| Very low electrical noise 25W continuous/50W peak 5Khz bandwidth Integral forced-air cooling Digital on-the-fly gain control (DTS) Over temperature protection Selectable current limit Applications voice coil motors x-y micro stages metrology tools small DC motors A robust linear amplifier, built to provide quiet and smooth power to brush motors. The TA105 is a linear servo motor amplifier, designed to drive a brush motor with up to 50W of power. The TA105 is an excellent solution for voice-coil type motors, high-precision positioning applications, and systems requiring ultra-quiet driving power, when low-noise operation is essential. Trust Automation's Dynamic Transconductance Selection (DTS) feature allows changing the amplifier's torque gain on-the-fly thus permitting high-resolution control, without sacrificing power capability. DTS is included on all of Trust Automation's amplifiers. The TA105 can be operated in voltage (velocity) mode or current (torque) mode; selected via a user-accessible DIP switch. Fault logic is also selectable via a DIP switch. Trust Automation is committed to products that are easy to install and use. Amplifier connections are made via pluggable-terminal connectors. Therefore, all connections are easily installed and removed, which reduces hardware cost, and assembly time. 205 Suburban Road x San Luis Obispo, CA 93401 Phone: (805) 544-0761 x Fax: (805) 544-4621 www.TrustAutomation.com Connector Pinouts Connector - J1 Wago P/N 733-110 Connector - J2 Wago P/N 734-105 Pin 1 2 3 4 5 6 7 8 9 10 Description Pin Description 1 Motor + Command Signal Input A+ 2 Motor Command Signal Input A3 GND Aux Gnd 4 GND Aux Gnd 5 VSUPPLY (15-48VDC) Dynamic Transconductance Select Bit D0 Dynamic Transconductance Select Bit D1 /ENABLE* *Referenced to Aux Gnd FAULT* **User-supplied/connected for optical isolation (optional) Aux Gnd ***Referenced to GND VAUX (user-supplied +5V)** Switch Settings S1 - System Configuration SW# DOWN 1 2 3 4 5 6 TA105-supplied +5V (20mA max) Aux Gnd tied to GND /FAULT Current mode DTS bit 0 DTS bit 1 UP User-supplied +5V (for optical isolation) Aux Gnd isolated from GND FAULT Voltage mode (Av=20) Gain - Transconductance & DTS Setting S1-5 S1-6 10V 10V 10V 10V in in in in = = = = 0.5A 1.0A 1.5A 2.0A out out out out Down Up Down Up (0) (1) (0) (1) Down Down Up Up (0) (0) (1) (1) NOTE: S1-5, S1-6 are shown UP.
