The MD500 supports both PT100 and PT1000. Make sure to set the sensor type correctly. You can view the motor temperature in
U0-34.
7.6.6 Power Dip Ride-through
The power dip ride-through function ensures the system to run continuously at occurrence of momentary power down.
When an instantaneous power loss or a sudden power dip occurs, the AC drive compensates the DC bus voltage reduction with
the real-time energy feedback by reducing the output frequency, preventing the AC drive from stopping due to undervoltage.
