• The frequency converter is protected against short-circuiting on motor terminals U, V, W.
• The frequency converter is protected against earth fault on motor terminals U, V, W.
• Monitoring of the intermediate circuit voltage ensures that the frequency converter cuts out if the intermediate circuit voltage becomes
too high or too low.
• If a motor phase is missing, the frequency converter cuts out, see parameter 234 Motor phase monitor.
• If there is a mains fault, the frequency converter is able to carry out a controlled decelleration.
