Allen Bradley 1388B-AV40

The Allen-Bradley 1388B-AV40 is a Servo Controller module from the Bulleting 1388B. It is specifically a DC servo controller that is compatible for use with Allen-Bradley’s 1388 Anti-Backlash system. This device is a Series B controller with an open frame and provided with an internal heatsink. The nominal output voltage under a load of this controller is 150VDC, continuous current rating of 40 Amperes, a peak output current of 100 Amperes, and rated output power of 3.0 kW with minimum load inductance of 0.4 milliHenry. the 1388-AV40 operates when connected to a 120 VAC, 3-Phase supply voltage with a frequency of 50/60 Hz along with an input current of 20 Amperes. It has a VCT of 35.5 VAC, 1-phase and frequency of 50/60 Hz, and a current of 1.6 Amperes. This controller has a maximum short circuit current of 1600 Amperes(rms). When connecting power wires to terminals 1-6 of this servo controller, use 8-18 AWG copper wires with 75 Degree Celsius insulation rating. Apply 32 lb-in tightening Torque to the terminals to secure connection. Similarly, power wiring connections for terminals 7-12 require the use of 10-20 coppers wires with the same insulation rating however, the appropriate tightening Torque is 18 lb-in. For control wiring, use terminals TB1 and TB2 mounted on the control Printed Circuit Board (PCB) of the controller. Apply tightening torque amounting to 5 lb-in using a control wire size of 12-22 AWG with 75 Degree Celsius insulation rating. This servo controller is provided with LED status indicators mounted on the module’s front panel. These LED indicators include Motor overload, undervoltage, overvoltage, current foldback, overtemperature, transistor overcurrent, and module enabled.

The servo controller with product code 1388B-AV40 is Series B servo controller and it is manufactured by Allen-Bradley/Rockwell Automation. The 1388B-AV40 controller features intuitive operation and it allows simple on-site adjustments and simple setup of the functional parameters. The integration of this servo controller will enhance the operation of the servo motor and it provides protective features such as a speed-dependent current limit, electronic motor thermal overload detection (MODR), power amplifier inverse time overload detection, power bus over/under voltage detection, and logic supply under voltage detection. The 1388B-AV40 servo motor has 150 Volts DC nominal output voltage and it provides a continuous current of 40 Amps with a peak current of 100 Amps. The controller includes an internal dynamic braking resistor with an electric resistance of 1 Ohm. The power rating of the featured braking resistor is 100 Watts.

The 1388B-AV40 controller also has a continuous power output of 3 kilowatts along with a peak power output of 15 kilowatts. The power capacity of 6 Ohms internal shunt regulator is 51 Watts. In addition to that, the interrupt rating of the circuit breaker is 5000 Amps. In regard to other specifications of the controller, it includes a form factor of 1.03 or less, a peak current limit adjustment of 10 to 250% of the rated current, and of 85% drive efficiency. The input voltage of the 1388B-AV40 controller is 120 Volts AC (3-phase) for power and 35.5 Volts AC C.T. (single-phase) for control. The weight of the unit is 10.4 kilograms (23 pounds). All the Series B 1388 controllers are built for industrial operating conditions which include an ambient temperature range of 0 to 60 degrees Celsius, 5 to 95% relative humidity, and 1000 meters of maximum operating altitude.
