The TMCM-171 is a controller / driver module for high performance servo drives based on brushless DC motors. It combines the high resolution of a stepper motor coupled with the high dynamic, high velocity and high reliability of a BLDC drive. The motor and switches can be connected easily with pluggable screw terminals. A build-in ramp generator allows parameterized smooth positioning. The TMCM-171 supports BLDC motors with nearly any number of poles and incremental encoders with nearly any resolution.The TMCM-171 integrates a velocity regulator, a position regulator and a ramp generator. The module can be controlled remotely via CAN or RS-485 interface. Additionally, the TMCM-171 is equipped with a step direction interface. Stand alone operation (either via TMCL program or via analog control) is also possible. Applications * Replacement of servo drive by high reliability / low cost BLDC drive * Fast and precise positioning * Smooth very low to very high constant / variable velocity drives * Very high velocity stability drives * Sine (or block) commutated BLDC motors with encoder and with / without additional hall sensors * Hall sensor based motors can be operated without encoder * Motor power from a few watts to 800W * Motor velocity up to 100,000 RPM (electrical field) * Incremental encoder (2 channel with option for N-channel) with resolution from 256 to 30000 / motor rotation (opt. per electrical field rotation) * 12V to 48V nominal motor voltage * RMS motor current up to 20A (sine commutation)
