6 / 157 page TMC4671 Datasheet • IC Version V1.00 | Document Revision V1.04 • 2018-Dec-11 6 / 157 2 Functional Summary • Servo Controller with Field Oriented Control (FOC) – Torque (and ux) control mode – Velocity control mode – Position control mode – update rate of current controller and PWM at maximum frequency of 100 kHz (speed and position controller update rate is con gurable by setting a divider of current controller update rate) • Control Functions/PI Controllers – Programmable clipping of inputs and outputs of interim results – Integrator windup protection for all controllers – Programmable eld oriented voltage circular ( U 2 D + U 2 Q ) limiter – Feed-forward offsets for target values and feed-forward friction compensation – Advanced feed-forward control structure for optimal trajectory tracking performance – Extended IRQ event masking options and limiter status register – Advanced encoder initialization algorithms with Hall sensor or/and with minimal movement • Supported Motor Types – FOC3 : 3-phase permanent magnet synchronous motors (PMSM) – FOC2 : 2-phase stepper motors – DC1 : brushed DC motors, or linear voice coil motors • ADC Engine with Offset Correction and Scaling – Integrated ∆Σ ADCs for current sense voltage, motor supply voltage, analog encoder, two AGPIs – Integrated ∆Σ-Interface for external ∆Σ-Modulators • Position Feedback Evaluation – Open loop position generator (programmable [rpm], [rpm/s]) for initial setup – Digital incremental encoder (ABN resp. ABZ, up to 5 MHz) – Secondary digital incremental encoder – Digital Hall sensor interface (H1, H2, H3 resp. HU , HV , HW ) with interpolation of interim positions – Analog encoder/analog Hall sensor interface (SinCos (0°, 90°) or 0°, 120°, 240°) – multi-turn position counter (32-bit) – Position target, velocity and target torque lters (Biquad) • PWM Engine Including SVPWM – Programmable PWM frequency within the range of 20 kHz . . . 100 kHz – Programmable Brake-Before-Make (BBM) times (high side, low side) 0 ns . . . 2.5 µs in 10 ns steps and gate driver input signals – PWM auto scaling for transparent change of PWM frequency during motion • SPI Communication Interface – 40-bit datagram length (1 ReadWrite bit + 7 address bits + 32 data bits) ©2018 TRINAMIC Motion Control GmbH & Co.
