Chapter 6 Safety Functions
Signal Offset
The signal offset diagnostic confirms that a Sine/Cosine type encoder is
producing the proper offset on the Sine and Cosine signals. This diagnostic is
not performed when the feedback device type is configured as Hiperface.
describes the offset tolerance of the diagnostic. If the offset of the Sine
and or Cosine signals are outside the tolerance range, the safety feedback
instance reports a signal offset fault and the module is placed in the safe state.
Controller-based Safe
Monitor Functions
The Drive Safety instructions (see
) are available in the
Studio 5000 Logix Designer® application, version 31.00 or later, in the Drive
Safety instruction element group that is enabled when the Safety Program -
MainRoutine is open (see
).

Description
Safety Feedback Interface
SFX
The SFX function scales feedback position into position units and
feedback velocity into position units per time unit. SFX is used with other
Drive Safety instructions.SFX also provides unwind for rotary applications
and position homing.
Safe Stop 1
SS1
The SS1 function monitors the motor deceleration rate within set limits
during motor stopping and provides an indication to initiate Safe Torque
Off (STO) function when the motor speed is below the specified limit.
Safely-limited Speed
SLS
The SLS function prevents the motor from exceeding the specified speed
limit.
Safely-limited Position
SLP
The SLP function prevents the motor shaft from exceeding the specified
position limits.
Safe Direction
SDI
The SDI function prevents the motor shaft from moving in the unintended
direction.
Safe Brake Control
SBC
The SBC function provides safe output signals to control an external
brake.
