3. Relevant Process Data and Setpoints
3.1. Available Actual Values
Depending on the connected encoders and sensors, the monitor continuously measures and
updates the actual values shown in the list below. This means that every of these actual values
is available at any time for evaluation and can be combined with other functions to switch one
of the outputs ON or OFF.
Value/State Description Requirement
Standstill 1 Digital information (yes/no) for zero motion
of encoder 1 *) Incremental signal on
Encoder 1 input
Motion signal 1 Digital information (yes/no) for active
motion of encoder 1
Incremental signal on
Encoder 1 input
Speed 1 Actual speed of encoder 1 according to
customer scaling Incremental signal on
Encoder 1 input
Position 1 Actual position count of encoder 1
according to customer scaling **)
Quadrature encoder for
encoder input 1
Direction 1 Direction of motion (forward or reverse)
of encoder 1 Quadrature encoder for
encoder input 1
Standstill 2 Digital information (yes/no) for zero motion
of encoder 2 *) Incremental signal on
Encoder 2 input
Motion signal 2 Digital information (yes/no) for active
motion of encoder 2
Incremental signal on
Encoder 2 input
Speed 2 Actual speed of encoder 2 according to
customer scaling Incremental signal on
Encoder 2 input
Position 2 Actual position count of encoder 2
according to customer scaling **) Quadrature encoder for
encoder input 2
Direction 2 Direction of motion (forward or reverse)
of encoder 2
Quadrature encoder for
encoder input 2
Difference
Pos 1 - Pos 2 Differential position count between
encoder 1 and encoder 2, according to
customer scaling **) Quadrature encoders for both,
encoder 1 and encoder 2
*) Standstill can be defined by parameter setting
**) “Zero position” and “Zero difference” can be defined by individual RESET
