The 1336VT-B025-EOP-FA2-L3 is a microprocessor-based, adjustable frequency drive with high-performance features and exceptional control capabilities. This 1336VT series was designed by Allen-Bradley to control 3-phase induction motors on precarious industrial applications. This part produces an adjustable, 3-phase frequency output in order to supply an adaptable motor speed. This drive’s output voltage is typically a function of the output frequency and can be modified to match specific motor parameters to achieve optimum performance. As a digitally programmable product, the 1336VT-B025-EOP-FA2-L3 control panel offers precise and constantly accurate control; it can be programmed through the serial communication port or from a local/remote Control Panel. Depending on the configuration, numerous status and fault settings are reported through the Programming & Display Panel or via the Serial Communications Port. Whenever the drive is powered, all fault diagnostics begin with both load and drive self-check diagnostics. Whilst running, the 1336VT-B025-EOP-FA2-L3 continues to monitor probable fault conditions. To permit real-time preventive maintenance, power specs such as control conditions and drive output current can continuously be monitored even when the device is running. In the event that a fault occurs, detailed diagnostic codes separate the problem to detect the condition, permitting quick, corrective measures to be undertaken in order to restore normal process control.

The 1336VT-B025-EOP-FA2-L3, an adaptable AC frequency drive, is designed for use with standard, 3-phase induction motors and provides an outstanding output voltage as well as a current waveform. The drive’s standard control has a constant torque and variable speed control featuring 115% overload capability. In addition, this product is customizable through programming to support an extensive range of applications. However, special considerations must be taken when fitting an inverter on an existing motor. Adjusting the frequency of the power applied to the motor varies the motor speed. That’s why the 1336VT-B025-EOP-FA2-L3 is intended for use with adjustable torque, cubed law loads, and square law. With cubed law loads (fans & blowers and some centrifugal pumps), the horsepower changes as the cubic speed changes while torque changes as the square of speed vary. With square law loads (extruders & mixers, and some positive displacements), the torque varies directly with speed changes while horsepower changes with the change in the square of speed.

The size of the 1336VT-B025-EOP-FA2-L3 should be determined by the required motor load current at maximum operative speed. When operated for lengthy periods of time at the rated torque and below 50% base speed, induction motors may overheat due to the reduced airflow of fans. Motors might also require special balancing if they are operated at or above 125% of the base speed. The 1336VT-B025-EOP-FA2-L3 is generally suitable for direct connection to a 3-phase AC power system; however, there are certain power line situations that might cause drive input component malfunction. To avoid such conditions, an isolation or line reactor type transformer might be required. The 1336VT-B025-EOP-FA2-L3 provides a 3-phase motor with an adjustable frequency voltage, using Pulse Width Modulated (PWM) technology. It uses ninety programmable parameters to select & control drive operation; if a 2-wire control is installed, also install options L1, L2, 0r L3.
