Gate drive voltage low

What does ALARM 46 mean?

The supply voltage on the power card, which generates 24 V, 5 V, and ±18 V, is out of range. This indicates a problem with the switch mode power supply (SMPS) on the power card, affecting the drive's ability to control the motor's power transistors.
