Digital Outputs
Definition Digital outputs are signals from the power source to the robot.
(1) Robot input
(2) Power source output
Heartbeat power
source (Heartbeat
power source) -
Single Bit
As soon as the interface creates an authenticated connection to the power source, this
signal changes its activity with a frequency of 1 Hz (1 second High, 1 second Low, 1
second High, etc.).
Additional information for TWIN systems:
As soon as the RI FB/i TWIN Controller establishes an authenticated connection to both
power sources, this signal changes its activity with a frequency of 1 Hz (1 second High, 1
second Low, 1 second High, etc.).
Power source
ready (Power
source ready) -
Single Bit
- The signal is High when the power source is ready to weld
- The signal is Low, if a fault occurs on the power source (Error) or a notification (Noti-
fication) is issued
- The signal can also be called a "common error", as it is set to Low for all types of
internal and external error
Additional information for TWIN systems:
The signal is only set to High when both power sources are ready to weld.
Warning (Warn-
ing) - Single Bit
- The signal is High when the power source issues a warning.
- The signal remains High until the reason for the warning has been rectified.
- The signal automatically changes to Low, as soon as the reason for the warning has
been eliminated
- The signal has no effect on the welding process or the operability of the power
source (welding can be started; running process is not interrupted, etc.)
Additional information for TWIN systems:
The signal is set to High as soon as one of the two power sources issues a warning.
