7.13 Monitoring the supply voltage
To ensure the correct functioning of the product, the supply
voltage to its power section is continuously monitored. If this is
outside a defined range, a warning or an error will be issued. The
following limits apply:
Threshold
Consequence
V
DRIVE
<= 20 V
Low voltage fault
SF_POWER_FAULT will be set in the system's status word and the
status indicator will show the error state.
V
DRIVE
<= 22 V
Low voltage warning
SF_POWER_WARNING will be set in the system's status word and
the status indicator will show the warning state.
V
DRIVE
>= 26 V
Excess voltage warning
SF_POWER_WARNING will be set in the system's status word and
the status indicator will show the warning state.
V
DRIVE
>= 28 V
Excess voltage error
SF_POWER_FAULT will be set in the system's status word and the
status indicator will show the error state.
Hysteresis is used to prevent the states chattering to and fro. If
there is a voltage error, the power output stage will be switched
off using a fast stop and a voltage error will be indicated. This must
be acknowledged, but will only be possible when the operating
voltage is back in its permissible range. You can do this either via
the web interface or via the command interface via the "Fast Stop
Acknowledge" command.
WARNING
Loss of gripper power following an error due to the voltage
being too high or too low!
Workpieces can fall down and cause serious injury.
NOTE
• The low voltage fault will also be triggered if the power supply
is interrupted when switching the force off, e.g. via an
emergency stop relay.
• This error can only be acknowledged when there is no longer a
high/low voltage error.
• Futher information of the system status word and of the
command to acknowledge the "Fast Stop" via the command
interface, see the "WSG Command Set Reference Manual".
