Loss of gripping force on temperature error!
This error can only be acknowledged if there is no longer a temperature error.
The command to read out the current housing temperature and the command to acknowledge the
Fast Stop via the command interface are documented in the "WSG Command Set Reference Manu-
al".
9.12 Monitoring the drive current
The drive current is continuously measured and monitored during operation. An integrated motor model is
used to check whether the drive is being overloaded or not. In this case, the power output stage will be
switched off via a fast stop and a "current fault" will be displayed. The current error must be acknowledged.
This can either be done via the web interface or via the command interface using the "Fast Stop
Acknowledge" command. Current errors are recorded in the module's event log (see chapter 9.10).
Loss of gripping force when there is a current error!
This error can only be acknowledged if there is no longer a current error.
For the documentation of the command to acknowledge the "Fast Stop" via the command inter-
face, see the "WSG Command Set Reference Manual".
9.13 Monitoring the supply voltage
To ensure the correct functioning of the module, the supply voltage to its power section is continuously
monitored. If the measured voltage is outside a defined range, a warning or an error will be issued. The
following limits apply:
Threshold
Supply Voltage <= 20 V
Supply Voltage <= 22 V
Supply Voltage >= 26 V
Supply Voltage >= 28 V
Consequence
Low voltage fault
SF_POWER_FAULT will be set in the system's status word and the status indi-
cator will show the error state.
Low voltage warning
SF_POWER_WARNING will be set in the system's status word and the status
indicator will show the warning state.
Excess voltage warning
SF_POWER_WARNING will be set in the system's status word and the status
indicator will show the warning state.
Excess voltage error
SF_POWER_FAULT will be set in the system's status word and the indicator
