Description

Bantam is a compact, DC-powered analog current amplifier for torque control of DC brush or brushless motors. It operates as a stand-alone driver taking a ±10V input from an external controller. Mounting to a PC board with solderless connectors facilitates low-cost, multi-axis designs. Specifications CONTINUOUS CURRENT 10A PEAK CURRENT 20A SUPPLY VOLTAGE 12-55 VDC DIMENSIONS 53.3 x 45.7 x 15.2 mm DIGITAL INPUTS 4 DIGITAL OUTPUTS 3 FEEDBACK Digital Halls COMMAND INTERFACE Analog ENVIRONMENT Commercial Analog Inputs • ±10 Vdc current reference • Peak, continuous current & peak-time set Analog Outputs • Current monitor • Current reference Digital Inputs • Amp Enable • Fwd/Rev Enable (limit switches) • Hi/Lo load inductance Digital Outputs • Amp OK • Regen control • Brake control Feedback • Digital Halls from brushless motors Dimensions • 53.3 x 45.7 x 15.2 mm • 2.1 x 1.8 x 0.6 in Description The Amp Enable input interfaces to active LO signals up to 24 Vdc. Another digital input switches the current-loop gain from a high to low for load inductance compensation. Forward and Reverse Enable inputs are provided for limit switches. A digital output for Amp-OK indicates the amplifier’s status. There are two other digital outputs one of which can activate an external regenerative energy dissipator circuit and another for motor brake control. Digital Hall feedback enables trapezoidal drive of DC brushless motors. For driving DC brush motors, these inputs are left unconnected and the motor connected between the U & V outputs. Protections include I2T current limiting for peak and continuous current as well as peak time. Short circuits between outputs or to
