The 1336F-B020-AA-EN-GMS1-LA4-L6 drive is an Allen-Bradley 1336 PLUS II series adjustable frequency drive. An adjustable frequency drive is an industrial drive used for the control of motor speed and torque. The drive does this by varying the input frequency that it applies to the connected motor. The range of output frequencies supported by the 1336F-B020-AA-EN-GMS1-LA4-L6 drive is from 0 to 400 Hertz. Its input voltage rating is 280 to 480 Volts AC with 50 to 60 Hertz of operating frequency and 47 to 63 Hertz of tolerable frequency. The voltage at the drive output varies with the input and it ranges from 0 to the rated voltage. A motor circuit protector can be used at the drive output to protect the motor from overcurrent. The maximum current rating of the 1336F-B020-AA-EN-GMS1-LA4-L6 adjustable frequency drive’s motor protector as specified in the product manual is 50 Amps.
The Allen-Bradley 1336F-B020-AA-EN-GMS1-LA4-L6 1336 PLUS II series drive does not support integrated input overcurrent protection. However, Allen-Bradley has specified the current ratings for the optional fuses and circuit breakers that can be used for drive input protection if required. Two types of fuses can be used: dual-element time delay fuses and non-time delay fuses. The minimum and maximum recommended ratings for dual element time delay fuses are 45 Amps and 70 Amps, respectively. The minimum and maximum recommended ratings for non-time delay fuses are 45 Amps and 125 Amps, respectively. Circuit breakers can also be used for drive input protection, and the maximum recommended ratings for these circuit breakers is 125 Amps. The rated output power of the 1336F-B020-AA-EN-GMS1-LA4-L6 drive is 20 Horsepower. The drive enclosure is IP 20 rated. The control interface on the drive operates at 115 Volts AC. An optional analog interface module installed on the 1336F-B020-AA-EN-GMS1-LA4-L6 drive supports one isolated and configurable input and output.
