Questions answered in these manuals
What is the rated stroke of the SQX actuators?
The rated stroke is 20 mm.
How much drive force can the SQX series provide?
The actuators can deliver a drive force of 700 N.
How do I calibrate the travel of the actuator?
Connect the AC 24 V power, press the S3 button, the actuator moves to the 0 % position (LED flashes), then to 100 % (LED flashes) and stores the values in the micro‑processor.
