Analog servo controller TRA for 2 axes
The devices in the TRA series consist of two independently operating analog servo controllers for permanently excited DC motors, which are operated on the same DC link.
Both controllers, the shared power supply, and a switching power supply for the electronics of both axes are mounted on a double Eurocard. This allows for highly economical solutions in terms of cost, space, and energy consumption. These controllers are especially suited for applications requiring two or more axes, such as X-Y drives or winding machines.
The device can be supplied as a pure current controller, or—by adding a plug-in module—as a speed controller with tachometer feedback or back-EMF / IxR regulation. The use of SMD technology and power MOSFETs ensures high efficiency and a compact design. The installation height is only 8 HP (height units).
The devices are short-circuit and ground-fault resistant and include all common control, protection, and monitoring functions. Nominal voltages of 60 V and 120 V, and nominal currents of 6 A and 12 A, are supported. For acceleration and braking, a 2.5x peak current is available for approx. 3 seconds.
