Teach process The teaching functionality will be disabled minutes after encoder power. Time begins to start anew after each teaching operation.. Set input on HIGH for seconds. DV/ status output reflects the reverted input and will start oscillating after seconds. Now set input on LOW.. Get encoder in position intended for voltage output / current.. Set input on HIGH for second. DV/ status output will switch to LOW for seconds and then start oscillating.. Get encoder in position intended for voltage output / current.. Set input on HIGH for one second. DV/Status output will switch to HIGH for seconds and then shortly oscillate to signal that the teaching operation has been completed. In the event of one out of both taught limits being beyond the sensing range or too close to each other, the DV/status output will oscillate shortly. There is no teaching of sensing range. The operation must be repeated under consideration of minimum teaching limit and sensing range. Set / restore default Set input on HIGH for seconds. (After seconds, the DV/status output will start oscillating while restoring default in second ). Note: Current position will be the new zero point.
