The
safety card
}
Activates safety functions
}
Monitors safe motion sequences.
}
Signals the status of safety functions to the safety control system
}
In the event of an error, activates the safe pulse disabler which is integrated within the
servo amplifier and shuts down the power to the motor
}
Passes the brake command to the servo amplifier that is executing the travel command
The
servo amplifier
}
Removes the power to the motor, if the safe pulse disabler is activated, switches the
motor to torque-free and can also control an internal motor brake.
The
safety control system
}
Activates the safety functions via inputs on the safety card
}
Evaluates signals from safety devices, such as:
–
E-STOP pushbuttons
–
Safety gates
–
Light beam devices
–
Two-hand buttons
}
Processes the safety card's status outputs
}
Safe interconnection between safety card and safety control system
}
Fault detection (short across contacts, short circuit) on signals between the safety con-
trol system and safety card, and initiation of measures
Configurator PASconfig SDrive
}
Configuration and parameterisation of the safety card
}
Safe upload and download of the configuration file
}
Online display of the status of the safety functions

Inputs and outputs
The safety card has safe inputs and outputs which
}
can be freely assigned
}
can be assigned fixed functions.
Inputs I0 to I6 can be used to activate the safety functions.
Outputs O0 to O3 can be used to acknowledge the status of the safety functions.
Inputs and outputs are assigned to the safety functions in the safety card's Configurator.
