Figure 1.1 Basic application and block diagram

The TMC5062 motion controller and driver chip is an intelligent power component interfacing between

the CPU and up to two stepper motors. All stepper motor logic is completely within the TMC5062. No

software is required to control the motor – just provide target positions. The TMC5062 offers a

number of unique enhancements which are enabled by the system-on-chip integration of driver and

controller. The sixPoint ramp generator of the TMC5062 uses dcStep, coolStep, and stallGuard2

automatically to optimize every motor movement: TRINAMICs special features contribute toward lower

system cost, greater precision, greater energy efficiency, smoother motion, and cooler operation in

stepper motor applications. The clear concept and the comprehensive solution save design-in time.

1.1 Key Concepts

The TMC5062 implements several 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.

dcStep™

stallGuard2™

coolStep™

spreadCycle™

sixPoint™

Load dependent speed control. The motor moves as fast as possible and never loses

a step.

High-precision load measurement using the back EMF on the motor coils.

Load-adaptive current control which reduces energy consumption by as much as

75%.

High-precision chopper algorithm available as an alternative to the traditional

constant off-time algorithm.

Fast and precise positioning using a hardware ramp generator with a set of four

acceleration / deceleration settings. Quickest response due to dedicated hardware.
