The LGD series of motor drives is a versatile and compact SCR drive designed for any 1Q application where a field output is not required. With most of the features offered by the LGC family of drives, the LGD series offers even more flexibility. Unlike the LGC series where it’s inhibit function is actuated by the closing of the inhibit terminals, the LGD series allows you to choose either to open or close to inhibit. Other user selectable features include inhibiting to zero or to minimum speed, and torque mode or speed mode operation. With the unit set up to run in torque mode, you can easily control the amount of current that is supplied to your motor via an external potentiometer, perfect for tensioning applications. This feature rich series is easily adapted to meet almost any application need.
