DBW136 Analog measured value: Of the clamping system
Edge evaluation: No
Sensor S1 supplies an analog voltage value: 0 - 10 V. The analog value of the clamped state is
mapped to: 0 - 10000 increments, resolution 1 mV
Note
SIMATIC S7 input module: 0 - 27648 increments, resolution 0.36 mV
Adaptation factor if you change to a spindle with SMI 24: 2,7648
Corresponding to ... DB31, ... DBW134 (clamped state)
Drive parameters: p5041[0...5], p5043[0...6]
DB31, ...
DBX138.4 Sensor S4, piston end position
Edge evaluation: No
Signal state 1 The piston is in position, i.e. the piston is free to move
Signal state 0 The piston is not in position
Corresponding to ... DB31, ... DBX132.4 (Sensor S4 available)
