Data output (NG/OK/NG signal, NPN open collector), Remote control (hold-preset, preset-recall, zero-set), Origin- set/Preset, Zeroset, GO/NG judgment, Max/Min/Runout value holding, Counting direction switching, Power ON/OFF, inch/mm conversion (on inch/metric models only) Alarms... Low voltage, Counting value composition error, Over-flow error, Tolerance limit setting error Features include... With the max./min. value holding function, the signal ID-C can output the signal of the GO/NG judgment result against the peak values set. Substitute for the mechanical/electrical contact, the judgment is carried out by calculating the measurement data obtained. This provides high reliability with no deterioration of the contact point and volume adjustment. The signal can be output to an external device like a sequencer through the NPN open-collector. The GO/NG judgment result is also indicated by the green/red LED and the "" signs on LCD. Employing the ABSOLUTE linear encoder, the Signal ID-C always displays the spindle "Absolute Position" from the origin at power-on. The Signal ID-C achieves the IP54 protection level to resist dust and contaminants for safe operation in harsh machine shop environments.
