can be pre-configured via the interface. stealthChop2 allows high motor dynamics, by reacting at once

to a change of motor velocity.

For highest dynamic applications, spreadCycle is an option to stealthChop2. It can be enabled via

input pin (standalone mode) or via SPI or UART interface. stealthChop2 and spreadCycle may even be

used in a combined configuration for the best of both worlds: stealthChop2 for no-noise stand still,

silent and smooth performance, spreadCycle at higher velocity for high dynamics and highest peak

velocity at low vibration.

spreadCycle is an advanced cycle-by-cycle chopper mode. It offers smooth operation and good

resonance dampening over a wide range of speed and load. The spreadCycle chopper scheme

automatically integrates and tunes fast decay cycles to guarantee smooth zero crossing performance.

Benefits of using stealthChop2:

Significantly improved microstepping with low cost motors

Motor runs smooth and quiet

Absolutely no standby noise

Reduced mechanical resonance yields improved torque

1.7 stallGuard2 – Mechanical Load Sensing

stallGuard2 provides an accurate measurement of the load on the motor. It can be used for stall

detection as well as other uses at loads below those which stall the motor, such as coolStep load-

adaptive current reduction. This gives more information on the drive allowing functions like

sensorless homing and diagnostics of the drive mechanics.

1.8 coolStep – Load Adaptive Current Control

coolStep drives the motor at the optimum current. It uses the stallGuard2 load measurement

information to adjust the motor current to the minimum amount required in the actual load situation.

This saves energy and keeps the components cool.

Benefits are:

Energy efficiency

power consumption decreased up to 75%

Motor generates less heat

improved mechanical precision

Less or no cooling

improved reliability

Use of smaller motor

less torque reserve required → cheaper motor does the job

Figure 1.5 shows the efficiency gain of a 42mm stepper motor when using coolStep compared to

standard operation with 50% of torque reserve. coolStep is enabled above 60RPM in the example.
