The 74101-169-57 unit is an Allen-Bradley PCB Gate Drive Board; this module has an alternative part number of 1336-BDB-SP38D. The 74101-169-57 a has 460 Volt AC voltage and its horsepower is around 200 Hp. The unit fits perfectly with same frame sizes of A, B, C, D and E, and features space-saving packaging and a Human Module Interface (HMI) that is surprisingly fast to program and easy to read and understand. This module also has features such as motor speed regulation and communication capabilities. The 74101-169-57 unit provides high-performance control of an AC motor and is ideal for control applications, as it features accurate speed and torque control. It has good control of torque at all speeds and easy to use parameters that are arranged in groups in order to offer prompt access to related functions. The 74101-169-57 unit features a field oriented control, which gives the precise speed and torque control of an AC motor. Auto-tuning speed and torque loop, dynamic braking values, two jog speeds, selectable speed/torque modes, programmable velocity loop, electronic motor overload, programmable setpoints, separately adjustable deceleration/acceleration times are some of the programmable features of this 74101-169-57 unit.

The small size of this module saves panel space and the laminar bus design decreases its internal inductance, which assists in improving the performance of Insulated Gate Bipolar Transistors (IGBT). additionally, the IGBT structure technology offers consistent current output to the motor, which in turn reduces the motor heating. The 74101-169-57 unit offers flexibility, as its parameter linking feature provides control over how information is used. When it comes to the motor’s temperature, this module can compensation without a motor sensor.
