20DD125A3EYNACNNN

The 20DD125A3EYNACNNN is an adjustable frequency AC drive manufactured by Allen-Bradley under the PowerFlex 700S series. The module operates with a voltage of 480 Volts AC. the 20DD125A3EYNACNNN is a 3-phase drive featuring the IGBT braking system. It is also an adjustable bus undervoltage trip drive with a full numeric LCD human-machine interface. The LCD feature is important for ensuring that the machine performs as expected. The human-machine interface is used for entering the controls and the configurations to the module. The human-machine interface can be unplugged or plugged to the drive while the drive is functioning.

The 20DD125A3EYNACNNN features an IP20 NEMA Type 1 enclosure and it comes with 0.25 seconds drive of Logic control ride thru time when it is not running. The 20DD125A3EYNACNNN has a power ride thru capacity of 15 milliseconds at a full load. PowerFlex 700S drives come with a permanent magnet control used with a permanent magnet motor. The permanent magnet motor control will require either the Hi-Resolution Stegmann encoder or the compatible resolver feedback on the motor. For the PowerFlex 700S module to function well, it is required that the motor data and an Autotune feature be used. These will ensure that there is correct operation in the given machine mode. The 20DD125A3EYNACNNN and other PowerFlex 700S modules will use the Volts/Hertz control in fan, pump, or the multiple motor applications. The Volts or Hertz control causes or creates a fixed relationship between the output voltage and the output frequency. The Volts/Hertz control will also allow for a wide variety of patterns using the linear segments.
