1–4 Overview of the Incremental Encoder Module How the incremental encoder Operates The counter module handles up/down counting and detection of selectable number of edges (X1, X2, X4) for incremental encoders with 2 pulse trains, nominal 90o out of phase. The minimum stable input condition is 2µs.The following paragraphs detail operation of the incremental encoder module. Each of the 2 counters has a 16–bit counter register, a preset register and a latch register.

Calibrating Your Incremental Encoder Module Chapter Objective Calibrating Your Module In this chapter, we tell you how to set up your system to calibrate the incremental encoder. The incremental encoder module does not require calibration. However, you must synchronize the module with the process you are monitoring. You must have your incremental encoder module installed in an operating FLEX I/O system in order to complete synchronization.
7–2 Calibrating Your Incremental Encoder Module Calibration Method 1 Calibration is enabled by the flag CalEnable, which is enabled by the control system. The preset value is copied to the counter register at a positive edge on input Z. The old counter register value is saved in the store register for evalution. Calibration direction is determined by CalDirection (0 = positive direction, 1 = negative direction).
Calibrating Your Incremental Encoder Module 7–3 Calibration Method 2 Calibration is enabled by input G if GateControl = 3 and Calibrated = 0. The preset value is copied to the counter register at a positive edge on input signal Z. The old counter register value is saved in the store register for evalution. Calibration direction is determined by CalDirection (0 = positive direction, 1 = negative direction).

Troubleshoot the Incremental Encoder Module What This Chapter Contains Use this chapter to troubleshoot the incremental encoder module by interpreting the indicators. Status Indicators The module contains indicators for each of the following: 1794-ID2 2 CH INCREMENTAL ENCODER MODULE A B Z G + - C A B B Z 1 G + - A A = Power/status indicator – indicates power applied to module and status of module. B = Insertable label for writing individual I/O assignments.
8–2 Troubleshoot the Incremental Encoder Module Indicator Indication Explanation A Yellow Input A active Off Input A not active Yellow Input B active Off Input B not active Yellow Input Z active Off Input Z not active Yellow Input G active Off Input G not active + Yellow On when a positive pulse is detected; turns off on negative pulse. - Yellow On when a negative pulse is detected; turns off on positive pulse.
