Compact 4-quadrant positioning motion controllers

26 September 2015

Pittman Motors' new BGE Series of servomotor controllers is a family of compact 4-quadrant positioning motion controllers with integral output stage to control Pittman brushless and brushed dc motors.

The motion controllers can be operated in stand-alone operation with digital or analogue I/O or as a slave in a CANopen network with device profile DSP 402, protocol DS 301. The family of motion controllers is rated from 12Vdc to 60Vdc input voltage and 4-20A continuous output current. 

Information about the motor’s rotor position can be supplied to the positioning controller by an encoder or integrated Hall sensors contained within a brushless motor. The controls incorporate protection against over-voltage, low voltage and excessive temperature.

If 4-quadrant digital speed control is desired, the control can be commanded to run in either direction, stop and hold with torque, and stop without torque (coast) through digital inputs. Other inputs can switch between programmed speeds or allow for a variable analogue speed reference. 

Acceleration/deceleration ramps for the motor also can be programmed. The control offers the capability for a motor to function as a stand-alone or programmed servo, which interfaces to the rest of the machine via digital and analogue I/O.

If only speed control is required for an application, the BGE 3004A, a cost-optimised 1-quadrant controller, is available.  BGE controllers are available from stock at the Pittman Express E-Commerce store.
