The TI-5000EX accepts encoders with single ended or differential output lines, with or without an index pulse (although some tests require an index pulse). If the encoder includes U, V, and W true and complement commutation lines, those lines can be checked as well. In Data Display the count, count rate, and line states (including commutation lines) are displayed. Testing of the encoder outputs includes measuring counts between index pulses, measuring A, B and Z channel line levels, and measuring three different pulse phase angles.

To aid in checking and setting commutation alignment, the encoder counts are also used to calculate and display mechanical and electrical angles. Correct electrical angle calculation requires the operator to enter the number of motor poles.

TESTING

COUNT TEST - Turn by hand and compare measured counts per rotation with target number.

CONTINUOUS COUNT TEST - Count test while turning continuously with a motor.

PHASE TEST - Measure A and B channel phase angles while turning by hand or by motor.
