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. Acknowledging the
FastStop is possible only if the operating voltage is back in its allowed range. Acknowledging can be done
either via the web interface or via the command interface by using the "Fast Stop Acknowledge" command.
Loss of gripper force following an error due to the voltage being too high or too low!
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 if there is no longer a high/low voltage error.
For the documentation of the system status word and the command to acknowledge the "Fast
Stop" via the command interface, see the "WSG Command Set Reference Manual".
