1.1 Key Concepts
The TMC2160 implements advanced features which are exclusive to TRINAMIC products. These features
contribute toward greater precision, greater energy efficiency, higher reliability, smoother motion, and
cooler operation in many stepper motor applications.
stealthChop2™ No-noise, high-precision chopper algorithm for inaudible motion and inaudible
standstill of the motor. Allows faster motor acceleration and deceleration than
stealthChop™ and extends stealthChop to low stand still motor currents.
spreadCycle™ High-precision chopper algorithm for highly dynamic motion and absolutely clean
current wave. Low noise, low resonance and low vibration chopper.
dcStep™
Load dependent speed control. The motor moves as fast as possible and never loses
a step.
stallGuard2™
coolStep™
Sensorless stall detection and mechanical load measurement.
Load-adaptive current control reducing energy consumption by as much as 75%.
microPlyer™
Microstep interpolator for obtaining full 256 microstep smoothness with lower
resolution step inputs starting from fullstep
In addition to these performance enhancements, TRINAMIC motor drivers offer safeguards to detect
and protect against shorted outputs, output open-circuit, overtemperature, and undervoltage
conditions for enhancing safety and recovery from equipment malfunctions.
1.2 Control Interfaces
The TMC2160 supports an SPI interface for parameter setting and diagnostics. Additionally, a
standalone mode is provided for pure STEP/DIR operation without use of the serial interface. Selection
of the actual interface is done via the configuration pin SPI_MODE, which can be hardwired to GND or
VCC_IO depending on the desired interface.
