Cause: Short circuit comes when there is short circuit between motor or motor cable. This fault also comes when there ia an hardware issue in drive.

alarm 16 danfoss indicates short circuit. This means the drive detected a short-circuit (phase-to-phase or phase-to-ground) at the motor connection terminals.

Troubleshooting Steps:

Follow these steps to correct alarm 16 danfoss:

• Check the motor cable for any signs of damage, cuts, or abrasions.
• Check the connections at the drive's output terminals (U, V, W) for any loose or incorrect wiring.
• Use a multimeter to check the resistance between all three motor phases (U-V, U-W, V-W).
