High duty-cycle acceleration\/deceleration steps can lead to a regenerative overvoltage fault (AL.30 or AL.50). Ensure that if an external regenerative resistor is installed, the short-circuit bar across P and Cr is fully removed, and the alternative parameter group is updated to prevent severe damage to the internal power transistors.\u003c\/p\u003e\n\n\u003ch3\u003eCommissioning \u0026amp; Wiring Tips\u003c\/h3\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003eAlways route the high-voltage motor output lines (U, V, W) in a separate run from the CN2 encoder feed and control signaling lines.
