Data record instr.phase-sequence-indicator.motor-rotation-direction

Verified 2026-10-27 Confidence: High

Some indicators also determine the direction of rotation of a three-phase motor: on a running motor without test leads, by sensing the motor from outside, and on a disconnected motor when the shaft is turned by hand; this serves motors whose shaft cannot be seen.
