The 1336S-BRF75-AA-EN3-L6 drive is an operator interface equipped AC drive. The drive has been manufactured by Allen-Bradley. The drive supports an intermittent overload capacity with both constant and variable torque. With constant torque, the drive can support 150% of the rated output for 1 minute and with variable torque, the drive can support 115% of the rated output for a time period of 1 minute. The 1336S-BRF75-AA-EN3-L6 drive is also equipped with a current limit capability with a proactive current limit that is programmable from 20 to 160% of the rated output current. It supports both independently programmable proportional and integral gains. The line loss restart is a standard feature in this drive. It provides a variety of programmable selections to control the timing and method of reconnecting the motor after the power returns in a line loss condition. It can also be used with the flying start feature to determine the motor speed of the drive. It can also check for the terminal voltage for determining the motor speed.

The 1336S-BRF75-AA-EN3-L6 drive runs with an input AC voltage range from 380 to 480 Volts AC or 513 to 620 Volts DC. The drive features an improved Class 10 level of protection to save the drive from motor overloading. Operation at the full load current will increase the overload from its trip level. The frequency accuracy of the drive supports both digital and analog input. With digital input, the output frequency of the drive is within a +/- 0.01% range, and with analog input, the output frequency is within a +/- 0.4% range. One very common use for this drive in industrial applications is to control the speed of a water pump in a water treatment facility. This is achieved by using the 1336S-BRF75-AA-EN3-L6 drive on the AC motor that powers the pump.
