instead. The value is given in scaled or non-scaled
mode, depending on the user setup.
In non-scaled mode:
• The minimum setup value is 100 (10.0 V).
• The maximum setup value is 480 (48.0 V).
• The minimum step is 1 (0.1 V).
In scaled mode:
• The minimum setup value is 0 (0.0 V). With this
value, the welding system limits the minimum
voltage to 10.0 V.
• The maximum setup value is the
value, which is interpreted as 48.0 V.
• The minimum step is 1. The voltage is calculated
from the setup value by means of the value
scaling formula.
The value has an effect only when the
signal is set (1), and it overrides the corresponding memory
channel value. If the OnlineControl signal is cleared (0), the
value from the active memory channel is used.
