DBX132.5 Sensor S5 available (angular position of the motor shaft)
Edge evaluation: No
Signal state 1 Sensor S5 is available.
Signal state 0 Sensor S5 is not available.

DBX133.2 State value is generated, speed limitation p5043 is active
Edge evaluation: No
Signal state 1 The state value is generated and the speed limitations from drive parameter p5043 are active.
Signal state 0 The state value is not generated and the speed limitations from drive parameter p5043 are not active.
Note When generating the state value, the analog voltage values of sensor S1 are transformed into discrete
state values of drive parameter r5001.
Corresponding to ... DB31, ... DBX134 (clamped state)
Drive parameters: r5001
System variable: $VA_MOT_CLAMPING_STATE[<axis>]
OPI variables: vaMotClampingState

DBW134 Status of the clamping system (sensor S1)
Edge evaluation: No
Depending on the position of the clamping device, sensor S1 supplies an analog voltage value. To
simplify the evaluation of the clamped state, the analog voltage of sensor module SMI 24 is converted
into a state value.
The state values correspond to certain voltage ranges. The voltage ranges can be set via: Drive
parameter p5041[0...5].
Corresponding to ... DB31, ... DBW136 (analog value: clamped state)
Drive parameters: p5041[0...5], p5043[0...6]
