8.4.4.1 Traveled stroke(Actuator travel)
The measured travel of the last stroke in mm is output via index 4372 (0x1114)
Actuator travel [x10µm].
8.4.4.2 Cycle time
The duration of the last cycle in ms is output via index 4380 (0x111C) Cycle time [ms].
One cycle corresponds to 2 strokes: start position - stop position - start position.
The start position is in the direction of the sensor cable. The stop position is in the
direction of the top of the sensor head.
A lower and upper threshold for the cycle time in ms can be defined via index 4399
(0x112F), subindex 2 (0x02) Min. cycle time limit and subindex 3 (0x03) Max. cycle time
limit.
An alert is output via the process data when the value falls below the lower threshold or
exceeds the upper threshold via index 4400 (0x1130), subindex 2 (0x02) Min. cycle time
alert and subindex 3 (0x03) Max. cycle time alert.
8.4.4.3 Dwell time at start position and stop position (Dwell time [ms])
The dwell time in ms at the start position and at the stop position can be read via index
4381 (0x111D) Dwell time [ms], subindex 1 (0x01) Start position and subindex 2 (0x02)
Stop position. The start position is in the direction of the cable of the sensor and the stop
position is in the direction of the top of the sensor head.
8.4.4.4 Travel time of the piston during extension and retraction (Actuator travel time)
The duration of the last stroke in ms in the positive direction (extension of the pis‐
ton) can be read via index 4379 (0x111B) Actuator travel time [ms], subindex 1 (0x01)
Extend (positive direction). The duration of the last stroke in ms in the negative direction
(retraction of the piston) can be read via index 4379 (0x111B) Actuator travel time [ms],
subindex 2 (0x02) Retract (negative direction).
The positive direction goes in the direction of the sensor fixing screw. One stroke
corresponds to movement in a direction. Direction of movement during extension: Stop
position – start position. The start position is in the direction of the sensor cable. The
stop position is in the direction of the top of the sensor head.
