1 Introduction
The Safe Torque Off (STO) safety function can be realized with devices from the 5th generation of STOBER
inverters.
There are two switchoff distances available:
The enable function of the drive controller is used for the first switch-off distance. The diagnostics can be
performed via the binary output or a fieldbus system.
For the second switchoff distance, the ASP 5001 option is used. If the safety function is required, the controller
of the power unit is switched off via the switching elements of a safety relay and the positively-driven signal
contact is switched at the external safety circuit (NC contact).
The start-up of the motor is then also prevented when faults in the region of the power unit or the control circuit
are present as the required rotating magnetic field is no longer generated.
Advantages of the start inhibitor:
•
No switching of the supply voltage required
• Faster restart possible
• Lower contact wear
• Simplified wiring
The following tables shows which inverter the ASP 5001 certified accessory is available for:
With ASP 5001, applications can be realized up to a maximum:
•
PL e in category 3 to DIN EN ISO 13849-1:2008-12 or
• SIL 3 to DIN EN 61800-5-2:2008-04.
