Mains failure

What does 36 mean?

The frequency converter has detected a loss of incoming supply voltage, and the 'Mains Failure' parameter (14-10) is configured to generate an alarm. This indicates a power supply interruption to the drive, which will cause the motor to stop. Until mains power is restored, the drive cannot operate.
