This FB links the input for the direction of rotation and the QSP function, and is safe against an open

circuit.

Function

 After mains connection and simultaneous TRUE at both inputs, the outputs are set as

follows:

Inputs Outputs

bCw_b bCCw_b bCwCCw_b bQSP_b

1 1 0 1

0 = FALSE

1 = TRUE

 The following truth−table results only if the inputs were set to TRUE once after power

switch−on

Inputs Outputs

bCw_b bCCw_b bCwCCw_b bQSP_b

0 0 0 1

1 0 1 0

0 1 1 0

1 1 unchanged unchanged

0 = FALSE

1 = TRUE

If you set both inputs to TRUE during operation, both outputs still have their previous output value.
